Supplementary Material: Low-Cost Wearable Dive Computer for Monitoring, Logging and Presentation of Large-scale Freediving Studies

On the other hand, there is the underwater world, in which technological development could not progress so quickly; mainly because the sealing of the device and the interaction with it, pose different and novel problems compared to more widespread wearables.

To close this gap, a low-cost dive computer with a customizable set of sensors which is suitable for large-scale data collection for divers is presented in this contribution. This prototype makes use of existing electronic components such as sensors or modules aimed to develop a fully functional and low-cost portable system. In addition, the portable system is also able to store the data of all users bundled on a server for further research.
