Diseño y construcción de un instrumento electrónico para la detección y cuantificación de campo magnético, como método de alfabetización para docentes de física

Abstract

In this paper the design and construction of an instrument for measuring magnetic field, developed in six phases, which consist shown: characterization UGN3503 Hall effect sensor Allegro manufacturer, digitization of the signal provided by the sensor through the analog to digital converter of PIC microcontroller 16F877A, calibration of the measuring instrument, the development of software for data acquisition, hardware building consisting of printed circuit assemblies and electronic components communicate with the computer through the RS-232 serial interface. This work is done in order to provide tools that contribute to scientific and technological literacy of teachers of physics, allowing them to develop skills in the use and application of electronic components, programming languages, laws of physics and mathematical tools, for the construction of measuring instruments for use in the teaching of science or experimental space research.
