Sensitive material of MQ-2 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.
MQ-2 gas sensor has high sensitity to LPG, Propane and Hydrogen, also could be used to Methane
and other combustible steam, it is with low cost and suitable for different application.
Characters of the sensor
*Good sensitivity to Combustible gas in wide range
* High sensitivity to LPG, Propane and Hydrogen
* Long life and low cost
* Simple drive circuit
Applications
Domestic gas leakage detector
* Industrial Combustible gas detector
* Portable gas detector
MQ2 will be applied to the beginning of the machine where functional as sensor. when the sensor operate, the output will be connected to the control system to operate the others system.
The industrial LPG gas leak detector and smoke detectors are highly sensitive devices designed to quickly detect the presence of LPG or smoke leaks in industrial settings, ensuring prompt response and preventing potential hazards.
