Introduction/about

For this project I proposed, developed and tested a hardware module based on an Arduino Uno microcontroller and wireless technology via the WebSocket protocol, which measures the openness of Croatian mussels. This information is received by a specially designed application interface that runs on a personal computer connected via a wireless connection.

The build involved designing and planning the components to be used, as well as wiring and soldering everything into a working device. Then the microcontroller is programmed to be able to recive readings from the selected sensors and communicate to the outside.

Idea came from creating connection with constant data transfer between server and microcontroller as client, that's where the name of project "Module for continuous sending" originates from. For it, most fitting comunication protocol appeared as websocket, because of providing full-duplex communication channels over a single TCP connection. After that it got plenty of aditional features like GUI and all actions with it.

It's primary use is to work with analog HALL sensors which are connected to Croatian mussels, givng us complete monitoring of state and measure how open the mussels are. Monitoring of such has plenty of enviromental benefits because mussels react on bad conditions of water, making them ideal bioindicator.
