CO2-Messgerät ganz einfach selber bauen

· CO2 und Corona . Das Coronavirus kann über Aerosole übertragen werden. Nach wie vor ist unklar, wie wichtig dieser Übertragungsweg ist. Dass das Ansteckungsrisiko in Innenräumen beträchtlich höher ist als im Freien, legt allerdings nahe, dass Aerosole eine bedeutende Rolle bei der Übertragung spielen. Es ist deshalb sinnvoll, durch Lüften die Konzentration von Aerosolen in …

CO2 Monitor - Arduino Project Hub

The CO2 concentration is calculated from the measured resistance and the temperature/relative humidity correction. It may be written as: CO2 = 410*ppm* (Rs/f_RH_T / Rs410/f_RH_T_410)^b Where the exponent b is equal to - according to Mad Frog.

Makerschule - CO2-Ampel

Zum Test haben wir mit Hilfe eines Arduinos eine Ampelschaltung programmiert (siehe Video). Parallel haben wir aus der Praxis ermittelt, dass Werte bis 1000 ppm CO2 für Unterrichtsräume in Ordnung (=Ampelfarbe grün) sind, bis 1400 ppm noch vertretbar (= gelb) sind und darüber ROT angezeigt werden muss. Wir wünschten, dass wir die Werte ...

Makerschule - CO2-Ampel

I tried a number of analog CO2 sensors for that project, but I ran into calibration issues - until I got a K30 CO2 module. This is a NDIR, digital, auto-calibrating sensor, so it's pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino.

CO2-Monitor - Arduino Project Hub

· This CO2 monitor gives you a survey over the CO2 contentration over one day. With its NIR CO2 sensor it is extremely sensitive to ventilation or just opening the door of the bedroom in the morning. For evaluation purpose the monitor can record the CO2 data for about 5 days and replay them to the COM-interface of the arduino nano.
