Ultra-Low Power, High Performance Ambient CO2 Sensor - COZIR from CO2Meter

The COZIR ultra low power (3.5mW), high performance CO2 sensor is designed to suit battery operation, portable devices and measuring ambient CO2 for HVAC control.

The sensor is based on infrared LED and detector technology and innovative optical designs, and hence offers the lowest power NDIR sensor commercially available.

CO2Meter provides optional temperature and humidity models as well.

The sensing method used for CO2 measurement is NDIR with gold-plated optics, and the sample method used is diffusion.
