MQ-5 MQ5 Gas Detection Module MQ-5 LPG Natural Gas Coal Gas MQ5 Smoke Liquefied Flammable Methane Gas Sensor Module For Industrial And Engineering Electronics Project DIY

This MQ-5 gas detector is used for leak detection of LPG (Liquified Petroleum Gas), methane, propane, butane, natural gas and city gas, with low sensitivity to alcohol and smoke. Suitable for home and industrial use, it has fast response and recovery characteristics, long life and reliable stability.

The module features dual signal outputs: An analog output (0V to ~5V), the higher the gas concentration, the higher the voltage, and a digital TTL level output to signal the presence or absence of gas. The TTL threshold is adjustable with the onboard potentiometer.
