MQ-7 Carbon Monoxide (CO) Gas Sensor Module

MQ-7 Carbon Monoxide (CO) Gas Sensor Module

Protect against the silent danger of Carbon Monoxide with the specialized MQ-7 CO Gas Sensor Module. This sensor is engineered for high sensitivity and reliable detection of Carbon Monoxide (CO), a colorless and odorless toxic gas produced by incomplete combustion. It is an essential component for building life-saving safety devices.

The MQ-7 is ideal for creating CO alarms for homes, garages, workshops, and vehicles. This easy-to-use breakout board includes all the necessary electronics, featuring a versatile dual-output system. The **Analog Output (A0)** provides a real-time voltage reading proportional to the CO concentration, while the **Digital Output (D0)** acts as a simple alarm, triggering when the concentration surpasses a user-defined threshold.

This trigger point can be precisely calibrated using the onboard potentiometer, allowing you to customize the sensor’s sensitivity for your specific safety application. For any project requiring dependable CO detection, the MQ-7 is a critical choice.

Key Features:

• Sensor Model: MQ-7
• Primary Detection: High sensitivity to Carbon Monoxide (CO)
• Dual Output: Provides both Analog (voltage) and Digital (HIGH/LOW) signals
• Adjustable Sensitivity: Onboard potentiometer to configure the digital alarm threshold
• Operating Voltage: 5V DC
• Interface: 4-pin header (VCC, GND, D0, A0) for simple connection
• Long Life and Stability: Designed for reliable, long-term operation

Applications:

The MQ-7 sensor is perfectly suited for a range of critical safety applications, including domestic carbon monoxide alarms, air quality monitoring in enclosed spaces, automotive exhaust gas detection, and industrial safety systems.
