Error of Assembly Microcontroller Arduino Mega and ATmega in the Control of Temperature for Heating and Cooling System

Abstract

Microcontroller Arduino Mega and ATmega is a computer chip that needed and developed to control system or process. Microcontroller Arduino Mega and ATmega can be used to temperature control systems [1][2][3], the room lighting control, security control, the hazard warning [4], scheduling, monitoring water flow and dams actuator door and etc. Most studies on the microcontroller is focused on the functional capability of a microcontroller to read or measure the object. In addition to aspects of good function, microcontroller must have a high sensitivity in order to avoid delay or in-accuracies in the sensor reading measured object such as temperature. Microcontrollers has some advantages and disadvantages of the process accuracy depends on the processor and the ability microcontroller. In this paper focuses on the measurement errors that occur on microcontroller Arduino Mega and ATmega 8535 with a temperature sensor LM 35 and hygrometer digitizes dt05 for the application process cooling and heating sea water controls. The volume of sea water is measured is 3 to 35 litters with a temperature set point 28°C of lower temperatures above 25°C and 31°C. The results show that the maximum error obtained by using microcontroller Arduino Mega is 1,32°C or 13,2 mV and ATmega 8535 is 0,2°C or 2 mV. Also the microcontroller Arduino Mega is more suitable for control temperature measurement in the process of heating and cooling sea water.

Sistem Kontrol Kekeruhan Dan Temperatur Air Laut Menggunakan Microcontroller Arduino Mega

“…Pada penelitian terdahulu microcontroller digunakan untuk mengatur sirkulasi air panas dan dingin pada kolam ikan kerapu menggunakan ATmega dan Arduino Mega [1] [2]. Ikan kerapu [3] merupakan ikan yang sangat memiliki potensi ekspor yang tinggi dimana memerlukan pengontrolan pada kondisi habitat ikan tersebut jika dilakukan pembudidayaan seperti ikan kerapu tikus, ikan kerapu macan [4][5] dan ikan kerapu lumpur.…”

“…Hal ini dikenal dengan sistem kontrol biologis [7] yaitu menyeimbangkan kondisi mikrobiologis dengan menggunakan bakteri seperti Alteromonas sp., Bacillus sp., Lactobasillus sp., Thiobacillus sp., Photosyntetic bacteria, dan bakteri asam laktat (BAL). Selain kontrol biologis juga dapat dilakukan dengan kontrol mekanik dan elektrik yaitu kontrol otomatis menggunakan microcontroller [1][2][8].…”
