Pololu Methane Gas Sensor MQ4
The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. For example, the sensor could detect if someone left a gas stove on but not lit. The sensor can operate at temperatures from 10 to 50°C and consumes less than 150 mA at 5 V. Please read the MQ4 datasheet (161k pdf) for more information about the sensor.
