MQ-4 sensor module

MQ-4 methane gas sensor, nature gas sensor, LNG gas detection sensor with long lifespan and low price. The sensitive material of the MQ-4 gas sensor is SnO2, which has 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 to the output signal of gas concentration through a simple circuit. MQ-4 gas sensor has high sensitivity to methane, also has anti-interference to alcohol and other gases.
Target Gas: Methane/CH4/ LNG
Detection range: 300～10000ppm
Application:Domestic gas leakage alarm, Nature Gas Detection Gas Sensor/ Semiconductor Gas Sensor
