atmospheric carbon dioxide sensing with an Arduino ...

18/06/2018· I used an Arduino Nano to read the values from the sensor and send them to the laptop over the USB connection that was also powering it. The sensor can be calibrated in atmospheric CO2 conditions at the push of a button. I have reservations about this onepoint calibration but “you pays yer money…”, as my dad used to say. The Nano is sitting on a screw terminal shield with mount holes ...
