This book provides an automated experimental analysis of the behavior of a thermoelectric cell used to generate electricity. When subjected to different temperatures on its faces, a cell measuring just 40 millimeters produces an electromotive force capable of providing power of more than 100 milliwatts. The details of the construction of the bench, the equipment used, the control strategy, the calibration of the sensors, the analysis interface, the measurement procedures and the results obtained are all available to the reader through detailed information, tables, photos, graphs and diagrams, in a way that makes it easy to understand.
