Abstract

Prevention is emphasized as a preferable strategy to cure, particularly for severe diseases that frequently develop gradually. Early diagnosis of abnormal health issues can lead to successful treatments and overall well-being improvement. Vital health factors such as BMI, blood pressure, temperature, and blood glucose levels all play an important part in a person's general wellness. In this work an health testing device was developed capable of assessing these critical indicators quickly and frequently at a single stand. The study focuses on the creation of a medical measuring device capable of measuring weights up to 100kg and heights up to 7 feet. A digital weighing scale, Sonar Ultrasonic height sensor, Medium Density Fibreboard, Liquid Crystal Display, blood glucose and pressure monitoring device and Microcontroller Arduino Board are among the components utilized. A Programmable Gain Amplifier (PGA) connects the weight output from the digital weighing scale and the height measurement from the ultrasonic sensor to an Arduino microcontroller. The Arduino Uno calculates the mass-to-body ratio and reads temperature using a non-contact thermometer. On the liquid crystal display (LCD), the output results (mass, height, temperature, and BMI) are presented. The medical measuring system that was created was calibrated against a precise digital weighing system and tape rule. For weight and height, it had 99% efficiency. The device was inexpensive and had a significant positive association with the standards (weighing scale and tape rule). Other instruments, such as blood pressure and glucose monitoring devices, were connected to the system but were not incorporated into the liquid crystal display, thus their results were provided separately. The presented unified health testing equipment provides an effective and easy method for evaluating critical health fact
