Description

This analogueue gas sensor has
a small heating element with
an electronic-chemical sensor.
It is
suitable for indoor use.

Measurable substances: Carbon monoxide (CO)

The sensitivity of the sensor can be adjusted via a potentiometer. For example, you can set a threshold that triggers a gas alarm.
