A project was developed that introduces an automated underwater buoyancy balance system. This allows divers to select a target depth or a diving plan, and the system ensures they reach that specific depth without manual balancing.
In the initial phase, a diving environment was simulated. This posed challenges, particularly in sealing the depth sensor. Subsequently, a model was designed to replicate open water conditions and a sealed diving vest.
An Arduino Nano was utilized to create a digital control prototype that emulates the buoyancy mechanism of a diver. The system continuously measures the diver’s depth and decides whether to inflate or deflate an attached balloon based on this data. To improve the user experience, a diving program, buttons, and a display were integrated. This enables divers to monitor their current depth and set their desired depth.
