MQ-2 Semicon Ductor Sensor For Flammable Gas Has Good Sensitivity To Propane For Widely Used In Domestic Gas Leakage Alarm
Profile :
Sensitive material of MQ-2 gas sensor is SnO2,which with lower conductivity in clean air. When the target flammable gas exist, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ-2 gas sensor has high sensitivity to propane and smoke, also can detect the natural gas and other flammable steam well. It is with low cost and suitable for different applications of detecting kinds of flammable gases.
Features:
It has good sensitivity to propane, smoke &etc in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc
Main Applications:
It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector.
