Abstract: Weight and height are used to calculate a person's Body Mass Index (BMI), which measures the amount of fat in the body. Because of this, obesity has become the world's leading public health problem. Hypertension, type-2 diabetes, renal illness, respiratory issues, degenerative joint disease, cardiovascular disease, and others are all linked to this. When designing and fabricating a locally built Arduino-based automated BMI machine with LCD display, the goal was to use Hooke's law and acoustic ultrasound waves to make it inexpensive, accurate, robust, and accessible for anyone to check their obesity status on a regular basis. The goal of this project is to automatically compute a person's body mass index (BMI) based on their weight and height and preserve that information in the system's database. For this design project, the proponents created a circuit that integrated an ultrasonic proximity sensor with an optical weight sensor, as well as software for two microcontrollers that govern and operate the whole system. Arduino, SQL Server Management Studio, Microsoft Visual Studio (NET), and Gizduino ATMEGA328 were used in conjunction with the hardware tools of an ultrasonic proximity sensor and a weight sensor (software). Proponents of the gizDuino program released the software programs to Microcontroller Units after a series of tests (MCU). After the program had been uploaded, it was connected to the hardware and tested to see whether it worked. A number of experiments were carried out, and the results show that the automated BMI calculation yields accurate results. An ultrasonic sensor and four load cells are used to measure weight, and an Arduino microcontroller is used to calculate body mass index (BMI). The design has some limitations, such as not being able to accommodate more than one person at a time and not being able to accommodate more than 250 kilograms. Sixty randomly selected students from the FEDERAL POLYTECHNIC ILE OLUJI were utilized to calculate their BMI using the equipment. To serve as a baseline, the same kids' heights and weights were measured by hand. The standard errors for height, weight, and BMI are 0.01, 0.35, and 0.12, respectively, for manual and designed automatic BMI equipment. Formation of the communication system. It not only meet the document transmission needs of local area of a business, company, school and office data, it can also perform information exchange, storage and processing, provide voice, data and image synthesis in a country or even in the worldwide. The computer communication revolution brings the important facts as follows: There is no essential difference between data processing equipment (computers) and data (switching transmission equipment). There is no essential difference.
