MQ-6 LPG - Isobutane - Propane Gas Sensor detects the concentration of gas in the air and ouputs its reading as an analog voltage. The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.
This module provides both digital and analog outputs. Threshold level for digital output can be easily adjusted using the preset on the board. MQ-6 sensor module can be easily interfaced with Microcontrollers, arduino and etc.
