Description

Sensitive material of MQ137 gas sensor is SnO2, which with lower conductivity in clean air. When NH3 gas exists, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ137 gas sensor has high sensitivity to NH3 gas, also can monitor organic amine such as trimethylamine, cholamine well. It can detect kinds of gases including ammonia and is a kind of low-cost sensor for kinds of applications. Application It is widely used in civil odor gas NH3 ammonia alarm, industrial NH3 hazardous gas leakage alarm, portable NH3 gas detector. Features It has good sensitivity to NH3 gas in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc.
