Datových listů je k dispozici víc variant. V některých je přesnost 2%, jinde 5%. Podle mého srovnání s kalibrovaným měřidlem bych řekl spíš 6%. Pro přesnější měření jsou k dispozici jiná, dražší čidla. Jinak, za ty peníze do amatérské meteostanice je to jednoduché a dobré čidlo.

Zajimalo by mě jak je to s přesností těchto čidel. Mám 7 kusů a na teplotě je rozdíl až 2 stupně a na vlhkosti rozdíl až 20.

Dobrý den, jak je uvedeno v datasheetu https://www.laskakit.cz/user/related_files/am2302_datasheet.pdf, tak přesnost měření teploty je ±1℃ max., typicky 0,5±℃. Přesnost měření vlhkosti je typicky ±2%RH.
