Simple LED Bar Graph CO2 Sensor : 4 Steps (with Pictures ...

TOPTICA, the company I work at, even designed their own CO2 sensor shield for the Arduino UNO and the bare PCB was given away for free to everybody interested in building their own sensor. This inspired me to build my own variation of a CO2 sensor using the SCD30 sensor that I generously received for free from my employer. The SCD30 is relatively expansive compared to some other gas sensors ...
