The MQ137 gas sensor is a sensitive material, SnO2, which has lower conductivity in clean air. When the target combustible gas exists, the conductivity of the sensor increases the higher the gas concentration increases. Please use a single electric circuit. Convert the change in conductivity to match the gas concentration output signal. The MQ137 gas sensor has a high sensitivity to ammonia, as well as other organic amines. The sensor could be used to detect different gases containing ammonia, it is economical and suitable for different applications. Specifications: Model Number: MQ137 Sensor Type: Semiconductor Standard Encapsulation: Bakelite (Black Bakelite) Detection Gas: Ammonia Concentration: 5-500ppm (Ammonia)
