MQ137
MQ137 Semiconductor Sensor for Ammonia
Sensitive material of MQ137 gas sensor is Sn O2, which with lower conductivity in clean air. When the target bustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
MQ137 gas sensor has high sensitity to Ammonia, also to other organic amine. The sensor could be used to detect different gas which contains Ammonia, it is with low cost and suitable for different application.
