The MQ-137 is an Ammonia (NH ) gas sensor from Winsen. The sensing element is SnO2 which has lower conductivity in clean air. When NH (Ammonia) gas exists the sensor s conductivity gets higher as the gas concentration rises. A simple circuit makes measuring this change in conductivity and turning it into data fairly straightforward but it does require some calibration.For easy Solderability use our Gas Sensor Breakout Board.
