Membuat Alat Monitoring Jarak Menggunakan HC-SRF04 dan OUTPUT SMS GATEWAY - ALARM INDIKATOR

Membuat Alat Monitoring Jarak Menggunakan HC-SRF04 dan OUTPUT SMS GATEWAY - ALARM INDIKATOR

       Pada tengah malam ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang fungsinya yaitu untuk memonitor jarak benda atau jarak air / ketinggian level air menggunakan sensor ultrasonik HC-SRF04 dengan output sms, alarm buzzer dan indikator led, selain itu ada sebuah motor yang digunakan untuk membuka palang pintu air saat air telah mencapai level tertentu, kemudian akan menutup kembali saat mencapai level yang telah di setting sebelumnya. untuk lebih jelasnya berikut adalah skema dan programnya.

a. Arduino Mega

b. Modul SMS SIM800L

c. Buck Converter Modul

d. Sensor HC-SRF04

e. Motor Driver L298

f. Program Arduino IDE

// hubungkan RX-TX di pin 50 dan 51
