Product Description

Gas sensor registers the presence of ammonia gas (NH3). It registers gases the best while they are in the liquid form, but since we cannot find them in that state that often, it measures a good concentration of substances in a gaseous state. It takes a short time to heat up in order to work correctly.

 

The breakout board works with both digital (DO) and analog signals (AO). The digital output is obtained by setting a threshold value with a potentiometer. The analog output will differ depending on the intensity of the gas.
