Description This MQ5 gas sensor is used in gas leakage detection, and suitable for home and industrial equipments for LPG, natural gas, coal gas detection and monitoring. The sensitive material used in the MQ5 gas sensor is SnO2, which has lower conductivity in clean air. When the target combustible gases exist in the atmosphere, sensor’s conductivity increases with the gas concentration. MQ5 Gas Sensor Specifications: Item Weight: 10.0 grams Heater Voltage: 5.0V Power Supply: 5 Volts Interface Type: Analog & Digital Working Current: 150mA DOUT: TTL output AOUT: Analog output Product Description To use the Sensor Module, you have power the device with 5V supply and the Power LED will start to glow. You should give it some time for its preheating period before start reading the output. While measuring the gas present, the Output LED will glow in a specific concentration of the gas. You can change it by using the potentiometer. Else you can also use the Analog Output to see how your program reacts to different concentrations of gases present.
