Monitoring Input Relay LDR dan SMS Gateway + RTC

 Monitoring Input Relay LDR dan SMS Gateway + RTC

          Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang menggunakan relay sebagai input untuk mengaktifkan sms, jadi jika sensor ldr terkena suatu kondisi tertentu maka akan melakukan sms ke nomer yang dituju. untuk lebih jelasnya berikut adalah program dan komponenya. 

 

 

 

a. Minimum System ATMega328 / Arduino Uno

b. Modul SIM900A

c. Relay Input LDR

d. Program Arduino IDE
