The MQ-6 LPG – Isobutane – Propane Gas Sensor is a semiconductor gas sensor that detects the presence of LPG, Isobutane, and Propane gas at concentrations from 100 ppm to 10,000 ppm, a range suitable for detecting gas leaks. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.The MQ-6 LPG – Isobutane – Propane Gas Sensor detects the concentration of gas in the air and outputs its reading as an analog voltage. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.
