Abstract

U ovome radu prikazana je izvedba sustava automatskog zalijevanja za potrebe zalijevanja biljaka u stakleniku.

Kako bi se započela realizacija ovakvog sustava bilo je potrebno napraviti detaljan plan svih čimbenika koji utječu na sam raspored zalijevanja. Potrebno je odrediti temperaturu zraka, stanje vlage u tlu i zraku te koje je godišnje doba u trenutku zalijevanja. Za mjerenje vremenskih uvjeta potrebno je preuzeti podatke sa senzora za mjerenje temperature te pomoću Real Time Clock (RTC) se može očitati točno vrijeme i datum. Za mjerenje vlage potreban je senzor vlage koji će prikazivati trenutačno stanje. Cijelim sustavom upravlja mikrokontroler za koji je izrađen detaljan dijagram tijeka algoritma za zalijevanje. Osim same elektronike, razrađen je i sustav transporta vode od spremnika do biljaka.

Kako bi konačni proizvod bio konkurentan na tržištu, cijena pojedinih dijelova mora biti što manja. Dana je usporedba trenutačnih sustava sa realiziranim sustavom.

Abstract (english)

This thesis presents the implementation of an automatic irrigation sytem for the purpose of watering plants in a greenhouse.

In order to start the realization of such a system, it was necessary to make a detailed plan of all the factors that affect the watering schedule. It is necessary to determine the air temperature, the state of moisture in the soil and air and what time of year at the time of watering. To measure the weather conditions, it is necessary to import the data from the temperature sensor and use a Real Time Clock (RTC) to read the exact time and date od the day. A moisture sensor is needed to display the current state of moisture in a soil. The whole system is controlled by a microcontroller for which a detailed flowchart diagram of a watering algorithm has been made. In addition to the electronics, a system for transporting water from storage tanks to plant beds has been developed.

In order for the final product to be competitive on the market, the price of individual parts must be as low as possible. A comparison of present-day systems with the envisioned system is given.
