RANCANG BANGUN ALAT UKUR KALIBRATOR SUHU MENGGUNAKAN DS18S20 BERBASIS AVR ATMEGA 8535

Abstract

It has been conducted the planning and realization of making of appliance of calibrator of temperature with DS18S20 base on microcontroler AVR Atmega8535. This appliance serve the purpose of standarization of reference for measuring instrument or censors of analogous temperature other dissimilar, so that measuring instrument of the temperature have correctness of measurement which accurate, with output of display LCD. Design to develop, build this appliance is consisted of by censor of temperature of DS18S20 as detect asssess temperature measured, censor of temperature of LM35 as censor of comparator or tester censor, microkontroler AVR ATMega8535 to convert analogous data to digital and as value proccess, LCD as display of output data. This appliance work with measuring output of temperature from DS18S20. Later then the result compared to by censor of tester of LM35 having output in the form of tension of temperature too which before that,it must to converted from analogous data become digital by internal ADC in microcontroler ATMega8535. And measurement of temperature and also value proccess of this ADC will be presented in output of display LCD.
