MQ5 Gas Sensor Module 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. Connections: VCC - 2.5V ~ 5.0V GND - ground Aout - MCU.IO (analog output) Dout - MCU.IO (digital output) Heater Voltage: 5.0V Power Supply: 5 Volts Interface Type: Analog & Digital Working Current: 150mA Item Weight: 10.0 grams High sensitivity to LPG, natural gas, town gas. Small sensitivity to alcohol, smoke
