Description: MQ-2 Gas And Smoke Sensor

MQ-2 MQ2 Smoke LPG Butane Hydrogen Gas Sensor Detector MQ2 Smoke LPG MQ-2 Butane Hydrogen Propane Combustible Gas Detection Sensor For Arduino Electronics Project DIY

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 electro circuit, Convert change of conductivity to correspond output signal of gas concentration. MQ-2 gas sensor has high sensitivity 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.
