Zahořuji MQ135 už dva dny a stále mám chybné hodnoty. Zatím jsem na hodnotě což je čirý nesmysl když na světě je cca 380ppm CO2. Z Číny mi jde druhý modul abych zjistil zda ten co mám není náhodou KO. Obávám se zda to nebude problém ve slabém zdroji kterým napájím Adruino UNO. Mám na něm dataloger shield. Kdo ví jestli to utáhne ten modul.
