Commercialized high precision agricultural CO2 sensors with superior long-term stability

　　Murata Manufacturing Co., Ltd. (hereinafter "Murata") has commercialized "IMG-CA0012-12" (hereinafter "this product"), a case and cable type CO2 sensor. This high precision product primarily connects to environment measurement equipment in agricultural greenhouses and stably measures CO2 concentration. Through linkage with photosynthesis accelerators, this product will contribute to improving crop quality and increasing yield. Additionally, it improves energy efficiency by injecting an optimal amount of CO2 at an optimal timing. Mass production and supply for this product has begun in Hakui Murata Manufacturing.

　　In the field of agriculture, increased yield and quality improvement per unit area are required since there is a reduction in yield and decline in quality due to global warming as well as a drop in agricultural worker population. Technology for accelerating crop photosynthesis using CO2 application is an effective means of addressing these challenges. Furthermore, due to the recent increase in energy costs, effective CO2 application based on environmental data measurements is crucial. As a result, high-precision CO2 sensors, which offer long-term stability, require no calibration, and are resistant to malfunction, play a crucial role in photosynthesis accelerator technology.

　　This product is equipped with an automatic calibration function that runs on our unique calibration curve algorithm and dual wavelength (for measurement and reference) NDIR*1. Therefore, atmospheric calibration is not required. This ensures high precision and long-term stability, making it maintenance-free. Furthermore, its case and cable type design enhances user handling and ease of installation.

　　Specifications

　　CO2 sensors were installed in greenhouses and were used for a year for tomato cultivation and 2 years for rose cultivation. After use, CO2 concentration characteristics and temperature characteristics were evaluated.

　　It was discovered that CO2 concentration differences were minimal even when they were used for a long period of time in actual fields.
