Detect the presence and concentration of ammonia (NH3) gas in the ambient air using the MQ-137

Ammonia Click is an ammonia detection (NH3) sensor, based on the MQ-137 gas sensor. This gas sensor has a sensitive layer made of SnO2, which changes its resistance when exposed to ammonia. The sensor can sense NH3 concentration in the range of 5 ppm to 200 ppm. The Click board™ has a trimmer potentiometer, used to adjust the sensitivity and offset of the MQ-137 sensor.

It can be used in different Ammonia concentration detectors for air quality control, or for gas leak detection.
