MQ-7 CO Carbon Monoxide Coal Gas Sensor Module Standard Quality

MQ-7 CO Carbon Monoxide Coal Gas Sensor Module detects the concentrations of CO in the air and outputs its reading as an analog voltage. The sensor can measure concentrations of 10 to 10,000 ppm.

The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.

This module provides both digital and analog outputs. The threshold level for digital output can be easily adjusted using the preset on the board. The MQ-7 sensor module can be easily interfaced with Microcontrollers, Arduino and etc.

Here are some common uses of the MQ-7 CO sensor module:

1. Home Safety: It’s used in home CO detectors to alert occupants of dangerous levels of carbon monoxide, helping prevent carbon monoxide poisoning.
2. Industrial Applications: Used in factories and industrial settings to monitor CO levels in areas where combustion processes occur, such as furnaces, boilers, and manufacturing plants.
3. Automotive Systems: Integrated into vehicles to monitor CO levels in the cabin and exhaust systems, ensuring compliance with emissions regulations and providing early warning of exhaust leaks.
4. Environmental Monitoring: Deployed in environmental monitoring systems to track CO levels in urban areas, near highways, and in industrial zones to assess air quality and potential health risks.
5. Firefighting and Rescue Operations: Utilized by firefighters and rescue teams to detect CO buildup in fire-affected areas or confined spaces, aiding in search and rescue efforts and ensuring the safety of responders.
6. HVAC Systems: Incorporated into heating, ventilation, and air conditioning (HVAC) systems to monitor indoor air quality and enable ventilation adjustments to maintain safe CO levels.
7. Research and Development: Used in scientific research and development projects to study combustion processes, indoor air pollution, and the effects of carbon monoxide on human health and the environment.
8. Gas Leak Detection: Employed in gas leak detection systems to identify leaks in pipelines, storage tanks, and industrial equipment, helping to prevent accidents and minimize environmental impact.
9. Occupational Safety: Deployed in workplaces where CO exposure is a concern, such as mines, chemical plants, and confined spaces, to protect workers from the harmful effects of carbon monoxide poisoning.
10. Consumer Electronics: Integrated into portable devices, such as handheld CO detectors and wearable monitors, to provide individuals with personal CO exposure monitoring and safety alerts in various environments.
