24 hours. Nineteen teams. Three cases. Our weekend was kicked off to an inspiring start at the Code4Good Hackathon. The team came together to create an inventive technology that could help increase awareness of the damage sunburns causes to skin and the increased risk of getting skin cancer it induces tailored to children aged 4-12.

Together with the Dutch Cancer Foundation (KWF), the various teams used their innovative spirits to find solutions to the most effective form of protection, regardless of the subject, increasing awareness.

Ensure children’s awareness of the importance of sunscreen.

Before the start of the hackathon, we researched kids’ habits regarding sunburn prevention. We asked several of our colleagues’ children various questions, such as:

– Have they ever had even been sunburnt?
– Do they know when and how to use sunscreen?
– Do their parents ever tell them to seek protection from the sun?

Let the hacking commence!

On Friday, the hackathon kicked off with nineteen teams and three cases. We were in a group with six other teams working on the children sunscreen use case. Shortly after a Q & A session with Kim Kruijt from the KWF, the hacking began!

The first order of business was ensuring a mutual understanding within the team of the case and what we needed to do to find an effective solution. Naturally, we used Design Thinking methodology for this brainstorming session.

Our Solution:

A physical button for the child that measures the UV strength and an app for the parents to keep track of when the child needs to put on protective clothes or start wearing sunscreen.

Technical Solution:

We came up with a sensor that picks up the local UV index, which is connected to a raspberry Pi. The Pi used a python script to read and send the data to the SAP Cloud Platform back-end, which saved the data in a HANA database. This database was then fed into several services which powered the data of the UI5 app.

KWF Application

 In the app, you could see the current UV index as indicated by the RIVM, as well as the index that is measured by the sensor. The app could also send a native push notification when the server receives a signal that the measured UV strengths spikes, reminding the parent to make sure the child is well protected from the UV rays.

The app also has a statistics feature that calculates the total amount of UV radiation that the child has been exposed to and how this exposure will influence the risk of getting skin cancer later in life.

This application could help parents monitor their children’s UV exposure. It will increase the awareness

of the adverse effects of not using adequate sun protection and serve as a helpful reminder of when to (re)apply.

This was a really great opportunity, to not only combine the various technical expertise among colleagues, but also look at how we could apply our skills in an impactful way to make a change for the better. Although it took some time to catch up on our sleep from the weekend, man, are we happy to have been a part of it!

We are always inspired by projects that allow us to think in an innovative manner to solve problems, from improving sunscreen use, to clean energy. Do you have a project that needs a technical solution? Reach out to us and together we can see how we can push the edge of innovation further!
