MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor ModuleMQ4 High Sensitivity Gas Methane (CNG) Detector Sensor Module is a simple to use MQ 4 High Sensitivity Gas Methane (CNG) Detector Sensor Module which can sense the presence of Compressed Natural Gas(CNG), methane(CH4), etc in the air. The module uses our MQ 4 sensor. It simplifies the interface to the odd pin spacing of the sensor and provides the interface through standard 4 x 0. 1 header pins. It provides an analog output corresponding to the
