British Clairair High-Resolution Infrared Carbon Dioxide Sensor (NDIR CO2 Sensor)
The Prime3 sensor utilizes 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.
