POTALTI | Let's go to the Beach!


Awards & Nominations

POTALTI has received the following awards and nominations. Way to go!

Global Nominee

The Challenge | Let's go to the Beach!

Build a tool for beach-goers to monitor for hazards and to alert them of precautionary measures for protection on their swim- and surf-filled adventures!

Internet Of Beach

Satisfy your curiosity about beaches to go! IoB wristband warns you about dangerous amounts of UV exposure with respect to your skin sensitivity, age and how much actual radiation you received.


We designed a web application, an IOB wristband a gateway and a server. With our web application, many information about the beach can be learned. Required informations are taken from openweather api and are showed to users with open board dashboard. The time of the UV exposure of the person is measured with IOT wristband. The required informations and energy are provided from solar panel. RGB leds warn you with processing data from the cloud. We also designed a gateway which is shaped as a buoy and placed it to the beaches to connect IOB wristband to cloud. More reliable data are obtained with processing all these data in cloud.

It's hard to introduce everybody one by one. But in a nutshell we are enthusiast about space, electronic, software and all flying things. Also two members of our team joinder at 2015 Nasa Space Apps Challange Istanbul and they were selected as People's choice with Christopher Team.

# What is The Challange?

Let's go to the Beach!

According to the World Health Organization [1], overexposure to sunlight can cause harm to our skin, our eyes, and our immune systems. In fact, protecting ourselves from UV damage, for example by using hats, sunglasses, and sunscreen, can prevent four out of five cases of skin cancer.

Our soution covers most of challange as below.

- [x] Predict their sun exposure

- [x] Suggest alternative times of the day, or days when sun exposure levels are lower

- [X] Warn users of presence of HABs in local beaches, and direct them to safer regions, where available

- [x] Add other precautionary and safety alerts as you see fit!

# What is The Solution?

APP + IoT Band + Cloud!

IoT Band:

Gateway between IoT Band and Cloud Server

Cloud Server

# How its Working?

For better describition, you can watch project video.

# Thank you for your time

We are to happy to participate this contents. We hope we will join next year again. By the way, you can see technologies which we used while hackathon process.

I want to finish with a quote from Richard Bronson.

Above all, we want to create something we're proud of.
