MQ136 Hydrogen Sulfide Gas Sensor H2S Detection Module

☠️ MQ136 Hydrogen Sulfide (H₂S) Gas Sensor Module – Industrial-Grade Toxic Gas Detection

The MQ136 Gas Sensor Module is specially designed to detect Hydrogen Sulfide (H₂S) — a toxic and flammable gas commonly found in industrial environments, sewage plants, and chemical labs. It’s ideal for gas leakage detection, air quality monitoring, and environmental safety projects. 🏭🧪

🔧 Key Features

🧠 Sensor Type: MQ136
☠️ Target Gas: Hydrogen Sulfide (H₂S)
📟 Output Type: Analog (A0) + Digital (D0)
⚡ Operating Voltage: 5V DC
📏 Detection Range: 1 – 100 ppm (varies by environment)
💡 Onboard Power & Signal Indicator LEDs
🔧 Adjustable Sensitivity via potentiometer
🔌 Interface: 4 Pins – VCC, GND, A0, D0

🧰 Package Includes

✅ 1x MQ136 H₂S Gas Sensor Module
📄 Pins: VCC, GND, A0 (analog), D0 (digital threshold output)
🧰 Compatible with Arduino, ESP32, ESP8266, Raspberry Pi, STM32, etc.

🧠 Perfect For

🏭 Industrial H₂S gas leakage detection
⚠️ Toxic environment monitoring
🌿 Smart air quality systems
📊 Environmental data logging
🎓 STEM & research-based gas sensor projects

🛠️ How It Works

1️⃣ Sensor reacts to the presence of H₂S gas
2️⃣ Analog Output (A0) gives real-time gas concentration
3️⃣ Digital Output (D0) goes HIGH/LOW based on set threshold
4️⃣ Can be used to trigger buzzers, relays, displays, or data loggers

🧠 Pro Tip: Pair with a relay module and alarm system for automatic H₂S leak alert in industrial areas or confined spaces! 🚨
