Description
This data logger enables precise monitoring of CO2 air quality in indoor environments such as offices, classrooms, or apartments. It features a generous data storage capacity that can hold up to 50,000 measurements, allowing for comprehensive long-term recording of carbon dioxide concentrations, air temperature, and humidity values. The measurement intervals are freely selectable and range from one second to twelve hours. An integrated CO2 traffic light visualizes changes in air quality at a glance.
The recorded data can be conveniently transferred to a PC via a fast USB connection and analyzed and logged using the included analysis software. Thanks to the integrated Li-Ion battery, the CO2 data logger is suitable not only for stationary use on a table but also for mobile applications.
Furthermore, the data logger offers property management companies and landlords the opportunity to optimally monitor and, if necessary, adjust ventilation behavior by simultaneously recording humidity, temperature, and CO2 concentrations.
Automatic Calibration (Automatic Baseline Calibration)
The currently expected CO2 fresh air value is around 400 ppm (0.04 %vol). This is assumed by the device as the lowest threshold (baseline). A special algorithm now continuously monitors the lowest measured CO2 value from the sensor over several days. This occurs over a preconfigured time interval and slowly corrects any detected long-term drift compared to the expected fresh air value of 400 ppm (or 0.04%vol) CO2.
In normal indoor applications, the carbon dioxide level eventually drops to nearly outdoor air levels over the course of a week. By recording the values over a period of 8 days and subsequently comparing the lowest value with the 400-ppm point, the measuring device determines whether it needs to adjust the zero point or not. This happens completely automatically. The algorithm thus takes advantage of the fact that the CO2 level in buildings/rooms regularly stabilizes at a minimum for a certain period when they are unoccupied. In rooms that are permanently occupied or where there is a constantly elevated CO2 concentration (e.g., greenhouses), this principle of automatic calibration does not work.
