An IoT-based pervasive body hydration tracker (PHT)

Urinary system disorders may be prevented by achieving a good body hydration level (BHL). This paper investigated a measurement platform set-up for detecting the shade of the (yellow) colour and its integration with the IoT principles [14] for providing ubiquitous services to the users (citizens). We propose a smart IoT-based holistic system that consists of a urine colour measurement component to be fitted in urinals. Based on RGB colour theory, the system was implemented using myRio board and interacts with a mobile application. Bio-samples (urine) gathered from volunteers were tested. A comparison of results was made by further testing the samples with a hand-held refractometer. The results showed that it is possible to infer the BHL by analysing the blue values of RGB colour and compare the results with the recommended colour chart [8]. We believe that the proposed system promotes sustainable healthy lifestyle through its ubiquitous “on-the-go” self-test solution and raise BHL awareness in a more “greener” and “personal” way.
