Temp and Co2 - I vented my basement and the temp sensor responded accurately for the decrease in temp as well as the increase when I shut the windows. Same with Co2 levels and air pressure which was a little more challenging to test. Humidity was in the yellow on my Airwave Plus detector in my great room. I placed a humidifier nearby and this unit responded with accurate readings as promised ...

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 ...

CO2 Sensors vs. VOC Sensors for IAQ - What's the ...

A CO2 sensor is designed to control the ventilation rate in occupied spaces. People are the principal source of CO2 in indoor air. Whereas outside air carbon dioxide levels tend to be relatively low and constant, an indoor CO2 measurement can be used to determine whether a room or building is occupied. In other words, higher levels of CO2 correspond to larger numbers of people inside, and ...

Gravity: Analog CO2 Gas Sensor | Arduino Official Store

This is the first CO2 sensor compatible with Arduino. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (the voltage is lower than the threshold), a digital signal (ON/OFF) will be released. It has MG-811 sensor module which is highly sensitive ...
