Product Description:
MQ137 Ammonia Sensor For Household Ammonia Alarm
Features:
Gas sensitive material used in the MQ137 gas sensor is tin dioxide (SnO2), which has a low conductivity in clean air. When there is ammonia in the environment of the sensor, the conductivity of the sensor increases with the increase of the concentration of ammonia in the air. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the concentration of that gas. The MQ137 gas sensor has a high sensitivity to ammonia and is ideal for monitoring other organic amines (such as trimethylamine, ethanolamine, etc.). This sensor can detect a wide range of ammonia containing gases, making it a low-cost sensor suitable for a variety of applications.
Main application
It is widely used in household ammonia alarm, industrial ammonia leak alarm and portable ammonia detector
