MQ137 Ammonia NH3 Gas Sensor Module

20211012 · The MQ137 is basically an Ammonia (NH₃) gas sensor. The sensor includes tin dioxide as its sensing element. The SnO2 (tin dioxide)has lower conductivity in pure air. When the air has ammonia, the conductivity of the sensor gets higher. A simple device makes measuring this change in conductivity and turning it into obvious data.


MQ137 Ammonia Gas Sensor ... Microcontrollers Lab

The MQ137 is an ammonia gas sensor which detects the presence of ammonia gas. As the concentration of N gas rises in the air, the conductivity of the sensor tends to become higher. Using a circuit, you can convert this change in conductivity to the output value which indicates the concentration of a gas. Along with ammonia gas…
