Learn how to build a weight measuring system with an arduino hx711 and a load cell. To calculate body fat percentage add your waist and hip measurements and then subtract the neck measurement to determine your circumference value.
E Health Sensor Platform V2 0 For Arduino And Raspberry Pi
Arduino body fat measurement. Percent body fat can be found by dividing the fat mass by the total mass and multiplying by 100. Use the metric units tab if you are more comfortable with the international system of units si. The body fat calculator can be used to estimate your total body fat based on specific measurements. To get the best results measure to the nearest 14 inch 05 cm. 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 subjects height and weight should be entered into the code for a proper reading.
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. The basic principle behind this project is known as bioelectrical impedance analysis. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine. Learn how to build a weight measuring system with an arduino hx711 and a load cell. The basic principle behind this project is known as bioelectrical impedance analysis. Then connect dat data pin to arduino analog pin a3 and connect clk clock pin to arduino analog pin a2.
From here to find the fat mass of the subject by subtracting y from the total mass. 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. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine impedance. Skinfold measurements have been used to estimate body fat for over 50 years skinfold calipers measure the thickness of your subcutaneous fat the fat underneath the skin at certain body. 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. Connect vcc and gnd supply from arduino power source pins.
For example if your waist is 30 your hips are. 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. The arduino takes the resistance and conductance readings from the ad5933 and calculates impedance fat free mass and percent body fat.
