Membuat Alat Monitor Water Flow Meter / Flow rate dan Water Level / Jarak HC-srf04 Bascom AVR interface Delphi 7

Membuat Alat Monitor Water Flow Meter / Flow rate dan Water Level / Jarak HC-srf04 Bascom AVR interface Delphi 7

              Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat digunakan untuk mengukur ketinggian air dan juga mengukur kecepatan aliran air menggunakan mikrokontroller, alat ini dapat menampilkan data di LCD dan interface grafik pada laptop / komputer dengan software DELPHI 7. untuk lebih jelasnya berikut adalah skema dan programnya.

a. Minimum System ATmega16

b. Sensor Jarak HC-SFR04

c. Sensor Water Flow / Flow Rate

d. PL232 Modul

e. Program Bascom AVR
