Abstract

Kreirana su dva projekta: ESP32_Pošiljatelj i ESP32_Prijemnik. Unutar prvog projekta nalazi se ESP32 mikrokontroler na kojeg su spojeni senzor temperature i vlage zraka, senzor vlage tla i LoRa modul. Senzori su spojeni na pretvornik napajanja, koje je služilo kao dodatno napajanje, te su prikupljali podatke i slali ih ESP32 mikrokontroleru. Nakon obrade podataka, mikrokontroler komunicira sa LoRa modulom koristeći SPI protokol i šalje podatke drugom dijelu projekta. Drugi dio sastoji se od ESP32 mikrokontrolera koji ima LoRa modul i LCD ekran. I2C protokolom mikrokontroler šalje i ispisuje podatke na LCD ekranu. Projekti su međusobno povezani preko LoRa modula koristeći LoRa komunikacijsku tehnologiju.

Abstract (english)

Two projects were made: ESP32_Sender and ESP_Receiver. First projects includes ESP32 microcontroler on which are connected air temperature and humidity sensor, soil moisture sensor and Lora module. Sensors were connected to power converter, that served as additional power supply, and collected dana which was sent to ESP32 microcontroller. After data processing, microcontroller comunicates with Lora module using SPI protocol and sends that dana to second part of the project. The second part consists of an ESP32 microcontroller that has a LoRa module and an LCD screen. With the I2C protocol, the microcontroller sends and prints data on the LCD screen. The projects are interconnected via LoRa modules using LoRa communication technology.
