MQ-2 Gas Sensor

🛑 MQ-2 Gas Sensor Module – Smoke, LPG, Methane & CO Leak Detection
The MQ-2 Gas Sensor Module is a high-sensitivity, low-cost sensor designed to detect a wide range of combustible gases like LPG, Methane (CH₄), Smoke, Butane, Propane, Hydrogen, and Carbon Monoxide (CO). Perfect for gas leak alarms, smoke detectors, and IoT safety systems. 🌫️🔥

🔧 Key Features
🧪 Sensor Type: MQ-2 (Metal Oxide Semiconductor)
📡 Detectable Gases: Smoke, LPG, CH₄, CO, Alcohol, Hydrogen
📈 Fast Response & High Sensitivity
⚙️ Adjustable Sensitivity via onboard potentiometer
📟 Outputs: Analog (A0) + Digital (D0)
⚡ Operating Voltage: 5V DC
🌡️ Preheat Time: ~20 seconds for stable output

🧰 Package Includes
✅ 1x MQ-2 Gas Sensor Module
📄 Pinout: VCC, GND, A0, D0
🧰 Compatible with: Arduino, ESP32, ESP8266, Raspberry Pi, STM32, etc.

🧠 Perfect For
🏠 Home gas leakage alarms
🚨 Smoke and fire detection
📦 Smart IoT safety monitoring
🏭 Industrial gas detection systems
🛠️ DIY air quality projects

🛠️ How It Works
1️⃣ Sensor detects gas concentration in the air
2️⃣ A0: Analog output (proportional to gas level)
3️⃣ D0: Digital output (based on set threshold)
4️⃣ Microcontroller can trigger alarms or automation on gas detection

🧠 Pro Tip: Pair it with a buzzer, relay, or GSM module for real-time alerts during gas leaks.
