Abstract

Zbog modernog načina života ljudi sve više borave u zatvorenim prostorima, bilo to u
vlastitom stambenom objektu, na poslu ili u prijevozu pa samim time i kvaliteta zraka
postaje sve važnija tema. U zatvorenim prostorima može doći do značajne razlike u
temperaturi i vlažnosti zraka, koncentraciji prašine, lako hlapljivih spojeva te razini
radioaktivnosti u odnosu na okolinu. Upravo je zato važan monitoring navedenih
fizikalnih parametara kako bi se ustanovio njihov utjecaj na ljudsko zdravlje. U ovom je
radu korišten senzor DHT22 za mjerenje temperature i vlažnosti zraka, GeigerMüllerov
brojač za mjerenje radioaktivnog zračenja te kalibrirani uređaj Airthings Corentium Pro
za mjerenje temperature, vlažnosti i tlaka zraka te koncentracije radona. S obzirom na to
da je Airthings Corentium Pro kalibriran za mjerenje koncentracije radona, naglasak rada
je na mjerenju radioaktivnosti u zatvorenom prostoru i njezinom utjecaju na ljudsko
zdravlje. Spajanjem senzora na Croduino, hrvatsku verziju mikrokontrolera Arduino,
omogućeni su različiti načini snimanja podataka poput snimanja podataka na računalo
pomoću programskog jezika Python, slanja na platformu ThingSpeak putem interneta i
snimanja na SD karticu. Sva su mjerenja izvedena u prostorijama Geotehničkog fakulteta.
Analizom rezultata mjerenja sa senzora i usporedbom s Airthings Corentium Pro
utvrđeno je da senzori nemaju velika odstupanja.

Abstract (english)

Due to modern way of life people increasingly spend their time in closed spaces,
whether in residential buildings, at work or in transport, and therefore the topic of air
quality is becoming more important. There can be a significant difference in indoor air
temperature and humidity, the concentration of dust, volatile organic compounds and
radiation level in comparison to the environment. That is precisely why monitoring of
indicated physical parameters is important in order to establish their effect on human
health. In this paper, a DHT22 sensor was used to measure air temperature and humidity,
a GeigerMüller
counter was used to measure radioactive radiation and a calibrated device
Airthings Corentium Pro was used to measure air temperature, humidity and pressure as
well as a radon concentration. Since the Airthings Corentium Pro is calibrated to measure
radon concentrations, the emphasis of the paper was placed on measuring radioactivity
indoors and its effect on human health. By connecting the sensors to Croduino, a Croatian
version of an Arduino microcontroller, various ways of recording data were provided
such as being recorded on a computer by using the programming language Python,
sending to the platform ThingSpeak via the Internet and recording on an SD card. The
measurements were performed on the premises of the Faculty of Geotechnical
Engineering. By analysing the results of measurements performed by using sensors and
by comparing them to the Airthings Corentium Pro device it was determined that the
sensors do not deviate significantly.
