Monitor Suhu Kelembaban ONLINE 2 Node ESP8266 Thingspeak Penampil DMD P10 Arduino
Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat memonitor 2 ruangan yang jaraknya berjauhan, parameter yang dimonitor adalah suhu dan kelembaban ruangan, tampilan angka berada di ruang kontrol yang jaraknya juga berjauhan dengan ruangan yang dimonitor untuk itu project ini menggunakan internet dan server Thingspeak untuk transfer datanya. untuk lebih jelasnya berikut adalah koding dan komponennya.
