🧪 MQ131 Ozone Gas Detection Sensor Module – Accurate O₃ Monitoring for Air Quality Projects

The MQ131 Gas Sensor Module is specially designed to detect ozone gas (O₃) in the air with high sensitivity. Ideal for air quality monitoring systems, environmental research, industrial safety, and smart IoT applications, this sensor ensures real-time O₃ level detection to help maintain clean and safe environments. 🌍🌫️

🔧 Key Features

🌬️ Target Gas: Ozone (O₃)
📏 Detection Range: 10 ppb – 2 ppm (depending on version)
⚙️ Output Type: Analog (A0) + Digital (D0)
⚡ Operating Voltage: 5V DC
🔧 Adjustable Sensitivity via onboard potentiometer
💡 LED Indicators for Power and Digital Signal
🔌 Pins: VCC, GND, A0, D0

🧰 Package Includes

✅ 1x MQ131 Ozone Gas Detection Sensor Module
📄 4-Pin interface: VCC, GND, A0, D0
🧰 Compatible with Arduino, ESP32, Raspberry Pi, STM32, and more

🧠 Perfect For

🏭 Ozone leak detection in industrial setups
🌿 Air purification system monitoring
📦 IoT-based air quality control
📊 Environmental science & research projects
🎓 Smart city or smart agriculture systems

🛠️ How It Works

1️⃣ Sensor detects O₃ levels in the surrounding air
2️⃣ A0 Pin: Analog voltage output (based on gas concentration)
3️⃣ D0 Pin: Digital HIGH/LOW signal (based on threshold setting)
4️⃣ Microcontroller reads output to log data, trigger alarms, or control devices

🧠 Pro Tip: Use with an OLED display, WiFi module, or buzzer for live monitoring or instant alerts! 📲🔔
