The MQ-7 is a high-quality carbon monoxide (CO) sensor designed for detecting CO gas in various environments. It features a double-sided board design that enhances stability and power efficiency, along with built-in indicators for easy status monitoring. The sensor offers both TTL and analog output signals, making it versatile for integration into a variety of systems. Its sensitivity to carbon monoxide is excellent, allowing it to quickly detect and respond to changes in CO concentration.

The TTL output is a low-level signal when active, which can be directly connected to microcontrollers, while the analog output increases as the CO concentration rises, providing precise measurements. The MQ7 sensor has a long lifespan, fast response time, and reliable stability, making it ideal for applications such as air quality monitoring, safety systems, and gas leak detection.

With four mounting holes, installation is made easy and secure, ensuring the sensor stays in place for consistent and accurate readings. Whether you’re building a gas detection system or need a reliable CO sensor for your project, the MQ7 offers an affordable and high-performance solution.

Feature:

• High Sensitivity: Provides accurate detection of carbon monoxide (CO) gas.
• Dual Output: TTL output (low level when active) and analog output (voltage increases with CO concentration).
• Easy Integration: Can be directly connected to microcontrollers for real-time monitoring.
• Reliable and Durable: Long service life with fast response and recovery.
• Mounting Holes: Four screw holes for easy and secure installation
