Automatic LPG Gas Leakage Detector Using Arduino (Auto Shut-Off Valve Project)

Stop trusting a ₹20 rubber washer with your life. In this video, I build a Smart LPG Gas Leakage Detector using an Arduino Uno and an MQ2 sensor. This isn't just a beeping alarm—it physically turns off your gas regulator knob using a high-torque Metal Gear Servo (MG90S) the moment a leak is detected. 🔴 Get the Circuit Diagram, Code & Full Guide Here: https://learniot.in/lpg-gas-leakage-d... Why this project is different: Most tutorials just blink an LED. My system uses Safety Hysteresis Logic: Detects: Gas levels above 600 PPM. Acts: Servo instantly snaps the regulator knob to "OFF". Resets: The servo arm returns to the "Ready" position automatically, but—Crucial Safety Feature—the gas regulator stays OFF until you manually turn it back on. No automatic restarts! Hardware Used: Brain: Arduino Uno R3 Sensor: MQ-2 Gas/Smoke Sensor Muscle: MG90S Metal Gear Servo (Do NOT use plastic SG90!) Display: 16x2 LCD with I2C Module Power: 2x 470uF Capacitors (To prevent brownouts) Timestamps: 0:00 - Why manual checking is dangerous 0:28 - BOM with explanation 0:53 - Pin Diagram with clear explanation 1:03 - LIVE TEST: Watch the Auto-Cutoff in action!
