Carbon dioxide sensors are measuring devices used to monitor the concentration of carbon dioxide (CO2) in the air. They are used in a variety of applications including monitoring air quality in buildings, monitoring CO2 concentrations in industry and monitoring CO2 concentrations in the environment.
There are different types of carbon dioxide sensors based on different measurement principles, e.g. NDIR sensors, electrochemical sensors and optical sensors. Some of the most common types of carbon dioxide sensors are described below:
NDIR sensors: An NDIR (Non-Dispersive Infrared) sensor sends infrared light through the air sample and measures how much light is absorbed by the CO2 molecules. The amount of light absorbed is proportional to the concentration of CO2 in the air.
Electrochemical sensors: An electrochemical CO2 sensor consists of an electrode that reacts electrochemically with CO2. The change in electrical potential is measured and converted to CO2 concentration.
Optical sensors: An optical CO2 sensor uses the principle of light absorption by CO2. The sensor sends light through the air sample and measures how much light is absorbed. The amount of light absorbed is proportional to the concentration of CO2 in the air.
The accuracy and sensitivity of carbon dioxide sensors depend on several factors, such as the type of measurement principle used, the sensitivity of the signal processing and the accuracy of the calibration.
Choosing the right carbon dioxide sensor depends on the type of application, such as monitoring air quality in buildings or monitoring CO2 concentrations in industry, as well as the specific measurement requirements, such as accuracy, sensitivity, measuring range and operating temperature.

What are carbon dioxide sensors and how do they work?
Carbon dioxide sensors are devices that have been developed to measure the concentration of carbon dioxide (CO2) in the air. They are often used indoors to monitor air quality, especially in areas where many people are present, such as offices, schools, hospitals and public facilities.
Most carbon dioxide sensors use a measurement method called infrared absorption. An infrared beam is sent through a sample chamber or a detector. Carbon dioxide molecules absorb certain wavelengths of infrared light and the intensity of the transmitted light is measured. The higher the CO2 concentration in the air, the less light is transmitted. This measuring principle enables the sensors to take accurate CO2 measurements.
Modern carbon dioxide sensors are usually digital and provide continuous measured values. They can also be combined with other sensors to provide additional information on air quality, such as temperature and humidity. The measurement results can then be displayed in real time or transmitted to a monitoring system or building automation solution via a wireless connection.
The information provided by carbon dioxide sensors can help to optimize ventilation and the indoor climate in order to improve people's well-being and increase energy efficiency. A high CO2 concentration in the air can lead to tiredness, headaches and reduced concentration, while good ventilation and an appropriate CO2 concentration can make the indoor climate more pleasant.

How accurately do carbon dioxide sensors measure the CO2 content in the air?
Carbon dioxide sensors measure the CO2 content in the air using infrared radiation. They contain an infrared light source and a receiver that detects the reflected light.
When infrared light hits a surface, some of the light is absorbed, depending on the chemical attributes of the surface. CO2 absorbs infrared light at certain wavelengths, which makes it possible to determine the CO2 content in the air.
The sensor emits infrared light and measures the intensity of the reflected light. The higher the CO2 content in the air, the more light is absorbed and the intensity of the reflected light decreases. This measurement can be used to calculate and display the CO2 content.
Modern carbon dioxide sensors often use non-dispersive infrared (NDIR) technology, which is more accurate and stable. NDIR sensors consist of a light source, an interferometer and a detector. The interferometer separates the light into specific wavelength ranges and the detector measures the intensity of the light in each range. The CO2 content can be calculated by comparing the measured values with a calibration value.
