for indoor combustible gas alarm
Application:
For alarm/monitorProduct characteristics:
Long life MQ-G5 is in accordance with the New National Standard of 《GB15322.2-2019》and the Housing and Construction Ministry Standard of CJ/T347-2010 . It’s sensitive to natural gas, liquefied gas and town gas.
Sensitive material of MQ-G5 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-G5 gas sensor has high sensitivity to butane, propane, methane and can detect methane and propane at the same time. It also can detect kinds of flammable gases, especially LPG(Propane). It is a kind of low–cost sensor for many applications.
It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector.
It has good sensitivity to flammable gas (Especially Propane) in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc.
