Gas Sensor MQ-4 | SUNROBOTICS

Principle: The MQ4 gas sensor gives output voltage based on the concentration of Methane gas detected in the surrounding. It provides an analog output corresponding to the concentration of the gases in the air and an easy to use digital output. The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered.
