Implementasi Kontrol Lup Tertutup Multi Point Pada Pengatur Temperatur Oven Panggangan Roti

Abstract

A designed temperature control system is a multi-channel closed lup control system. This design controls 2 objects at once, namely 2 separate toaster plants with different temperature sets. The output system controls 2 heaters on-off. Feedback comes from each LM35 temperature sensor that reads the temperature of each oven. Setpoin is given through input i.e. potentiometer with the value of each setpoin so that it allows to differ from each other. To program the work of the system used the C programming language with AVR code as a compiler. The circuit is equipped with an LCD display so that it can facilitate the setting setting.  As a result, the system has been successfully assembled and tested with satisfactory results although there are still many shortcomings and weaknesses. The test results provide data on the performance of the tool to the time response and temperature stability.
