Product Description


The sensor module FC-22 v1.3, with MQ-2 gas sensor works thank to a sensitive material SnO2, which is with lower conductivity in clean air. When the target combustible gas exist, the sensors conductivity is higher along with the gas concentration rising. Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal. MQ-2 gas sensor for gas, propane, hydrogen of high sensitivity, natural gas and other combustible vapours detection is also very satisfactory. The sensor can detect a variety of flammable gas, is a low-cost sensors for a variety of applications.


Technical specification:
