The product could be a sun protection material in the form of a liquid, cream or lotion or other materials in the forms of medicines, food, toiletries etc. The device may alert the user when exposed to ultraviolet radiation for a specified period, that they need to re-apply the sunscreen material, thus reducing the risks associated with over exposure to UV radiation. The monitoring device may also indicate to the user that the product is at or has gone beyond its expiration date and helps prevent use of the product before it becomes hazardous.
