Product Description
Protect your environment with the MQ-2 Gas and Smoke Sensor Module, a versatile and high-sensitivity detector designed for both residential and industrial safety systems. The sensor utilizes a Tin Dioxide (SnO2) semiconductor layer that changes its conductivity based on the concentration of combustible gases and smoke in the air. This module is particularly effective at detecting LPG, Propane, and Butane, making it an essential component for gas leak alarms and fire detection projects. At Robogears, we provide this module with an integrated comparator circuit, offering both a precision analog output for concentration measurement and a digital trigger output with an adjustable threshold for easy integration with microcontrollers like Arduino, ESP8266, and Raspberry Pi.

Detailed Key Features
Wide Detection Spectrum: Capable of sensing a broad range of flammable gases including LPG, Propane, Hydrogen, and smoke, providing comprehensive environmental monitoring.
Dual Output Mode: Features an Analog output (A0) for real-time concentration tracking and a Digital output (D0) for simple "high/low" alert triggering.
Adjustable Sensitivity: Equipped with an onboard multi-turn potentiometer to calibrate the digital trigger point according to your specific environment.
Rapid Response & Recovery: Engineered to provide near-instant detection (under 10s) and quick recovery after the gas source is removed.
Long-Life Stability: Built with a robust SnO2 sensor element that offers high stability and a long operational life under standard conditions.
