Caracterización e instrumentación de sensores de ultrasonidos

Abstract

The purpose of this project is to limit the characterization and implementation of an ultrasonic sensor modeled by Mr. César Briso Rodríguez.
Once the sensor modeling by simulating physical characteristics and electrical characteristics, we proceed to the instrumentation and use. This section includes
electronic instrumentation that would be necessary for the piezoelectric excitation in the emission mode and for receiving electrical pulses generated by the sensor in
response to the received echoes, and matching signal levels right to acquire, in the reception mode.
After the adjustment of the signals for the acquisition, these signals will be digitalized, processed and represented on the screen on a PC through a data acquisition card by USB port. Acquisition card is able to sample the response signals and transmit the samples to representation and control software developed in this project. The user interface, the acquisition card control software and processing and representation software has been developed with Visual Basic 2008 and OpenGL graphical libraries.
