Air Contaminants Sensor, For Ventilation Control

This is a very high sensitive gaseous air contaminant detector with a sensing element made of metal oxide semiconductor with an integrated Heater. The sensor can detect very low concentration of hydrogen and carbon monoxide gases present in air such as ’s smoke.The measure of the gas concentration corresponds to change in output signal with the change in conductivity.

The sensor require common voltage input for the two units namely for sensing element and heater.
