Abstract

Jedan od načina beskontaktnog mjerenja temperature je pomoću termičkih senzora. Način rada termičkih senzora je osnovan na slijednoj pretvorbi termičkog zračenja u toplinu, i zatim konverziji toplinskih razina ili toplinskog toka u električni signal. Dvije vrste termičkih detektora koje su korištene u ovom radu su piroelektrički i thermopile senzori. Thermopile senzori generiraju napon kada postoji razlika u temperaturama vrućeg i hladnog kraja. Piroelektrički senzori napon generiraju na temelju piroelektričkog efekta. Od piroelektričkih senzora korišteni su IRA-S210ST01 i AMN31112J, a od thermopile senzora korišteni su G-TPCO-019 i G-TPCO-035. Za projektiranje tiskanih pločica za senzorske čvorove korišten je programski alat Altium Designer. Spajanjem četiri senzorska čvora na razvojni sustav STM32F4 Discovery Board ostvaruje se komunikacija između senzora i računala. Kako bi komunikacija bila moguća potrebno je inicijalizirati odgovarajuće komunikacijske protokole i napraviti analogno-digitalnu pretvorbu. Za programski dio rada korišteno je razvojno okruženje Keil μVision.

Abstract (english)

One of the methods for the temperature measurement is by using thermal detectors. Thermal detector’s operation mode is based on sequential conversion of thermal radiation to heat, and after that conversion of thermal levels or thermal flux in voltage. Two types of thermal detectors used in this work are pyroelectric and thermopile detectors. Thermopile detectors generate voltage in case of temperature difference between hot and cold junctions. Pyroelectric detectors generate voltage on the principle of pyroelectric effect. In this thesis, we used pyroelectric sensors IRA-S210ST01 and AMN31112J and thermopile sensors G-TPCO-019 i G-TPCO-035. The printed circuit boards (PCB) were designed by usage of software package Altium Designer. By connecting four sensors node on developing system STM32F4 Discovery Board, communication between sensor and computer was realised. For communication realisation, initialization of an appropriate communication protocol and usage of analog to digital conversion are needed. The firmware was implemented using development tools Keil μVision.
