Měřicí karta s Bluetooth low energy

Abstract

This bachelor thesis deals with designing a Bluetooth Low Energy Measuring Card. First part of this thesis describes the concept of Bluetooth Low Energy and selection of the Bluetooth module. Afterwards the structure of designed GATT for communication between BGM113 module and Android smart device is described. Subsequently the firmware for BGM113 module is introduced which enables measurement of temperature and relative humidity using digital sensor, furthermore analog to digital conversion is made possible. After that the Android application is presented. This application allows users to visualize and export data and set up measurement parameters. Lastly measurement results and energy profiles are presented, along with the graphical users interface of the application.
