Order before 12.00PM
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 straight-forward, but does require some calibration.
Main Features:
- Main Chip: MQ137
- Gas Sensitivity: Ammonia (NH3) and Carbon Monodioxide (CO)
- Working voltage: 5v
- Concentration range: 10 to 300ppm
