Electronic ring for monitoring vitamin D levels

A method for monitoring Vitamin D levels in a body of a user using an electronic ring, the method comprising:

• determining, using an Ultraviolet (UV) light sensor, a value of Ultraviolet B (UVB) radiation during exposure of sunlight on the body of the user;
• activating the UV light sensor when the electronic ring is worn by the user;
• calculating, using a microcontroller, an exposure time of the user to the sunlight;
• determining a UVB dosage of the user based on a reciprocal of a product of the exposure time and a predefined weightage factor, wherein the predefined weightage factor is associated with a wavelength of the UVB radiation;
• calculating an amount of Vitamin D produced in the body of the user based on the UVB dosage;
• transmitting the UVB dosage and the calculated Vitamin D level to an external user device via a wireless module;
• and
• providing visual or audible feedback through the external user device based on the transmitted data.
