Product Description
This module is a MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor that can detect compressed natural gas (CNG), methane (CH4) and other gases in the air. It uses the MQ-4 sensor and has a standard 4 x 0.1″ header pin interface. The module has an analog output that varies with the gas concentration and a digital output that triggers when the gas concentration exceeds a threshold. The threshold can be adjusted with the onboard potentiometer. The module also has an LED indicator for gas detection. The module works with 5V power supply.
The digital output is easy to connect to microcontrollers and other circuits. The analog output can be connected to an ADC of a microcontroller to get a wide range of sensor readings. This module is suitable for sensing natural gas, which is mainly composed of methane (CH4), in the air.
The MQ-4 can sense natural gas concentrations from 200 to 10000ppm.
