· In the DHT22 module, the green wire corresponds to the data pin and in the CO2 module the blue wire corresponds to the data pin. I’m not sure if different units may have different colors in the data pins, but the red and black wires should follow the convention of VCC and GND, respectively. Please analyse your devices carefully before proceeding with the connection. Note that the DHT22 …
· Das Modul hat einen CCS811 Sensor zur Messung von CO2 und TVOC und einen BME280 zur Messung von Temperatur, relativer Luftfeuchtigkeit und barometrischem Druck.

· KEYESTUDIO CCS811 Kohlendioxid-Luftqualitätssensor für Arduino für flüchtige organische Verbindungen (TVOCs), äquivalentes Kohlendioxid (eCO2) und Metalloxid (MOX)
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 has MG-811 sensor module onboard which is highly sensitive to CO2 ...

MG-811 CO2/Carbon Dioxide Sensor Module for Arduino. This sensor module has an MG-811 onboard as the sensor component. There is an onboard signal conditioning circuit for amplifying output signal and an onboard heating circuit for heating the sensor. The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO.
· I'm trying to measure CO2 concentrations with this sensor (link above). I have a 6V battery connected to a breadboard. I connected VDD pin of the module with the 5V pin on arduino, the GND to GND on arduino and the AOUT on A0 pin on arduino. Also, I connected the Vin pin of arduino to the 6V on breadboard with the respective grounds.
