CO2 sensors

What is a carbon dioxide sensor?


A carbon dioxide (CO₂) sensor is a device that measures the concentration of carbon dioxide in a medium, such as air or a gas mixture. CO₂ sensors most commonly use infrared (IR) technology to measure carbon dioxide concentration. They are used in a variety of air quality monitoring, safety and process control applications. O₂ sensors are used in heating, ventilation and air conditioning (HVAC) systems to ensure that carbon dioxide levels in enclosed spaces are within safe limits.
In the food industry, CO₂ sensors are used to monitor fermentation processes where carbon dioxide is released.
In greenhouses, CO₂ sensors are used to monitor and regulate carbon dioxide levels, which can aid photosynthesis and plant growth.
