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.

c Senzor CO2 MQ135 citiri impare

Am un senzor de gaz MQ135. Eu folosesc codul de exemplu din biblioteca am importat, dar lecturile pe care le primesc sunt în jur de 48 PPM, în cazul în care ar trebui să fie în jur de 400 PPM. Când am respira pe senzor, pot vedea o schimbare în valorile astfel încât senzorul nu citește ceva, Senzorul este conectat direct la A0, VIN, GND.
