A wireless CO2 sensor suitable for use in IAQ systems consists of four major building blocks, a CO2 sensor, microcontroller, low power radio module, and a power source. Non-dispersive infrared CO2 sensors work by illuminating the gas using a filtered incandescent light source and measuring the absorption using a light detector.

Built-in temperature compensation; and it has UART output and PWM output.
A sensor that is ideal for measuring indoor CO2 levels for indoor air quality will not work to measure concentrations used in fire suppression testing. One OEM might want I2C protocols, while another individual prefers UART. Some applications require the use of a sampling sensor instead of diffusion. Furthermore, understanding your application and its requirements is vital in selecting the ...
