Carbon dioxide has a very negative effect on the human body and is a carcinogen. Being in a room with a high concentration of CO2 can cause weakness, drowsiness, headaches, and problems with concentration. In this regard, it is necessary to monitor the level of CO2 and take measures to reduce it.
To date, there are several options for available sensors for measuring CO2 levels: SenseAir S8, MH-Z19, AQC. All of them are supported by the software.
There are modifications with temperature sensor DS18B20
The CO2 sensor can be used to monitor and control HVAC, or just send alerts when the level of carbon dioxide is exceeded.
Specifications:
SenseAir S8 sensor:
CO2 measurement range: 400 to 2000ppm
Accuracy of CO2 readings: ± 30 ppm + 2% of reading
CO2 sensors MH-Z19 and AQC:
CO2 measurement range: 400 to 5000ppm
Accuracy of CO2 readings: ± 50 ppm + 5% of reading
Temperature sensor DS18B20:
Temperature measurement range: -55…+125°C
