Abstract

Sažetak: U diplomskom radu opisano je razvijeno rješenje mjernog sustava za određivanje temperature i relativne vlažnosti zraka namijenjenog za primjenu u laboratorijskom prostoru. Sustav se sastoji od fizičkog modela temeljenog na Arduino mikrokontroleru te korisničke aplikacije napravljene u programskom alatu LabVIEW. Sustavom se upravlja pomoću LabVIEW aplikacije s ekrana računala. Za mjerenje temperature koriste se termistor te digitalna osjetila DHT11, DHT22 i SHT31, koja se ujedno koriste i za mjerenje relativne vlažnosti zraka. Predloženo rješenje ispunjava zahtjeve na relativno nisku cijenu izgradnje, jednostavnost korištenja te zadovoljavajuću točnost, koja se može i poboljšati umjeravanjem svakog uporabljenog osjetila. Buduća nadogradnja bi ići upravo u tom smjeru.

Abstract (english)

The graduation thesis describes a developed solution for measuring temperature and relative humidity of the air intended for use in the laboratory for electrical measurements. The system consists of a physical model based on the Arduino microcontroller and user application made in LabVIEW software. The system is managed using the LabVIEW application from the computer screen. For temperature measurement, the thermistor and digital sensors DHT11, DHT22 and SHT31 are used for temperature measurements. All three digital sensors are used for measuring the relative humidity of the air, as well. The proposed solution meets the requirements at a relatively low cost of production, ease of use and satisfactory accuracy. Future upgrade should be in the direction of achieving better accuracy.
