A Small D.I.Y. Methane, Butane and Liquid Petroleum Gas Sensor that offers digital and analog outputs for Microcontrollers.
This is a small Do It Yourself kit that requires soldering to get it operational. This sensor comes with the MQ2 sensor that will detect Methane, Butane and Liquid Petroleum Gas.
This module also has a buzzer and LED to indicate when the sensor is triggered. Alternatively you have some header pins on the board that will provide either analog or digital signal to your microcontroller of choice.
