Description:
The MQ-4 Methane Gas Detection Sensor Module detects Methane gas in the surrounding air. The concentration of methane is output as an analogue voltage reading. This sensor can detect concentrations between 300 – 10000ppm and is suitable for portable gas detectors and home safety automation systems.
The module requires two (2) different voltage inputs to operate. Heater voltage should be 5V (AC or DC) and Loop Voltage should be less than 24VDC.
Please read the MQ4 datasheet for more info about the sensor.
