Abstract

Istraživanja u kontekstu praćenja klimatskih promjena, procesa u okolišu i druge primjene pored ostalog imaju potrebu sustavnih mjerenja brzine i smjera strujanja zraka. U ovom radu dan je prikaz postupka konstrukcije ultrazvučnog anemometra namijenjenog takvoj primjeni; za izradu anemometra odabrana je Arduino platforma. Za kalibraciju anemometra korišten je jednostavan zračni tunel koji je omogućavao brzine do 2.7m/s. Izrađeni uređaj pokazao se funkcionalan, premda preciznost mjerenja nije adekvatna za praktičnu primjenu. Objasnjena su poboljšanja u metodi detekcije, kao i u kalibraciji, kojima bi se moglo poboljšati preciznost uređaja.

Abstract (english)

Research in the context of monitoring climate change, environmental processes, and other applications, among other things, needs systematic measurements of air velocity and direction. In this paper, the construction procedure of an ultrasonic anemometer intended for such use is presented; the Arduino platform has been chosen for the construction purposes. A simple wind tunnel providing wind speeds up to 2.7m/s has been used to calibrate the anemometer. The designed device proved to be functional, although its measurement precision is inadequate for practical use. Improvements in detection method, as well as those in calibration, that would improve the device precision are explained.
