Pada kesempatan yang berbahagia kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang digunakan untuk monitoring polusi udara menggunakan internet webserver. alat ini hanya digunakan untuk monitoring jarak jauh tanpa bisa kendali jarak jauh, jadi terdapat dua buah arduino yang mana arduino 1 untuk mengolah menjadi data ppm kemudian arduino 2 digunakan untuk mengirim data ke server, sebenarnya menggunakan 1 arduino saja bisa namun dikarenakan pinout-nya tidak cukup maka digunakanlah 2 arduino. sensor yang digunakan bisa dimodifikasi sesuai keinginan, untuk lebih jelasnya berikut skema dan programnya.
a. Arduino Uno + Ethernet Shield
b. Router + Modem GSM
c. Cara Konfigurasi Web Hosting
d. Program Arduino IDE
