Abstract
U diplomskom radu je opisano i izrađeno sklopovlje i programska podrška uređaja male potrošnje za nadzor kvalitete zraka. Kako bi se napravio uređaj za nadzor kvalitete zraka, odabrani su onečišćivači koji najviše utječu na kvalitetu zraka. Za mjerenje NO2 i CO plinova kao najznačajnijih onečišćivača odabrani su elektrokemijski senzori, a uz plinove mjeri se i količina lebdećih čestica. Za senzore, komunikacijski modul i mikrokontroler napravljena je tiskana pločica kako bi se dobio kvalitetniji i bolji uređaj koji je otporniji na vanjske smetnje. Kako bi se podaci sa senzora mogli pročitati, napravljena je programska podrška za uređaj koja upravlja sa svim senzorima i komunikacijskim modulom. Za slanje podataka u oblak odabrana je NB-IoT komunikacija koja je namijenjena za slanje male količine podataka uz malu potrošnju energije. Također su napravljeni i dijagrami u oblaku za svaki podatak te je time olakšano čitanje podataka, a osim čitanja podataka u oblaku je moguće implementirati i slanje podataka u druge baze gdje se podaci dalje mogu obrađivati i analizirati. Nakon izrade uređaj je testiran, a mjereni podaci su uspoređeni s lokalnom mjernom postajom te je potvrđeno da uređaj zadovoljavajuće točno mjeri podatke uz odstupanje od 2 posto za mjerenje koncentracije plinova i manje od 1 posto za ostale parametre.
Abstract (english)
Circuitry and software developed for a low-power air quality monitor is described in this graduate thesis. In order to achieve the best possible readings, pollutants that affect the air quality the most have been selected. For NO2 and CO measurement, electrochemical sensors are used, alongside particulate matter sensor. To accommodate sensors, communication module and microcontroller, custom made PCB is designed and manufactured. That way, the device can endure harsher outside environmental conditions with increased noise immunity. To read data from the sensors, special firmware runs on a microcontroller, which takes care of sensor readings and communications. NB-IoT is used to transmit readings to the cloud, since it's more energy efficient for such small amounts of data. Furthermore, the cloud system includes convenient graphs and the same data is ready to be transferred to another database for further analysis. After prototyping, the device was taken through the testing point where its readings were compared to the local metro 30 station. Readings were appropriate, with 2% deviation for gas pollutants and 1% deviation for other parameters.
