Agritech

This project is part of my internship at University of Bologna, bachelor degree in Computer Science (a.y. 2022/23).

Concept

The project is inside the src directory and it is split into:

• enddevice, Arduino sketch(es) used for controlling sensors, collecting data and sending them over LoRaWAN protocol to gateway(s)
• gateway, Arduino sketch(es) for forwarding data from LoRaWAN to the server over MQTT protocol
• server, Go software for collecting data from the MQTT broker, process them and save to the DB. It also serves a web interface for displaying collected data and its API

Setup

enddevice and gateway

For these two folders make sure to install all the required libraries. You can edit ./src/gateway/credentials.h (at first you need to copy it from ./src/gateway/credentials.h.template) to set up the gateway(s) connection to WiFi and MQTT broker.

You can edit sensors pins and setup at ./src/enddevice/read_data.h.

Usage

enddevice and gateway

After setting up, you can compile and upload gateway.ino and enddevice.ino sketches to the boards you're using.

This project is based on Heltec LoRa 32 v3 boards.

server

From the main folder you can use docker-compose up -d to host 3 docker containers:

• the server, written in Go, available at ./src/server/ and running at port 8080
• the MQTT broker, which configuration file is available under ./config/mosquitto/ and running at port 1883
• the MySQL database, running at port 3307

You can edit these configurations inside docker-compose.yml.

The web app is running at {HOST_IP}:8080/web and its API is available at {HOST_IP}:8080/api.
