Berikut code program sensor Dht 12 realtime terhubung dengan aplikasi blynk dan terkoneksi Thingspeak terkoneksi dengan internet dapat menghubungkan dengan wifi hotspot yang ada dirumah anda
selain itu fungsi dari sensor dht tersebut dapat mengetahui suhu raungan dan temperature yang ada dirumah ....
dapat di copy code dibawah ini lalu paste ke arduino ide....
