Detail Description

MQ-5 Gas Sensor Module is a high-sensitivity combustible gas sensor capable of detecting a wide range of flammable gases including LPG, natural gas, coal gas, methane (CH₄), and hydrogen (H₂). The sensor operates by changing its internal resistance when exposed to target gases, which is converted into an electrical signal.

This module provides both analog output for measuring gas concentration levels and digital output for threshold-based gas detection. An onboard adjustable potentiometer allows users to set the sensitivity according to environmental conditions and safety requirements.

MQ-5 Sensor Module can be easily interfaced with Arduino, ESP8266, ESP32, and other microcontrollers. It is commonly used in gas leakage detection systems, home and industrial safety alarms, IoT safety devices, and electronics learning projects. Pre-heating is required for stable and accurate readings.
