Soldered 333113 Ammonia sensor MQ137 breakout
Description
The MQ137 gas sensor detects the presence of ammonia (NH3). While it is most effective with liquids, it also performs well with gases, making it versatile for various applications.
The sensor requires minimal time to heat up for optimal functioning.
The breakout board operates with both digital (DO) and analog (AO) signals. Digital output is obtained by setting the threshold values using the potentiometer, while the analog output varies based on the gas intensity around the sensor.
