Descrizione completa
The MQ-137 is an Ammonia (NH₃) gas sensor from Winsen. The sensing element is SnO2 which has lower conductivity in clean air. When NH₃ (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.
