Q & A

MQ-4 Methane CNG Gas Sensor Module detects Methane, Butane, and LPG. Due to its high sensitivity and fast response time, measurements can be taken immediately. The sensor’s sensitivity can be adjusted using the potentiometer.

The module features an MQ-4 gas sensor that delivers a direct analog output.
It also includes an LM393 comparator IC and an adjustable potentiometer for setting a digital output threshold.

Additionally, the module features a power indicator LED, a digital output status LED, and a convenient header for easy connection.
