Desain dan Realisasi Sistem Kontrol Kecepatan dan Ketinggian Motor Menggunakan Sensor Optocoupler dan Sensor Ultrasonik Berbasis Arduino untuk Aplikasi Pengaduk Otomatis

Abstract

In this research, the design and realization of a control system for the height and speed of the motor has been designed and implemented. The system was made to adjust the mixer automatically based on Arduino. The working principle of this system was followed, firstly, the system is given an input of height in cm and the rotational speed in the form of rpm using a 4 × 4 keypad. Arduino used to adjust the ultrasonic sensor as an altitude reader and an optocoupler as a mixer rotary speed reader. The results of the calibration of the two sensors obtained data with a correlation coefficient are 0.991 and 0.970. The stability of the height system and the stirrer speed have good precision indicated by the coefficient of variations were 0.941% and 0.155%. The smaller the coefficient of variation, it is means the better the stability level of the tool. The system accuracy values for measuring the height and speed of the stirrer were 94.78% and 96.34%. So that the reading error of the two sensors are 5.22% and 3.66%. Thus the height control of system and the stirrer rotational speed have a fairly good quality.
