Practical UV Sensor Background: UV ray detection is becoming a concern for many people. The awareness of the effects of solar UV rays on skin has created a demand for proper protection. With proper protection, individuals can shield themselves from many skin diseases. UV sensing technology currently exists (i.e. the UV index used in weather reports), but for the most part is not used on a practical, individual basis. If a device was created to show people how damaging the UV rays are, they will likely take better steps to help protect themselves. Problem Statement: Although technology exists to show people the intensity the UV rays, there are no current products people can use on an individual basis. Most weather reports give a UV index, but most people do not know how to correlate the index with how much protection is needed. Therefore, there is a need for a product that can give people access to information concerned with individual protection. There is a need and a practical solution to meet it. Our solution will require the use of light sensors, a small microchip to analyze the data, and computation of the recommended SPF. From there, the output will be displayed. The display portion of the module has not yet been determined, but at this point, a seven segment display or a series of LED’s has been proposed. The display will clearly point out to the user what SPF of sunscreen they should use for full protection. The module itself should be portable and inexpensive. In all, the purpose of this device is to both protect and educate the average person about skin protection from the sun.
