UK Clairair high-resolution infrared carbon dioxide sensor (NDIR CO2 sensor)
The Prime2 sensor uses NDIR technology to detect CO2 gas concentration. Inside the sensor, there is an infrared light source, a dual-element infrared detector, a unique optical waveguide that allows gas to diffuse in, and an ARM7 core microprocessor, with output voltage independent of power supply polarity. The high-resolution infrared carbon dioxide sensor Prime2 can be set to linear voltage output, full range 0.4V-2.0V referenced to the negative terminal of the power supply, or set to catalytic
