Ammonia Gas Sensor - MQ-137

Sparkfun Electronics  |  SKU: 3843
£21.46 £42.92
Tax included (UK orders only), shipping and discounts calculated at checkout.
DESCRIPTION

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 along with the gas concentration rising. A simple circuit makes measuring this change in conductivity and turning it into data fairly straightforward, but does require some calibration.

Note:

  • PCB is not included.
