Detection of CO2 levels in the atmosphere is done using electrochemical carbon dioxide sensors. Polymer surfaces react with CO2 to produce an electrical charge when the gas enters the sensor. The concentration of CO2 can then be calculated based on the type and amount of electrical charge present in the atmosphere.
Is a CO2 sensor important?
Indoor carbon dioxide levels are critical to everyone’s health, safety, and building energy efficiency. To breathe fresh air, as we do, buildings need the same thing.
Where are CO2 sensors used?
A carbon dioxide sensor can be used to detect and measure the presence of carbon dioxide. CO2 detectors can be used to monitor indoor air quality, landfills, process control, and horticulture in controlled environments.
What causes high CO2 levels in house?
In a room or building with high CO2 levels, there is a risk of a lack of fresh air circulation and air movement. High CO2 levels indicate that the HVAC system should be inspected. Poor air quality and the extinguishing of gas-powered appliance pilot lights can result from high carbon dioxide levels.
Where is a CO2 sensor located?
Detectors should be mounted on a wall about five feet above the floor because carbon monoxide is slightly lighter than air and can be found with warm, rising air. On the ceiling, the detector can be installed. The detector should not be placed near or over a fireplace or other appliance that produces flames.
How long do CO2 sensors last?
The typical lifespan of a CO (carbon monoxide) detector is between 5 and 7. A “fuel-cell electro-chemical” sensor type and a “peak” level memory will be installed in their place.
How many CO2 sensors do I need?
Installing how many CO2 sensors? The rooms you want to control must have sensors installed. As many as fifty square meters per sensor.
