Temperature Sensor : Types, Applications, Working Principle and Much More

　　A temperature sensor is a vital component in many systems where monitoring or controlling of temperature is required.　　It allows one to measure the temperature of an object or environment and provide thermal data which is further used by various devices and applications.　　Temperature sensors play an important role across many industries from automotive and medical to consumer appliances.　　What is a temperature sensor?A temperature sensor is a device that helps in measuring the temperature of its environment, object or substance and converts the measurement into an electronic signal.　　This electronic signal is further processed by auxiliary instrumentation such as temperature indicators, temperature controllers and temperature recorders to display or use the temperature data.　　There are various types of temperature sensors available based on different sensing technologies like thermistor, thermocouple, Resistance Temperature Detector (RTD) etc.　　What are different types of temperature sensors?Some of the common types of temperature sensors are:　　Thermocouple　　A thermocouple is a temperature sensor made by joining two different conductors at their ends to form a thermocouple junction. The voltage produced is dependent on the temperature difference between the thermocouple junction and a reference junction. Thermocouples are inexpensive, rugged and can measure a wide range of temperatures.　　Resistance Temperature Detector (RTD)　　An RTD is made up of a pure metal like platinum, copper or nickel which exhibits change in electrical resistance when exposed to change in temperature. The resistance increases linearly as temperature rises which makes it easy to convert to temperature using a simple formula. RTDs provide good accuracy over a wide temperature range.　　Thermistor　　A thermistor is a type of resistor whose resistance varies significantly with temperature changes. It exhibits a non-linear but known resistance-to-temperature relationship. Negative temperature coefficient (NTC) thermistors decrease in resistance with rising temperature while positive temperature coefficient (PTC) thermistors increase in resistance. They provide high accuracy and fast response time.　　Integrated Circuit Sensor　　An integrated circuit temperature sensor consists of a temperature sensitive circuit integrated onto a silicon chip that outputs voltage proportional to sensed temperature. They are small in size, inexpensive and mass producible. But accuracy is less as compared to other sensor types.　　Infrared Sensor　　Infrared sensors detect infrared energy radiated from an object or surface and produce an electronic signal proportional to the temperature. They are contactless and suitable to measure temperature without disturbing the environment but have less accuracy.　　What are the advantages and disadvantages of temperature sensors?Advantages　　• Provide accurate and repeatable temperature measurements.　　• Respond quickly to temperature variations.　　• Can measure a wide range of temperatures from below zero to thousands of degrees Celsius depending on type.　　• Rugged, withstand vibrations and withstand hostile environmental conditions like humidity and pressure.　　• Low cost options available for general purpose temperature measurements.　　• Integrated circuit temperature sensors are small, mass producible and inexpensive.　　Disadvantages　　• Contact sensors disturb the medium whose temperature is being measured.　　• Thermocouples produce small voltage signals requiring amplification.　　• Response time of temperature sensors depends on thermal mass and insulation which limits fast temperature tracking.　　• Temperature sensors have limited lifespan and require calibration over time.　　• Special sensors are needed for measuring ultra-low or ultra-high temperatures.　　How important is a temperature sensor?　　A temperature sensor plays a vital role in maintaining quality and safety standards across many industries.　　Some key applications where temperature sensors are mission critical include:　　• Medical equipment and patient monitoring – Ensures safe temperatures for drug infusion, surgical/therapy devices, incubators etc.　　• Automotive – Monitors engine temperature, fuel systems, brake fluid, transmission oil, exhaust gas recirculation.　　• Industrial manufacturing – Controls processes in plastics molding, food processing, chemical reactions requiring specific temperatures.　　• HVAC equipment – Essential component in thermostats, air conditioners, refrigerators to regulate temperatures.　　• Fire/overheat detection – Prevents accidents by triggering alarms when abnormal high temperatures detected.　　• Consumer appliances – Maintains safe cooking temperatures in ovens/stoves, cool temperatures in refrigerators.　　Where are temperature sensors used?Industrial applications　　Oil and gas plants to monitor pipeline temperatures, boiler temperatures.　　Pulp and paper industry for dryer skin temperatures, consistency measurements.　　Power plants to monitor transformer temperatures, boiler steam temperatures.　　Iron and steel industry for molten metal temperatures, annealing furnace controls.　　Automotive　　Engine coolant temperature sensor in radiator.　　Intake air temperature sensor.　　Exhaust gas temperature sensor before catalytic converter.　　Transmission fluid temperature sensor.　　Rear differential and transfer case temperature sensors.　　Medical　　Patient thermoregulation- temperature probes in incubators, warming blankets.　　Medical sterilizers- monitors autoclave temperatures.　　Hyperthermia therapy- controls localized temperature increases.　　HVAC　　Thermostat temperature sensor　　Duct-mounted temperature sensors　　Outdoor temperature sensors　　Household appliances　　Refrigerator/freezer temperature sensors　　Oven temperature sensors　　Water heater thermostats　　What is the difference between thermal sensor and temperature sensor?The main difference between a thermal sensor and a temperature sensor are:　　Thermal sensors detect heat without direct contact while temperature sensors measure temperature through properties like resistance that change with temperature.　　Thermal sensors provide relative heat indication without units while temperature sensors provide measured temperature output in units like Celsius or Fahrenheit.　　How do temperature sensors work?Temperature sensors function based on different working principles depending on the sensing technology used:　　Thermistors　　Thermistors are made from semiconductor materials that change resistance predictably with temperature changes. As temperature rises, the mobility of charge carriers in the semiconductor increases resulting in lower electrical resistance that can be measured.　　Thermocouples　　When two different conductors are joined together, a voltage is produced dependent on their Seebeck coefficient and the temperature difference between the junction and reference junction. The output voltage is linearly proportional to temperature and is measured.　　RTDs　　Resistance Temperature Detectors use metals like platinum that change resistance reliably with temperature. Resistance increases linearly as temperature rises following PRT (Platinum Resistance Thermometers) or ITS-90 standard curves.　　Integrated circuits　　Complementary metal–oxide–semiconductors (CMOS) and bipolar transistors on an IC change current or voltage levels proportionally to temperature which is output analog or digital signals.　　Infrared sensors　　Infrared sensors contain a detector which absorbs infrared radiation from the target. The absorbed IR energy causes the detector temperature to rise above ambient. This temperature change alters the electrical properties to provide an output signal related to target temperature.　　How to design a temperature sensor?　　The steps involved in designing a temperature sensor are:　　1. Select sensing element material based on required temperature range, accuracy, response time etc. like RTD, thermistor etc.　　2. Design sensor probe matching application requirements like immersion, surface, air temperature sensing.　　3. Choose appropriate housing material that withstands application environment. Consider thermal insulation, heat transfer etc.　　4. Design signal conditioning circuitry to convert sensor output to standardized signals compatible with instruments like amplifiers, filters, transmitters etc.　　5. Develop calibration curves and apply compensation algorithms in microcontroller if required for high accuracy.　　6. Implement temperature scaling and linearization if needed in firmware or hardware.　　7. Add optional features like remote sensor with transmission line, displays, alarms, microprocessor integration.　　8. Test prototype under standard reference temperatures for calibration, accuracy, repeatability.　　9. Enhance product through validation testing under field conditions, certifications.　　10. Prepare design documentation for manufacturing.　　What is the range of a temperature sensor?Temperature sensors can measure a wide range of temperatures based on the sensing technology and construction. Some common measurement ranges are:　　• Thermocouples: -250°C to 1350°C　　• RTDs: -200°C to 650°C　　• Thermistors: -55°C to 150°C　　• Integrated circuits: -55°C to 150°C　　• Infrared sensors: -50°C to 500°C　　Special types of sensors further extend the limits to measure very low cryogenic temperatures below -200°C for applications like liquified natural gas plants, high energy physics labs.　　Similarly, special metallurgical thermocouples and optical pyrometer sensors go up to 3000°C for processes like steel making, glass welding.　　ConclusionAn accurate and reliable temperature sensor is fundamental for process and quality control across major industries due to its role in monitoring, regulating and safety applications.　　Understanding sensor types, principles, design and selection based on application demands is key.　　Advancing technologies are continuously improving sensing capabilities to wider ranges, higher precisions and intelligent outputs.　　As temperature measurement takes a more vital role, evolution of sensors will keep pace with the emerging trends.

NOVOSENSE launches automotive-grade temperature and humidity sensor NSHT30-Q1, driving the development of automotive intelligence

　　NOVOSENSE's new automotive temperature and humidity sensor NSHT30-Q1 is a relative humidity (RH) and temperature sensor based on CMOS-MEMS.　　NSHT30-Q1 integrates a complete sensor system on a single chip, including a capacitive RH sensor, CMOS temperature sensor and signal processor, and an I2C digital communication interface. It is designed in DFN package with Wettable Flank, and the product size is only 2.5mm×2.5mm×0.9mm. The I2C interface communication mode, small and reliable package, and wider operating temperature range make NSHT30-Q1 well suited for automotive applications.　　With the development of automotive intelligence, in-vehicle systems increasingly rely on judgment of the surrounding environment to make decisions. To achieve real-time control and autonomous operation, these systems need to capture necessary information with high-precision sensor products that can respond quickly.　　Take the automotive 5-in-1 sensor as an example. It uses the built-in temperature and humidity sensor to detect the temperature and humidity on the inside of the front windshield, and then calculates the dew point temperature. In this way, the air conditioning system can adjust the temperature inside the vehicle, the air outlet mode, the internal and external circulation, and other functions according to these signals, effectively reducing the humidity inside the vehicle and achieving the defogging function.　　At the same time, the lidar cannot work without support from the temperature and humidity sensor. The temperature and humidity sensor monitors the radar's operating temperature and humidity to ensure that it operates in a suitable operating environment to avoid performance degradation due to excessive temperature. The temperature and humidity sensor can also detect relative humidity to monitor whether the lenses of the lidar and camera module are broken, thereby avoiding damage to internal optical components caused by humid environments and ensuring vehicle driving safety.　　NOVOSENSE's NSHT30-Q1 is an automotive single-chip integrated temperature and humidity sensor with high reliability, high precision and low power consumption, suitable for various automotive applications, such as automotive HVAC control modules and battery management systems. By helping vehicles achieve more efficient and stable system performance, it provides strong support for the development of automotive intelligence.　　In addition, NSHT30-Q1's I2C interface features two selectable I2C addresses with communication speed up to 1 MHz and supports a wide supply voltage range of 2.0V~5.5V for various applications. Also, with programmable interrupt thresholds, alarms and system wake-up can be provided without the need for a microcontroller to continuously monitor the system.　　Performance parameters of NSHT30-Q1　　· Relative humidity (RH) sensor　　- Operating range: 0%~100　　- Precision: ±3% (typical)　　· Temperature sensor:　　- Operating temperature range: -40°C~125°C　　- Precision: ±0.3°C (typical)　　· Relative humidity and temperature compensated digital output　　· Wide supply voltage range: 2.0V~5.5V　　· I2C digital interface with communication speed up to 1 MHz　　- Two selectable addresses　　- Data protection with CRC　　· Low power consumption: average current of 2.5µA　　· 8-Pin Wettable Flank DFN package　　· AEC-Q100 compliant

novosns：Sensors improve the energy efficiency and environmental performance of central air conditioners through precise temperature, humidity, pressure, and current measurement

　　With the improvement in people's living standards and the growing demand for a more comfortable living environment, China's central air conditioning market has maintained relatively stable growth. Temperature and humidity, pressure, and current sensors with high-precision detection capability are critical to the various functions of central air conditioning. As a manufacturer of high-performance, high-reliability analog and mixed-signal chips, NOVOSENSE offers a wide range of sensor and analog IC solutions for central air conditioning applications.　　Development trends and new requirements for central air conditioning　　According to statistics, in the first half of 2023, in China's central air conditioning sales, multi-connected systems accounted for approximately 51%, continuing to rank first in the market. The reason why multi-connected systems are favored by the market mainly lies in their low installation cost, flexible applications, and high energy efficiency. For this reason, some well-decorated homes have also begun to standardize on this type of air conditioning.　　Commercial central air conditioners adopt a one-to-many architecture, in which an outdoor unit drives multiple indoor units. Each indoor unit has a corresponding line controller, which can automatically adjust the air outlet, airflow, and cooling and heating power through the feedback of temperature and humidity to maintain a comfortable indoor temperature.　　The development trend of multi-connection technology is mainly reflected in two directions. One is energy saving and noise reduction: outdoor units and even indoor units have frequency conversion capabilities, which can reduce noise by increasing the frequency while achieving low standby power consumption. The other is better comfort and improved environmental performance: meeting specific requirements for airflow, temperature and humidity control while reducing the damage of refrigerant leakage to the natural environment to ensure effective air conditioning.　　· NOVOSENSE's sensor products can exactly meet the above trend requirements. These products include temperature and humidity sensors and pressure sensors that meet comfort and environmental performance requirements, magnetic current sensors that ensure normal operation of outdoor units, and various analog IC products.　　NOVOSENSE offers comprehensive sensor solutions for central air conditioning applications　　The temperature and humidity sensor is used to detect the ambient temperature and humidity to control the airflow from the air outlet and balance the ambient humidity for improved comfort.　　NSHT30 is a temperature and humidity sensor with very small size and very high accuracy. It adopts a 2.5mm×2.5mm small package (LGA and DFN options). The MCU reads the temperature and humidity data through the I²C interface of the sensor. Temperature and humidity measurements are from -40°C to 125°C and from 0 to 100%, which can basically cover all temperature and humidity ranges.　　The advantage of NSHT30 is, first of all, the response time. The acquisition time of temperature and humidity is only 2s and 6s, respectively. Its accuracy is also higher than other similar products in the market. The chip calibration before leaving the factory can ensure high accuracy requirements. Under the condition of 0~50°C, the error of NSHT30 can be controlled at ±0.3°C (typical value); and under the condition of 50% relative humidity, the error can be controlled at ±3% to meet the accuracy requirements of air conditioning.　　The pressure sensor is usually placed on the outdoor unit or refrigerant transmission pipe to detect refrigerant leakage and refrigerant pressure, ensuring effective air conditioning while achieving environmental performance.　　NSPAS3 is an integrated absolute pressure sensor for refrigerant leakage pressure detection in air conditioners. Its operating temperature is from -40°C to 130°C, and its internally integrated temperature compensation circuit can achieve ±1% control accuracy in the range of 0~85°C and ±1.5% control accuracy in the range of -40°C to full temperature.　　NSPAS3 is compatible with the pressure test range of 10kPa~400kPa and can detect refrigerant leakage pressure. The standby power consumption of this product is less than 3mA, and the response time is within 0.8ms. In addition, the chip package is coated with anti-corrosion jelly glue, which can prevent some corrosive gases from damaging the chip package.　　NSC2860x is a capacitive pressure transmitter signal processing ASIC solution. It can detect the refrigerant pressure (3~5MPa) in the air conditioning compressor. The chip integrates various digital components such as PGA, ADC, MCU and various interfaces. It has a very high degree of integration and can convert the monitored pressure into a digital signal for processing by the MCU. NSC2860x also integrates a 4-20mA loop power supply, which enables longer distance transmission to meet the communication distance requirements between the pressure sensor and the MCU main control board in the refrigerant system.　　The magnetic current sensor is generally placed in the outdoor unit and is mainly used to monitor the current of the outdoor unit, such as PFC current or phase current of the air conditioning compressor motor. It achieves tracking feedback by collecting system current signals to ensure normal operation of the system.　　NSM2019 is an integrated Hall current sensor, mainly used to detect the motor current or PFC current of the air conditioner. The MCU reads the current value through the VOUT pin. It integrates the reference voltage and OCP (overcurrent protection) internally, eliminating the need for some peripheral devices such as comparators or op amplifiers. This product covers a range of 20A~200A, which can meet the power requirements of commercial air conditioners from several kilowatts to one hundred kilowatts.　　NSM2019 has an accuracy of ±2% and can guarantee accuracy over the full temperature range. Its isolation withstand voltage is up to 5,000V, the creepage distance is up to 8.2mm, and it can withstand 20kA surge current. Its input bandwidth is as high as 320K, which can meet the bandwidth requirements of current detection. Due to the small internal resistance, the heat output of the chip is also small.　　Other analog IC solutions for central air conditioning applications　　In addition to sensors, NOVOSENSE offers many analog IC product solutions. Analog ICs are mostly used in outdoor units. The topology of the outdoor unit determines that the 220V mains power needs to be rectified by PFC to approximately 400VDC, which then feeds the bus voltage of the two motors. The motor is directly driven by IGBT or IPM. The MCU that drives the IGBT is usually placed at the low voltage end, so it is necessary to use an isolated driver to rotate the motor. As a result, many isolated driver products are required. At the same time, the current and voltage must be monitored. The PLC also needs to collect the voltage and current, so op amplifier products are also used.　　The outdoor unit and the indoor unit communicate through 485 or CAN bus. Since the two generally do not share a common ground, some isolated interfaces are also needed. NOVOSENSE provides digital isolator products that convert high voltage to low voltage to power MCUs. The power supply is usually converted from high voltage to low voltage by flyback power supply, then converted to 5V by DC-DC, and then converted to 3.3V by LDO to power other chips.

ROHM's New Zero-Drift Op Amp with High Accuracy Regardless of Temperature Changes

　　ROHM has developed a zero-drift operational amplifier (op amp) - the LMR1002F-LB. It is designed for industrial and consumer electronics devices and minimizes both input offset voltage and input offset voltage temperature drift. Capable of accurately amplifying output signals from sensors installed in various measurement devices, this new op amp is ideal for current sensing applications such as power control inverters and temperature/pressures/flow/gas detectors.　　As automotive and industrial equipment become more sophisticated and application control requirements are more precise, environmental sensors are increasingly being used to quantify temperature, pressure, and gas concentrations such as carbon dioxide to foster a sustainable society. However, sensor signals are so small that amplification is necessary, and if a general op amp with 1mV offset voltage is used to amplify the sensor signal by a factor of 1,000, for example, the offset voltage also increases by this amount - resulting in a voltage error of 1V (1,000mV) in the signal output. At the same time, input offset voltage temperature drift, which varies according to temperature and time, is difficult to compensate for.　　In response, ROHM developed a zero-drift op amp that addresses these problems by leveraging proprietary analog circuit technology - cultivated over many years. The LMR1002F-LB is ROHM’s first zero-drift op amp using the chopper method. In contrast to conventional low-offset op amps featuring a typical input offset voltage of 150µV (Max.), ROHM’s new product limits input offset voltage to just 9µV (94% lower). This eliminates the need for peripheral components or software to adjust the input offset voltage, reducing both design person-hours and costs. On top, input offset voltage temperature drift is just 0.05µV/°C (Max.) in the operating temperature range of -40°C to +125°C - the lowest among ROHM’s op amps. Enabling accurate amplification of measured sensor signals without being affected by environmental changes such as temperature contributes to high accuracy control of industrial equipment in factories. This, coupled with a wide supply voltage range of 2.7V to 5.5V and rail-to-rail input/output, make it ideal for a variety of industrial applications.　　Going forward, ROHM will continue to improve the performance and expand its lineup of zero-drift op amps. Moreover, ROHM will work to improve the performance of op amp lineups by reducing noise and offset - while increasing power savings, and expand the power supply voltage range demanded in the automotive and industrial equipment markets. The overall goal: contributing to solving social issues through higher accuracy application control.      Product Lineup　　Application Examples　　• Industrial equipment: Power control inverters, photovoltaic inverters, storage battery monitoring, pressure gauges, flow meters, temperature controllers, gas detectors, etc.　　• Consumer appliances: Refrigerators, washing machines, air conditioners, etc.　　Online Sales Information　　Sales Launch Date: December 2023　　Pricing: $8.0/unit (samples, excluding tax)　　The product will be offered at other online distributors as it becomes available.　　■Product Information　　Applicable Part No: LMR1002F-LB　　Terminology　　Input Offset Voltage　　Refers to the error voltage that occurs between the input terminals of an op amp.　　Input Offset Voltage Temperature Drift　　The fluctuation in input offset voltage caused by a rise/fall in temperature. The smaller this value is the higher the op amp accuracy. Zero-drift op amps automatically compensate for input offset temperature drift.　　Chopper Circuit　　A circuit configured to detect the offset voltage generated inside an op amp and automatically correct it via digital circuit control. This cancels offset voltage by feeding back the offset voltage stored as capacitance in the circuit using a voltage-current conversion circuit.　　Rail-to-Rail Input/Output　　A circuit format that allows the input and output voltages of an op amp to accommodate the entire supply voltage range. The supply voltage in this case is called a Rail.

ROHM’s New High Power 120W Laser Diode for LiDAR: Increasing Measurement Range by Reducing Wavelength Temperature Dependence by 66%

　　ROHM has developed a high-power laser diode - the RLD90QZW8. It is ideal for industrial equipment and consumer applications requiring distance measurement and spatial recognition.　　In recent years, LiDAR is being increasingly adopted in a wide range of applications that require automation - including AGVs (Automated Guided Vehicles), robot vacuums, and autonomous vehicles - where it is necessary to accurately measure distance and recognize space. In this context, there is a need to improve the performance and output of laser diodes when used as light sources to increase detection distance and accuracy.　　To meet this demand, ROHM established original patented technology to achieve a narrower emission width that contributes to longer range and higher accuracy in LiDAR applications. In 2019, ROHM released a 25W laser diode RLD90QZW5 followed by a 75W laser diode RLD90QZW3 in 2021. In response to the growing market demand for even higher output, ROHM developed a new 120W laser diode.　　The RLD90QZW8 is a 120W infrared high output laser diode developed for LiDAR used in distance measurement and spatial recognition in 3D ToF systems. Original device development technology allows ROHM to reduce the temperature dependence of the laser wavelength by 66% over general products, to just ⊿11.6nm (Ave. 0.10nm/°C). This makes it possible to narrow the bandpass filter while extending the detection range of LiDAR. At the same time, a uniform light intensity of 97% is achieved over the industry's smallest class* of emission width of 270µm, representing a range of 264µm that contributes to higher resolution. Additional features that include high power-to-light conversion efficiency (PCE) enables efficient optical output that contributes to lower power consumption in LiDAR applications.　　A variety of design support materials necessary for integrating and evaluating the new product is available free of charge on ROHM’s website that facilitate market introduction. In order to drive laser diodes with high nano-second order speed required for LiDAR applications, ROHM developed a reference design available now that combines ROHM’s 150V EcoGaN™ HEMT and gate drivers.　　ROHM has also acquired certification under the IATF 16949 automotive quality management standard for both front-end and back-end processes at its manufacturing facilities. As a result, product development of laser diodes for automotive applications (AEC-Q102 compliant) is underway, with commercialization planned by the end of 2024.　　Application ExamplesConsumer: Robot vacuums, Laser rangefinders　　Industrial: AGVs (Automated Guided Vehicles), service robots, 3D monitoring systems (sensors for human/object detection)　　and more...　　Support PageA broad range of design data is available on ROHM’s website free of charge, including simulation (SPICE) models, board development data, and application notes on drive circuit design necessary for integration and evaluation that supports quick market introduction.　　Reference DesignsReference designs for LiDAR incorporating these new products together with ROHM’s 150V EcoGaN™ and high-speed gate driver (BD2311NVX series) are now available on ROHM’s website.　　Reference Design Part Nos.　　・REFLD002-1　　(120W High Power Laser Diode [RLD90QZW8] built-in)　　・REFLD002-2　　(75W High Power Laser Diode [RLD90QZW3] built-in)　　EcoGaN™ is a trademark or registered trademark of ROHM Co., Ltd.　　Online Sales InformationSales Launch Date: September 2023　　Pricing: $30.0/unit (samples, excluding tax)　　Online Distributors: DigiKey, Mouser and Farnell　　The product will be offered at other online distributors as they become available.　　Target Product: RLD90QZW8-00A　　Online Distributors　　TerminologyLiDAR　　Short for Light Detection and Ranging, a type of application that uses ToF (Time of Flight) system (comprised of a light source and ToF or image sensor) to sense ambient conditions.　　3D ToF System　　An abbreviation for Time of Flight, a spatial measurement system which, as its name implies, measures the flight time of a light source.
