MQ-5 LPG, Smoke Sensor

The MQ-5 LPG, Smoke Sensor is useful for gas leakage detection (in home and industry). It is suitable for detecting LPG, i-butane, methane, alcohol, Hydrogen, smoke and so on.Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer. The output voltage from the Gas sensor increases when the concentration of gas increases. Sensitivity can be adjusted by varying the potentiometer.
