MQ-137 NH3 Gas Sensor Module for Ammonia, Carbon monoxide Detector 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 0-1000 ppm. 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. Applications: Detect or measure Gases like NH3 or CO Air quality monitor Gas leak alarm Safety standard maintenance Maintaining environmental standards in hospitals
- The gas sensor module has a signal output indicator indication.
- The analog output increases with increasing concentration, and the higher the concentration, the higher the voltage.
