VEML6070 UV Sensor With Nokia 5110 LCD

After sitting 3 months on this project i thought i share it with the maker community. A budget price UV sensor :)
It can be assembled within 1 hour and can use it for years.

The UV Index scale is a great tool to tell you how quickly sunburn can occur if you are not applying proper protection. The ultraviolet levels are measured on a daily basis by the National Weather Service and then are converted to a scale of exposure risks.

0-2: Low
A UV Index reading two or lower means there is a minimal risk of sunburn for the average person. At this level it is suggested to wear sunglasses, use broad spectrum sunscreen and watch out for bright surfaces like sand, water and snow which reflect UV rays, increasing your exposure. The time to burn can vary by skin type, but at a low UV level it is approximately 60 minutes.

3-5: Moderate A UV Index reading between 3 and 5 means there is a moderate risk of sunburn for the average person. At this level it is suggested to seek shade between 10AM and 4PM when the sun’s rays are its strongest. Wearing protective clothing, including a hat and sunglasses, is a great way to limit exposure. Sunscreen should be applied every two hours, even on cloudy days, and reapplied after swimming or sweating. The time to burn can vary by skin type, but at a moderate UV level it is approximately 30 to 45 minutes.

UV INDEX CHART6-7: High A UV Index reading 6 or 7 puts you at a high risk of harm from unprotected sun exposure. Following the steps from the moderate level is suggested. The time to burn can vary by skin type, but at a high UV level it is approximately 15 to 25 minutes.

8-10: Very High A UV Index reading 8 to 10 puts you at a very high risk of harm from unprotected sun exposure. Take extra precautions for both your skin and eyes because damage occurs quickly, typically within 15 minutes. Try to minimize your sun exposure during peak sun times, but if not possible then diligently apply and re-apply sunscreen and SPF lip balm.

11 or more: Extreme A UV Index reading 11 or higher puts you in a very dangerous spot for sunburn with damage occurring in less than 10 minutes if unprotected. At this level it is best to avoid all sun exposure between 10AM and 4PM.

Find out the UV Index Level near you and protect yourself from damaging skin exposure. Research has shown that getting severe sunburn, just once every two years, can triple the risk of melanoma skin cancer.

Try to avoid sun exposure between 10 a.m. and 4 p.m.
If outdoors, seek shade and wear protective clothing, a wide-brimmed hat, and UV-blocking sunglasses. Generously apply broad spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating. Watch out for bright surfaces, like sand, water and snow, which reflect UV and increase exposure. The Shadow Rule An easy way to tell how much UV exposure you are getting is to look for your shadow:

If your shadow is taller than you are (in the early morning and late afternoon), your UV exposure is likely to be lower. If your shadow is shorter than you are (around midday), you are being exposed to higher levels of UV radiation. Seek shade and protect your skin and eyes.”
