Real-Time UV Exposure and Vitamin D Tracking for Personalized Health Monitoring with Alerts for Safe Exposure Limits

Excessive exposure to ultraviolet (UV) radiation poses significant health risks, necessitating the development of advanced monitoring systems for personalized health management. Research has shown that UV exposure is an inevitable part of a healthy and active lifestyle and helps in combating the novel coronavirus. On the other hand, excessive UV exposure can lead to a plethora of other diseases like cancer, lupus flares, and cataracts. This research work aims to develop a UV index monitoring device that measures cumulative UV exposure and tracks vitamin D absorption in real time while providing alerts before overexposure. This enables the user to fine-tune how much UV exposure they manage in a given day, based on clinically validated limits for different skin types/colors. The developed model is capable of measuring the UV index with high accuracy even in brightly lit areas, as it mimics the human skin’s erythematic spectrum very closely. The device is paired with a mobile app that is compatible with iOS and Android. This app provides mobile push notifications as well as a powered dashboard view of UV exposure data, ensuring that the user is safeguarded from the impending dangers of melanoma and erythema.
