Bezdrátové měření analogových veličin pro chytré mobilní zařízení

Abstract

This bachelor thesis aims to create the device used for wireless analogue signal measurement that is transported to Smartphone with Android operation system using Bluetooth technology. First part of this thesis was concerned with the creation of device that is capable of voltage measuring. This device would have two channels for analogue signals measurement.The AtMega8 microcontroller from Atmel company is the main part of this device. BTM112 module from Rayson company is the main radio module. The program for Atmega8 microcontroller was written in C language and it communicates with the Bluetooth module using AT commands. The second part of this thesis was to study and use Java programming language for Android's client visialization application The application can process and display signals from both channels and display them on the screen of the smartphone device.
