NDIR CO2 Sensor code queries Adafruit customer service ...

Jul 16, 2017· Re: NDIR CO2 Sensor code queries. by adafruit_support_mike on Sat Jul 15, 2017 1:01 am. 1) The output value is being calculated in millivolts, and there are 5000 millivolts in 5v. 2) 16/50 calculates voltage in terms of ppm: v=ppm*16/50. To calculate ppm in terms of voltage you have to invert the equation: ppm=v/ (16/50)=v*50/16.
