MQ2 Gas Sensor Module – Smoke & Gas Detection for Arduino, ESP32, Raspberry Pi

Description

MQ2 Gas Sensor Module – LPG, Methane, Smoke & Combustible Gas Detector

The MQ2 Gas Sensor Module is a versatile and cost-effective sensor designed to detect a wide range of combustible gases and smoke. It is a popular choice among hobbyists, students, engineers, and developers who are building projects related to safety systems, home automation, and environmental monitoring.

With a fast response time and high sensitivity, this sensor is ideal for detecting gases such as LPG, methane, propane, hydrogen, alcohol, and smoke in the surrounding air. It’s fully compatible with development platforms like Arduino, ESP32, and Raspberry Pi, making it easy to integrate into your IoT or embedded project.

Built with a SnO₂ (tin dioxide) sensing layer, the MQ2 changes its resistance when exposed to certain gases, allowing accurate measurement of gas concentration. The module provides both analog and digital outputs, offering flexibility in how you collect and process data.

Whether you’re creating a smart gas detector, an industrial alarm, or a DIY gas-sensing project, this module delivers reliability and ease of use.
