The MQ5 gas sensor module is highly useful for gas leakage detection at home or industry. The sensor module can detect hydrogen, carbon monoxide, methane and LPG. It is highly sensitive and responding time is very fast. Depending on the requirements of sensitivity, the sensor can be adjusted with a Potentiometer.

MQ5 is an analogue output sensor which is commonly used as LPG, Natural gas sensor in MQ sensor series. It is a widely used Gas Sensor in verious sectors. The output voltage of the gas sensor increases if the concentration of gas increases. The sensitivity of the sensor is adjustable by the Potentiometer. The MQ5 who is arduino compatible.

The working voltage of MQ5 gas sensor is 5 volt DC and it draws around 800 mw . This sensor is capable of detecting LPG, natural gas , town gas concentrations anywhere from 200 to 10000ppm.
