MQ-4 Natural Gas Sensor Module For Methane(CNG) gas Detector Module LEDs Each relay has all threeMQ 4 Natural Gas Sensor Module This is a straightforward MQ 4 Gas Sensor Module that detects the presence of Compressed Natural Gas (CNG), methane (CH4), and other gases in the air. Our MQ 4 sensor is used in the module. It simplifies the interface to the sensor's odd pin spacing by providing the interface via standard 4 x 0. 1?? header pins. It has an analogue output that corresponds to the concentration of gases in the air and a simple digital
