MQ-7 Carbon Monoxide (CO) Gas Sensor Module

The MQ-7 Gas Sensor is designed for carbon monoxide (CO) detection, commonly used in air quality monitoring, safety alarms, and industrial applications. It operates using a metal oxide semiconductor (MOS) technology, where its resistance changes based on the presence of CO, providing an output signal proportional to the gas concentration.

🔹 Key Features

✔ Detects Carbon Monoxide (CO) with high sensitivity
✔ Dual Output – Analog (AO) & Digital (DO) signals for easy integration
✔ Adjustable Sensitivity – Potentiometer for threshold adjustment
✔ Fast Response & Recovery Time
✔ Low Power Consumption & Long Lifespan

📦 Package Includes

✅ 1 x MQ-7 Carbon Monoxide Gas Sensor Module

🚀 Applications

🔹 Carbon Monoxide Leak Detection
🔹 Air Quality Monitoring Systems
🔹 Industrial Safety Alarms
🔹 Smart Home & IoT Gas Detection
🔹 Fire & Gas Alarm Systems

📌 How It Works

1. Analog Output (AO): Provides a variable voltage based on CO concentration.
2. Digital Output (DO): Triggers HIGH/LOW signal when CO level exceeds the set threshold (adjustable via potentiometer).
3. Can be connected to microcontrollers like Arduino or Raspberry Pi to process data and trigger alarms.

🌟 Ideal for CO leak detection in homes, workplaces, and industrial settings to prevent carbon monoxide poisoning.
