Resumen
For this work, a microcontrolled system has been described for rotation and temperature data acquisition on motor fan used in Frost Free refrigerators designed by Electrolux. For this acquisition system development the following components have been used: a PIC16F877A microcontroller, a LM35 sensor, an infrared LED and a phototransistor. The suggested system reached deviation lower than 1% comparing to the current methodology, mainly on the band operation that the given company uses for testing their models, which is from 1800 to 3100 RPM. According to the several performed trials it was possible to verify that the proposed system performed in a reliable and suitable way for the required application.
