CO2 Monitor - Arduino Project Hub

The CO2 concentration is calculated from the measured resistance and the temperature/relative humidity correction. It may be written as: CO2 = 410*ppm*(Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to - according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is ...

Measuring CO2 Concentration using Arduino and MQ-135 Sensor

This project looks into designing and testing a CO2 sensor using an Arduino UNO. An MQ-135 sensor is tested under different conditions in order to obtain detection limits and measure trends. The literature shows that there is around 400 PPM of carbon dioxide in the atmosphere, the average indoor values range from 35-450 PPM and the maximum acceptable level is around 1000 PPM. The MQ-135 ...
