Description

This analogueue gas sensor has a small heating element with an electronic-chemical sensor. It is intended for indoor use. It can be used to measure air pollution. These include benzene (C6H6), ammonia (NH3), sulphide, smoke, other air pollution. The threshold setting (small potentiometer on the sensor module) therefore makes an ideal application for reporting gas leaks or triggering a gas alarm.
