MQ-2 Gas Sensor Module | Smoke, LPG, Methane Detector for Arduino

Reliable MQ-2 Gas Sensor Module for DIY Electronics The MQ-2 Gas Sensor Module is a highly sensitive and reliable sensor designed for detecting combustible gases, including smoke, LPG, butane, methane, propane, and hydrogen. Whether you’re a hobbyist, student, or engineer, this module is perfect for DIY electronics and Arduino projects. Features: Wide Gas Detection Range – Detects smoke, LPG, methane, propane, hydrogen, and more. High Sensitivity – Reacts quickly to gas leaks, ensuring safety. Dual Output Options – Supports TTL digital output (DO) and analog output (AO). User-Friendly Design – Compatible with Arduino and other microcontrollers. Power Indicator LED – Shows working status. Stable and Durable – Long lifespan with reliable stability. Quick Response Time – Provides accurate results within seconds. Compact Size – Easy to integrate into DIY tech projects. Specifications: Input Voltage: 5V DC Current Consumption: 150mA Digital Output (DO): TTL logic 0 and 1 (0.1V to 5V) Analog Output (AO): 0.1V – 0.3V (clean air); Up to 4V (high concentration) Response Time: Fast response and recovery Mounting: 4 screw holes for easy positioning How It Works: The MQ-2 sensor operates by detecting changes in conductivity when exposed to combustible gases. As gas concentration increases, the sensor’s conductivity rises, generating a corresponding output signal. This makes it a cost-effective solution for gas leak detection in homes, factories, and research projects. Applications: Gas Leak Detection – Monitor LPG, propane, methane leaks at home or in industrial settings. DIY Smart Home Projects – Build an intelligent gas monitoring system. Air Quality Monitoring – Integrate into environmental safety devices. School & Engineering Projects – Great for hands-on learning and experiments. Package Includes: ✔ 1x MQ-2 Gas Sensor Module (100% Brand New) How to Use: Power Up – Connect VCC (5V) and GND. Signal Output – Use DO (digital output) or AO (analog output) as needed. Calibration – Allow a 20-second warm-up time for stable readings. Integration – Connect to Arduino, Raspberry Pi, or microcontrollers for real-time monitoring. Note: The sensor heats up during operation due to its internal heating element. This is normal and ensures accurate detection.
