SwimDawg

The SwimDawg is a wristband that accompanies any swimmer to ensure their safety when lifeguards are not immediately present

The Team's Philosophy:

this project aims to united our knowledge with real-life application. Our goal is to help the community with devices that in this project specifically means to provide security. Our targeted customers are children and children's parents, as well as swimming centers that are willing to install this project in an attempt to provide their customers with greater security.

Project Description:

A Swimdawg is a coordinated system with a response center and multiple trackers. The trackers are implanted in wristbands that can be worn by the swimmers. When the pressure sensor implanted in the wristband on a specific swimmer has reported under water (the default setting is 1.5 meters) for longer than 2 minutes, the tracker will send a signal information to the response center that denotes the specific wristband's index number. The lifeguard will be notified by the response center and take necessary actions.

Building process:

a. Material and equipments: Arduino micro-controller (x2), HC-12 RF (x2), MS-5803 pressure sensor (x1)

b. Coding for the response center and for trackers' micro-controllers

c. Connect the wires and hardware

d. Solder the micro-controller with electronic units

c. Case design

Challenges

a. The use of HC-12 actually first worked on Teensy, and we had to recode the RF transmitters

b. The pressure sensor needs waterproof casing

What's Next for SwimDawg

a. Adaptation into systems with more functions, for example an automatic gas tank that floats

b. Adapt the interactive system for more diverse situations, for example fire-alarm
