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.

ARDUINO PROJECTS -

ARDUINO analog inputs have a very high impedance, so any stray voltage picked up can cause random readouts or 'beep-beep' when no RF-power is applied, in this case, put a 220k or 470k resistor from FWD and REFL inputs to ground. Off course all wiring to coupler must be shielded and properly RF-decoupled !

digitalRead() - Arduino Reference

06-07-2021· Notes and Warnings. If the pin isn’t connected to anything, digitalRead () can return either HIGH or LOW (and this can change randomly). The analog input pins can be used as digital pins, referred to as A0, A1, etc. The exception is the Arduino Nano, Pro Mini, and Mini’s A6 and A7 pins, which can only be used as analog inputs.
