Salve a tutti, Sto simulando una camera di albergo con controllo accessi tramite lettore di card rfid, che fa accendere una luce quando la luminosità e bassa grazie alla fotoresistenza che ho integrato. Vado al dunque ho inserito un sensore dht 11, ho preso lo sketch dal kit 37 sensori elegoo; il mio problema è che non riesco a fare visualizzare la temperatura sul monitor seriale. Posto lo sketch, se c'è qualche anima pia che mi può aiutare grazie...
