Device Development and Firmware Programming for Vitamin D Management
Abstract
Lack of outdoor activities, and the use of sunscreen, low sunlight causes vitamin D deficiency. Lack of vitamin D can lead to bone disease, diabetes, muscle strength and cardiovascular disease. This study measures the amount of sunshine for each individual and establishes a management system that applies the amount of insufficient sunshine. Firmware programming is important for this operation. In this study, we improved the efficiency by using scheduling method.
