Project Overview

Manta Mask is an Internet of Things project. The inspiration for this project is from a friend of mine, who suffered from terrible decompression sickness because they surfaced too quickly when scuba diving. This mask aims to prevent this by giving the wearer visual cues of when to ascend and when to wait, ensuring they return to the surface safely.

The bulk of this project is focused not on the mask itself, but on the mobile application that would accompany it. With the app, a user is able to plan a trip, get information and advice, and then transfer that information to their mask. Upon completion of a dive, the mask will then upload information back to the app and help keep a log.

The Problem

Background Research (The Science)

Why does pressure change underwater? The deeper you dive the higher atmospheric pressure you’re in. When diving deeper the volume of air will get smaller and the olecules in those spaces will become more compact. Since water is denser than air, greater changes in ambient pressure occur underwater. Every 33 feet of depth adds the pressure of another atmosphere to the ambient pressure. This is called 1 ATM (atm standing for atmosphere) Divers use this information to plan their dive trip effciently and accurately. This also helps them calculate how much air they will need.
