Decent inexpensive CO2 sensor Sensors Arduino Forum
6/5/2021· The MQ135 is just about as sensitive to several other gases as it is to CO2 (in fact it is MORE sensitive to CO), and the response depends strongly on temperature and humidity. Unless you use it under carefully controlled circumstances, it is impossible to know what you are actually measuring.
CO2 Sensor (Arduino Compatible) : : Industrial ...
Factory uncalibrated and frustratingly floats through baseline calibration algorithms that work for other co2/gas sensors. My NDIR sensors are far more reliable, calibrate on algorithm properly and only cost about 10 dollars more...look around and you''ll find them.
