MQ-2 Gas Sensor Module

The MQ-2 Gas Sensor Module is a versatile and highly sensitive gas detector designed to measure smoke, propane, methane, hydrogen, and alcohol levels in the air. Perfect for safety systems, air quality monitors, and Arduino-based IoT projects, this module provides both analog and digital outputs for flexible integration.

Key Features:

• Detects: Smoke, Liquefied Petroleum Gas (LPG), Methane, Hydrogen, and Alcohol vapors

• Operating Voltage: 5V DC

• Output Signals: Analog (AO) and Digital (DO) outputs

• Adjustable Sensitivity: Built-in potentiometer for fine-tuning detection threshold

• Fast Response Time: Quick detection with stable output

• Applications: Gas leak alarms, breath analyzers, air quality monitors, and smart home safety devices

Easy to use with microcontrollers like Arduino, ESP32, and Raspberry Pi, making it ideal for beginner to advanced electronic projects.
