A CO2 sensor is an electronic device that measures the concentration of carbon dioxide (CO2) in the air. It is commonly used in various applications, including indoor air quality monitoring, ventilation control, and industrial safety. In this article, we will explore what a CO2 sensor is, the problems it solves, applications that use it, technical data, and the main manufacturers.
What is a CO2 Sensor?
A CO2 sensor is an electronic device that measures the concentration of carbon dioxide (CO2) in the air. It typically uses infrared radiation to detect the presence of CO2 molecules in the air and provides an output signal that is proportional to the concentration of CO2.
Problems Solved by CO2 Sensors:
CO2 sensors solve a range of problems in various industries. In indoor air quality monitoring, CO2 sensors are used to ensure that the concentration of CO2 in the air does not exceed safe levels, which can lead to health problems such as headaches, dizziness, and fatigue. In ventilation control, CO2 sensors are used to adjust the flow of fresh air into a building based on the number of people present, ensuring that the indoor air quality remains within acceptable levels. In industrial safety, CO2 sensors are used to detect leaks of CO2, which can be harmful or even fatal to workers.
