Construction of an Educational Device for Real Time Data Acquisition Based on Arduino for a Calorimetric Study

The general idea is to measure the heat increase of a liquid due to a quantity of electrical energy, by heating a mass of cold water with a heating resistor carrying an electric current. We used a platform based on Arduino and a DS18B20 temperature sensor to automatically collect temperature data, and the Data Streamer add-in to display them in real time on the computer. The system presented has the potential to teach several experiments in thermodynamics thanks to its reliability in measurements, low cost and a good level of accuracy. It is therefore an innovative, modern and affordable teaching tool that offers students the possibility to reduce the duration of the experiment much more than the traditional method.
