Portable Real-Time BMI Nutritional Advice

Abstract

Overweight and obesity refer to body weight that is greater than what is considered normal or healthy for a certain height. Your body mass index (BMI) is one way to tell if you are at a healthy weight, overweight, or obese. The BMI is a measure based on your weight in relation to your height. Existing device only measure weight and height require the user to self-calculate their BMI based on the formula related to their weight and height. Furthermore, currently available systems cannot keep track user’s previous BMI record and do not provide a guidance or nutritional advice based on user’s current BMI. The solution to this is a proposed project which is an IOT based Portable Real-Time BMI nutritional advice that able to calculate user’s BMI and keep current and previous user’s record. The project aims to help people to monitor their BMI as a way of keeping a healthy weight. The objectives of this project are to develop a portable real-time measuring system to measure height and weight that can auto-calculate BMI and give nutritional advice using web-based application. The sensors used in this system are HX711 Load cell amplifier and Ultrasonic sensor. The system will perform weight and height measurement upon user’s command. Data from both sensors will be sent to NodeMCU Wi-Fi module for BMI calculation. Virtual server is used to store the data from the system app. Apart from BMI calculation, this system is able to display user’s previous BMI data as a performance tracker in monitoring their BMI. The application is also able to generate a nutritional advice based on user’s current BMI.
