CO (Carbon Monoxide) Gas Sensor Overview:
The CO Gas Sensor is used in gas detection equipment for detecting Carbon Monoxide in home, automotive or industrial settings. When paired with our Gas Sensor Board (#27983) it provides a development system and test platform for CO gas sensor design.
Key Features:
- Manufacturer Model MQ-7
- High sensitivity to Carbon Monoxide (CO)
- Stable and long life
- Simple drive circuit
Application Ideas:
- Safety Devices (harmful gas detection)
- Environmental monitoring
Note: Please refer to the manufacturer datasheet for more informaton and circuit recommendations.
Note: This sensor, when paired with our Gas Sensor Board (#27983), replaces our CO Gas Sensor Module (#27931). Please note that on boards labeled 27983 pin 2 is active-high, and on boards labeled 27904, 27930, 27931, and 27932, pin 2 is active-low.
