Abstract
Tema ovog rada je bila osmisliti mreţu senzora koji se baziraju na radio primo-predajniku s nRF24L01(+) integriranim krugom. Potrebno je bilo detektirati da postoji prepreka, odnosno pokret, te preko Bluetooth™ veze obavijestiti korisnika putem pametnog telefona. Detekcija pokreta je izvršena pomoću SRF-05 ultrazvučnog senzora udaljenosti , te se prati da li je izmjerena udaljenost koja je primljena paketom na glavnu jedinicu veća ili manja od one koja je podešena kao okidna udaljenost. Ako je manja, korisnika se obavještava putem zvuka i informacije prikazane na pametnom telefonu. Mreţa senzora je beţična i prijenosna, dakle napaja se preko baterije. Također, ugrađeno je i mjerenje temperature i vlage zraka pomoću DHT22 senzora temperature i vlage koji koristi jednoţičanu komunikaciju s mikroupravljačem. Pošto su jedinice beţične, napajanje baterijom, potrebno je i pratiti stanje baterije i upozoriti korisnika ako su prazne, što je izvedeno pomoću djelitelja napona i analogno-digitalnog pretvarača ugrađen u mikroupravljač. Korisnik ima mogućnosti podešavati postavke slanjem naredbe preko Bluetooth™ veze.
Abstract (english)
Task of this project was to make a sensor network that are based on radio transceiver with nRF24L01(+) integrated circuit. It is necessary to detect whether an obstacle or motion exist and then over a Bluetooth connection notify a user using his Smartphone. Motion detection is done by using SRF-05 ultrasonic distance sensor and it monitors measured distance that is received by main unit, sent by sensor unit and comparing whether is that distance bigger or smaller of trigger distance, which is set by user. If it’s smaller, user gets notified by sound on main unit and information shown on his Smartphone. Sensor network is wireless and portable, so it gets supplied from DC battery. Oslo, there is a temperature and humidity measurement of air, done with DHT22 air temperature and humidity sensor. Because, all units are wireless and portable , supplied by DC battery, it is necessary to monitor battery voltage and notify a user if batteries are getting low, which is done by using a voltage divider and analog-to-digital converter that is built-in inside a microcontroller. User can change setting sending a command over Bluetooth network.
