Description

MQ-4 MQ4 Gas Sensor Module Methane Natural Coal Co Methane Detector Module Arduino

Description Gas sensor

MQ-4 methane CNG gas sensor module for measuring the concentration of methane / natural gases.
e.g. to detect gas leaks. (Gas alarm)
Is often operated with Arduino and Raspberry Pi boards.
The threshold from which the module responds can be set using a potentiometer.
Please note:
The module is heated up and operated warm. Exact measurement results are only delivered when they are warm.
