2021-07-02· Über den Beitrag. Bei den CO2 Sensoren zur Überwachung der Raumluftqualität gibt es zwei vorherrschende Technologien. In meinem letzten Beitrag hatte ich über die relativ teuren, aber nach meiner Erfahrung auch zuverlässigen NDIR CO2 Sensoren berichtet. Hier möchte ich nun die günstigeren, Metalloxid-basierten TVOC und eCO2 Sensoren behandeln.

The iot CO2 and volatile organic compounds (VOC) sensor detects harmful indoor air quality conditions. The EPA states that indoor air quality is typically worse than outdoor and estimates that 50 to 300 different VOCs may be detected in the air of homes, schools, offices, and commercial buildings at any given time that can have adverse health effects caused by breathing in these chemicals.
A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air. Whereas outside air carbon dioxide levels tend to be relatively low and constant, an indoor CO2 measurement can be used to determine whether a room or building is occupied.
