Why is Carbon Dioxide (CO2) measured?
Unlike other air pollutants such as tobacco or formaldehyde, carbon dioxide (CO2) is impossible to detect with your senses alone. As mentioned, carbon dioxide (CO2) is colourless and odourless. It is not toxic, however, it is toxic at higher concentrations.
How is Carbon Dioxide (CO2) measured?
Carbon Dioxide (CO2) is measured with a gas sensor specifically made to measure the concentration of carbon dioxide (CO2) in the air. There are three main types of Carbon Dioxide (CO2) sensors: Electrochemical sensors, Non-Dispersive Infrared (NDIR) Sensors, and Metal Oxide Semiconductor (MOS) Sensors.
Current Real-World Applications
Modified Atmosphere Packaging is to control the atmosphere of the environment where foods are packaged to ensure the optimum freshness to maintain visual and nutritional appeal. Precise control of the package’s gaseous environment is required, so the shelf life of the product can be extended without adding preservatives.
Summary
It is not that difficult to measure carbon dioxide. There are three different kinds of sensors, but NDIR is the most widely-used one. I hope you have learnt plenty about carbon dioxide sensors in this article. Carbon dioxide measurements are required in many scenarios.
What is a carbon dioxide meter used for?
The carbon dioxide meter is used to measure and store environmental data such as temperature, humidity , illuminance, CO2 content and TVOC concentration. The carbon dioxide meter also calculates the dew point, absolute humidity and the water vapor content in the air.
Why do we need a carbon dioxide meter?
The carbon dioxide meter supports the function of data storage and further data transfer of measuring results to a computer. Therefore, it is possible to take long-term measurements in order to capture the carbon dioxide content of a specific place for a longer period. Also, you can find a carbon dioxide meter for fixed installations.
What is a CO2 meter?
The carbon dioxide meter measures the CO2 content in the air and shows the measured value on a large LCD display. The CO2 content in the air is an important measure for checking the ventilation behavior in offices, classrooms, lecture halls, etc.
What is a PCE AQD 10ICA?
The Carbon Dioxide Meter PCE-AQD 10-ICA is used to measure air quality. The carbon dioxide meter measures carbon dioxide, temperature and humidity. The CO2 sensor from the carbon dioxide meter is disconnected from the main unit with a connection cable.
What is the chemical formula for CO2?
The chemical formula CO 2, also written CO2 in simplified form, stands for carbon dioxide. Carbon dioxide is a natural component of the atmosphere but is also produced by human and animal metabolism, fermentation and combustion processes. Many soft drinks contain carbon dioxide dissolved in water only a small proportion of which reacts with the water to form carbonic acid. When the pressurised bottle is opened, bubbles rise and the carbon dioxide is released from the liquid into the ambient air. Besides water and sunlight, plants need the carbon dioxide for photosynthesis during which glucose is produced in the plant and oxygen is released into the environment.
What is a PCE-CMM 10?
The carbon dioxide meter PCE-CMM 10 is a multi-function meter for measuring the air quality. This carbon dioxide meter measures synchronously the CO2 concentration, the air temperature and the humidity.
How is carbon dioxide produced?
In normal common rooms, carbon dioxide is mainly produced by the respiration of the people present. The more people present in the room, the faster the carbon dioxide concentration increases. A simple carbon dioxide meter with a traffic light signal enables users to ventilate as required.

Nondispersive Infrared (NDIR) CO2 Sensors
NDIR sensors are spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption. The key components are an infrared source, a light tube, an interference (wavelength) filter, and an infrared detector. The gas is pumped or diffuses into the light tube, and the electronics measure the absorption of the characteristic wavelength of light. NDIR sensors are most oft…
Photoacoustic sensors
CO2 can be measured using photoacoustic spectroscopy. Concentration of CO2 can be measured by subjecting a sample to pulses of electromagnetic energy (such as from a Distributed Feedback Laser ) that is tuned specifically to the absorption wavelength of CO2. With each pulse of energy, the CO2 molecules within the sample will absorb and generate pressure waves via the photoacoustic effect. These pressure waves are then detected with an acoustic detector and co…
Chemical CO2 sensors
Chemical CO2 gas sensors with sensitive layers based on polymer- or heteropolysiloxane have the principal advantage of very low energy consumption, and that they can be reduced in size to fit into microelectronic-based systems. On the downside, short and long term drift effects, as well as a rather low overall lifetime, are major obstacles when compared with the NDIR measurement principle. Most CO2 sensors are fully calibrated prior to shipping from the factory. Over time, th…
Estimated CO2 sensor
For indoor environments such as offices or gyms where the principal source of CO2 is human respiration, rescaling some easier-to-measure quantities such as volatile organic compound (VOC) and hydrogen gas (H2) concentrations provides a good-enough estimator of the real CO2 concentration for ventilation and occupancy purposes. Sensors for these substances can be made using cheap (~$20) MEMS metal oxide semiconductor (MOS) technology. The reading the…
Applications
• Examples:
• For indoor human occupancy counting
• For HVAC applications, CO2 sensors can be used to monitor the quality of air and the tailored need for fresh air, respectively. Measuring CO2 levels indirectly determines how many people are in a room, and ventilation can be adjusted accordingly. See demand controlled ventilation (DCV).
