Multi-senzorový digitální teploměr

Abstract

This bachelor work deal with creation thermometer with multiple sensors. Thermometer contains five 1-Wire buses, at what we can connect sensors Dallas DS18b20. When is connected power supply or device is reset, thermometer go over all buses and find out connected sensors. Thermometer displays temperature of selected sensors on LCD. Next function of thermometer is working with groups of temperature sensors, which can compute average temperature. Thermometer supports connecting to PC by USB and provides measured temperature and average temperature. Display temperatures on PC allow PC application, which can configure thermometer and define groups of sensors. The main part of thermometer is microcontroller Atmel ATmega8L, which controls other electronic device and communicates with temperature sensors. The communication between microcontroller and USB is provided by converter FTDI Chip FT232RL.
