MQ137 Ammonia Detection NH3 Gas Sensor Module

MQ - 137 NH3 Gas Sensor Module

The MQ137 sensor is a gas sensor module specially designed to detect and sense gases like ammonia (NH3) and carbon monoxide (CO). The MQ-137 gas sensor module is a device that can detect the presence of ammonia (NH3) gas in the air. It is commonly used in applications such as air quality monitors, industrial control systems, and agricultural environments. The MQ-137 sensor operates by using a chemical reaction between the ammonia gas and conductive metal oxide to produce a current.

The magnitude of the current is proportional to the concentration of ammonia gas in the air. The sensor can be used to detect ammonia gas concentrations in the range of 0-1000ppm. Ammonia is a toxic gas that can be harmful to humans at high concentrations. It is recommended to use the MQ-137 sensor with caution and to take appropriate safety measures when working with it.

Detect or measure gases like NH3 or CO
Air quality monitor
Gas leak alarm
