11. Arduino-Projekt: CO2-Messung mit dem Sensor ... - blikk

· Der CO2-Gehalt der Luft wird in PPMs (Parts per Million) angegeben. 1 ppm entspricht bei Gasen 1 µL pro Liter Gas. Normale Luft hat etwa 400 ppm CO2-Gehalt, das entspricht 0,04% CO2-Anteil. Der Sensor funktioniert mit Spannungen bis 5,5 V und besitzt 5V-kompatible Signalein- und -ausgänge, was wichtig für den Betrieb am Arduino ist.

CO2 Sensor SEN0159 -

Ich habe einen CO2 Sensor an den Arduino angeschlossen. Eigentlich möchte ich die ppm des CO2s messen. Dazu verwendete ich den Beispielcode für den Sensor, doch die Ausgabe liefert mir negative Zahlen. Und das kann nicht sein. Was muss ich denn genau tun, um die werte von analogRead (die sind ja nur zwischen 0 und 1023) in die ppm Zahl umzurechnen? Der Beispielcode: Code: /*****Demo for …

Kohlendioxid CO2 Sensor (Arduino compatible) [SEN0159 ...

For that reason, this CO2 sensor is designed by DFRobot engineer. This is the first CO2 sensor in Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released. It ...

Indoor CO2 Sensor "kukO2" - Arduino Project Hub

The purpose of the "kukO2“ is to detect the CO2 content in indoor areas. It shows when the concentration or cognitive abilities decrese. Often many people stay a long time in one room and do not realize, how their concentration reduces. The shortage of O2 and with that the rising quantity of CO2 can be a cause.
