MQ-2 Smoke and Flammable gas


MQ-2 gas sensor has high sensitity to smoke and flammable gas. Long life and low cost. Simple drive circuit. Use LM393 driver;

Application :
Sensitive material of MQ-2 gas sensor is SnO2which with lower conductivity in clean air.When the target combustible gas existThe sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuitConvert change of conductivity to correspond output signal of gas concentration.MQ-2 gas sensor has high sensitity to LPGPropane and Hydrogenalso could be used to Methane and other combustible steamit is with low cost and suitable for different application.
