Carbon dioxide sensors measure CO2 levels in gases and liquids, used in various industries and scientific fields. In air conditioners, they monitor air quality and adjust temperature accordingly. They are also used in medical procedures, identifying CO2 levels in blood, and in the production of carbonated beverages. The main type of sensor is NDIR, measuring absorption of light to determine CO2 content.
A carbon dioxide sensor is a device that measures the level of carbon dioxide in a gas or liquid. Carbon dioxide sensors are used in many scientific fields and industries to determine the carbon dioxide (CO2) content of an environment or product. Carbon dioxide sensors are also used to monitor indoor air quality.
In consumer use, carbon dioxide sensors are often used in air conditioners to measure air quality, as high levels of carbon dioxide can cause headaches and can even be fatal at extremely high levels. A sensor in an air conditioning (AC) unit can also determine how many people are in a room from the amount of carbon dioxide produced by the room’s inhabitants. With this information, an air conditioner can adjust the air conditioning to a comfortable temperature for that situation. A carbon dioxide sensor has similar uses for determining the number of animals in an environment or the respiratory conditions of those animals.
The ability to measure carbon dioxide in a gas is critical in several industries. Using a carbon dioxide sensor in a hyperbaric chamber allows doctors to perform operations under carefully controlled atmospheric conditions. A sensor is also used to determine carbon dioxide levels underwater or in space, which can be used to determine the habitability of a new environment.
A carbon dioxide sensor can also be used to identify the CO2 content in a liquid. These sensors are used to measure the levels of carbon dioxide in the blood. This is a crucial measurement during surgery and when a patient is admitted to intensive care.
A dissolved carbon dioxide sensor can be used in the production of several common items. The sensors are used to monitor CO2 in carbonated beverages, such as soda, beer and sparkling wine, which are carbonated by pressurized carbon dioxide. Dissolved carbon dioxide sensors are also used in the pharmaceutical industry, where CO2 has many uses.
The main type of carbon dioxide sensor is known as a non-dispersive infrared (NDIR) sensor. An NDIR determines the amount of carbon dioxide in a gas by measuring the absorption of a certain wavelength of light in the gas. Carbon dioxide has a unique absorbing quality and the amount of light absorbed by the gas will show how much carbon dioxide is in that gas. Other carbon dioxide sensors measure thermal conductivity, or the ability of a substance to conduct heat, to determine the CO2 content.
