The MQ-137 is an Ammonia (NH₃) petrol sensor from Winsen. The sensing element is SnO2, which has lower conductivity in clean air. When NH₃ (Ammonia) petrol exists, the sensor’s conductivity gets higher as the petrol concentration rises. A simple circuit makes measuring this change in conductivity and turning it into data fairly straightforward, but it does require some calibration.
