Use of simple and inexpensive reflective light technology found in SpO2 monitors and pulse oximeters detects the user's hemoglobin levels, which expresses iron levels.

The incorporated SpO2 monitor works by using LED bulbs that emit frequencies of light due to peaks of light absorption by hemoglobin.

Lights will shine through the wrist and pass through the tissue onto a photosensor. This photosensor detects the wavelength of light that pass through the tissue and those that are absorbed by the blood in arteries and veins.

This information is passed to a microcontroller which correlates the wavelength.

Current continual monitoring devices require around 3 volts of energy to function

To produce this energy, we will utilize AnyLite Solar panels which are small and efficient methods to power small electronics 

The surface area of our solar panel was based off that of a solar powered calculator.
