Hi there! This is my first TB. It is called Sunaware and here is it's story.
This TB let's you measure UV radiation. It want's to go to places where radiation is high (see attached map) to inform people that to much UV radiation is very harmful.
Measure the radiation by placing the TB in daylight for one minute at the spot where you discovered, picked-up of left the TB. The TB likes it when you log your UV reading together with the time. It would be great if you can support it with a photograph!
If you measure at least -middle-, the TB advices to look for shade or to use a high sun factor! Be careful with sunlight!
