About this product
The MQ-4 is a metal-oxide gas sensor module with high sensitivity to methane (CH4) and natural gas, and lower sensitivity to alcohol and smoke. It provides an analog output for measuring the gas level and a digital output that changes state when gas is detected. It is commonly used in gas leak detection projects with Arduino and similar boards.
