sensore dht 11

-

ciao tutti, ho fatto un orologio da tavolo che mi segna anche la temperatura e l'umidità con il sensore in oggetto.
 la temperatura la segna abbastanza precisa ma ho un dubbio sull'umidità, perche ad ogni grado di temperatura che aumenta mi decrementa un grado di umidità, e in giornate calde e afose come questa mi sta segnando 30gradi e 19%di umidita e possibile secondo voi o ce qualcosa che non va?
grazie mille in anticipo

in questi giorni siamo tra il 50 e il 60% di umidità
