The diploma thesis presents the development of temperature gauge with the option of storing data on the SD card. These data are the temperature and the time in which the temperature was measured.
In diploma thesis characteristics of individual machine parts of data logger and the development process of software code for operation of the individual elements that make the data logger as a whole are described.
The introduction contains descriptions of the elements (PIC18F8627, RTC, LCD, AD595, SD card) and the planning and execution of circuit boards.
The main part is formed by two sections. The first section describes the collection and presentation of data and the second one describes data storage on the SD card.
The final section describes the measurements made during the practical test of temperature gauge with the option of storing data on the SD card. During the practical test is also found relevance of the completed conditions set out in the introduction.
All software code was written in C programming language in the development environment MPLAB IDE
