RANCANG BANGUN ALAT UKUR SUHU SKALA CELCIUS, REAUMUR, FAHRENHEIT DAN KELVIN DALAM PEMBELAJARAN FISIKA

Abstract

Development of science and technology, digital measuring instruments have been widely realized using the DS18B20 temperature sensor. However, there is no temperature measuring instrument in Celsius, Reaumur, Fahrenheit, and Kelvin scales which is practically visible on the LCD. This development research aims to design a digital temperature tool using the DS18B20 temperature sensor. The feasibility of the measuring instrument for learning physics is measured using sensor accuracy, namely the error value and the accuracy value of the measuring instrument against the comparison of thermometer and theory. The results of this study indicate that all of these tools can work well and help in the learning process. This tool may display the output of temperature in Celsius, Reaumur, Fahrenheit, and Kelvin scales instantly on the LCD. However, this research still has drawbacks. But to measure most hot temperatures above 85°C, this tool can't work because it produces error data.
