Winsen MQ137 Semiconductor Sensor for Ammonia Description:
Sensitive material of MQ137 gas sensor is SnO2, which with lower conductivity in clean air. When the
target combustible 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.
Character Configuration
* Good sensitivity to Ammonia
* Long life and low cost
* Simple drive circuit
Application
* Domestic Ammonia detector
* Industrial Ammonia gas detector
* Portable gas detector
