Highly sensitive so2 Charging Wireless Sensors

Highly sensitive so2 Charging Wireless Sensors

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. However, the power consumed using this type of CO2 sensor is too high to make it usable in a portable, or low power application.
