Thanks for your answer.

Cześć,

Od czasu do czasu czujnika DTH22 wykazuje zerową wilgotności i temperatury zera . Wszelkie ideea dlaczego? Mam conected do "LAN Controler " deska do przekaźnika , który jest o grzałkę oraz dwa wentylatory . Muszę ponownie uruchomić płytę , aby rozwiązać problem .

Dzięki za odpowiedź.

Any ideea?

you must restrt board to fix problem? Or value 0 are only by moment?

First you should try disconnect power to DHT. If this fix your problem buy new one sensor

Thank for your answer. I have to unplug the power for the board. Restarting from the webpage is not fixing the problem. I have seen that the problem is starting when an relay is going on ON. I have an relay board with four power relay. I will try to buy a new sensor. I even try to add an capacitor between vcc and gnd but is not fixing the problem
