Diseño e implementación de un equipo basado en microcontroladores y energía solar para determinar el índice de masa corporal en humanos.

Abstract

The present project of investigation is oriented to the obtaining human anthropometric indicators for the nutritional diagnosis of an individual, for it, a system was developed, based on microcontrollers and sensors, which are able to measure in a correct and precise form, values like weight and height of a person, for later calculate the body mass index and body fat, and finally show it on an LCD, besides the project will use photovoltaic energy for its power, so it wouldn't need to be connected to the public network, for the development of the project was necessary to design a physical support where all the subsystems of the equipment would be housed, and the correct functioning of the equipment would be achieved. Experimental and bibliographical methodologies were used, which allowed the analysis of different scientific articles related to the proposed topic and also to the compression of the characteristics of the elements to be used. At the end of the development of the equipment, the correct functioning of the equipment is evidenced, which has a percentage of error of measurements of weight and height of less than 2%, fulfilling the proposed hypothesis. The project aims to raise awareness among people about the issue of obesity. The values of body mass index and body fat were made with people of different weights, statures, sexes and ages with an error lower than 2%, so that it is possible to develop medium precision equipment based on low cost sensors for the determination of anthropomorphic values.
