Membuat Alat Deteksi Kebakaran Menggunakan ARDUINO dan sensor Suhu DS18b20 serta Flame sensor (sensor api) dengan notifikasi sms SIM900A SMS GATEWAY

         Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat deteksi kebakaran dengan menggunakan sensor suhu ds18b20 dan sensor api, kemudian jika terjadi kebakaran atau sensor aktif maka akan mengirimkan notifikasi sms ke user. alat ini menggunakan Arduino sebagai processornya. berikut adalah komponen dan programnya.

a. Arduino Uno

b. Sensor Suhu DS18b20

 

c. Sensor Api

d. Modul SIM900A

 

e. Program Arduino IDE
