I was using the COZIR W-100 carbon dioxide sensor with an Arduino Mega 2560 with the example code from this site.

But the measured value of carbon dioxide by sensor was 90 ppm in fresh air and that is not correct. Please help me find the cause and a solution.

  • You're right. 90ppm is too low. Commented Jul 5, 2016 at 7:09
  • Since that is a 20% CO2 sensor, should you multiply by 5? Commented Jan 31, 2019 at 4:46
