NDIR Gas Sensor

The NDIR gas sensor can measure the CO2 gas concentration through the change of the resistance value of the internal thermistor. The product is packaged in a TO-46 metal socket and a narrow bandpass filter for the CO2 gas band. The sensor integrates electronic components such as thermopile chips and thermistor, with high reliability and high sensitivity. The sensor is designed for indoor use.

In addition, we welcome any challenges and needs for customized applications
