Arduino Body Fat Measurement
Percent body fat can be found by dividing the fat mass by the total mass and multiplying by 100.
Arduino body fat measurement. The body fat calculator can be used to estimate your total body fat based on specific measurements. Getting started with arduino. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine impedance. If you are not already familiar with the arduino ide.
It is better to connect a ww0 ohm resistor with the vcc pin of the lm35 temperature sensor. In this project we will interface a max30205 human body temperature sensor that can be easily interfaced with a fitness band or can be used for medical purposes. The basic principle behind this project is known as bioelectrical impedance analysis. The above relationship was found by lukaski et al in their paper assessment of fat free mass using bioelectrical impedance measurements of the human body.
A basic way to measure body fat percentage is by using a soft tape measure like the kind youd use for sewing to record measurements of different parts of the body. Introduction for our final project we have decided to use the microcontroller provided to make a device which would measure body fat percentage of ones body. We will use arduino nano as the main micro controller unit and also use 7 segment displays to show the sensed temperature in fahrenheit. The body fat calculator works measuring the conductivity of the body so it applies a signal an ac voltage and measures the very small for safety current.
Connect the vcc and ground pin to the 5v and ground of the arduino nano board and connect the out pin to a5 of arduino. From here to find the fat mass of the subject by subtracting y from the total mass. So in principle its simple but what i think is hard is to calibrate it because you need to have very good reference values. The basic principle behind this project is known as bioelectrical impedance analysis.
To get the best results measure to the nearest 14 inch 05 cm. For our final project we have decided to use the microcontroller provided to make a device which would measure body fat percentage of ones body.
