Abstract
Bežični senzorski čvorovi koriste se u raznim područjima ljudskog djelovanja, a služe za prikupljanje, obradu i slanje podataka radi boljeg nadzora i kontrole nad raznim sustavima. Karakteriziraju ih niska potrošnja i cijena te rad u zahtjevnim okolišnim uvjetima. U sklopu ovog rada izrađen je cjelokupni sustav za udaljeno prikupljanje podataka putem senzorskih čvorova povezivih na Wi-Fi mrežu. Za realizaciju senzorskog čvora korišten je ESP32 mikrokontroler, na koji je za potrebe demonstracije povezan BMP280 senzor putem I2C sučelja. ESP32 mikrokontroler je odabran jer sadrži integrirano Wi-Fi sučelje i omogućuje izradu složenih IoT aplikacija, s posebnim naglaskom na sigurnost. Za razvoj programske potpore za ESP32 mikrokontroler korišteno je razvojno okruženje ESP-IDF. Za prihvat senzorskih podataka korištena je baza podataka InfluxDB, a Grafana za grafički prikaz senzorskih podataka na web stranici. Kako bi se povećala sigurnost sustava, za komunikaciju senzorskog čvora i servera korišten je HTTPS protokol.
Abstract (english)
Wireless sensor nodes are used in various areas in order to collect, process and provide data for remote monitoring and control of various systems. They are characterized by requirements for low power consumption and low price, as well as a need for functioning in demanding environmental conditions. In this work a complete system for remote data collection via sensor nodes with Wi-Fi connectivity was developed. ESP32 microcontroller was used for implementation of the sensor node, with BMP280 sensor interfaced via I2C bus for demonstration application. The ESP32 microcontroller was chosen because it features an integrated Wi-Fi interface and enables development of complex IoT applications, with a particular emphasis on security. ESP-IDF development environment was used to develop software for ESP32 microcontroller. InfluxDB database was used to store data from sensors, while Grafana was used to graphically visualize sensor data in web interface. HTTPS protocol was used to provide better security for communication between sensor node and the server.
