Tarjeta de adquisición de datos con comunicación inalámbrica

Abstract

This paper presents the design and implementation of a data acquisition card with wireless communication. Brewed in order to provide a device that provides us tools when making decisions, making these more reliable and without limitation, ideal for electrical and physical small-scale measures, providing a variety of uses and applications at low cost. The initial stage of it is composed of 4 input channels, each with different characteristics which can be selected from the graphical interface. Subsequently a stage of amplification and filtering of the signal which acts preventively to the introduction of higher frequency signals that can affect the microcontroller, followed this signal is input to an analog-digital converter to sample it is going to be quantified and in turn sent wirelessly by the HC-06 module, the signal displayed on a graphical user interface displayed on an LCD the current input and the amplifier gain since 4 types of profit will be available, providing additional help and in the case of very low signals will facilitate the analysis and control of this.
