CO2 Monitoring As an AntiCovid19 Measure : 6 Steps (with ...

The CO2 sensor chosen here is an infrared NDIR CO2 sensor made by Gravity. Several other models exist on the market, although most are more expensive than this one. This particular model provides an analog output with a tension varying from 0 to 2V. This output is connected to pin A2 on the board. That pin is used as an analog input, and an instruction in the code activates its 12bit ADC ...
