Carbon Dioxide Module GS302M-S
The GS302M-S carbon dioxide sensor module based on NDIR principle, is widely used to detect the carbon dioxide in the air. It outputs the carbon dioxide concentration through UART or PWM interface. The GS302M-S module has a built-in thermistor for temperature compensation. It has been calibrated in Multi IR’s humidity and temperature controlled facility, so it can be used directly in the testing instruments and monitoring equipment.
