Accurate self-calibrating CO2 meter - forum.arduino.cc

Jun 28, 2021 · As a project at the University college of Odisee Energietechnologie (Belgium) we made 8 CO2 meters that indicate the quality of air and measure CO2. The meter uses an IR-sensor, UNO, LCD and battery pack and auto-calibrates itself (each 24 hours or shorter). With the link you'll find the code and a description of the hardware. We made a short documentation so that you have an idea about CO2 ...

Data logger for multiple carbon dioxide (SCD30) and …

20-07-2019 · In this project, we recorded CO2 and O2 data from six Sensirion SCD30 and Grove-ME2-O2 sensors using Arduino MEGA. While the ME2-O2 produce analog output, the SCD30 communicate via the I2C interface. Each SCD30 sensor has the same permanent I2C address, therefore, we use TCA9548A I2C multiplexer to read multiple SCD30.
