MQ-4 Methane Gas Sensor Module
KSh 500.00
MQ-4 Methane Gas Sensor Module detects the concentration of methane gas in the air then outputs its reading as an analog voltage. The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. For instance, the sensor could detect if someone left a gas stove on but not lit. It can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.
