Design and Construction of Children's Basal Metabolic Rate Measuring Equipment Based on an Android Application For Height Parameter

Abstract

This study aims to design and develop a Basal Metabolic Rate (BMR) measurement tool based on an Android application with a focus on children, utilizing the HC-SR04 ultrasonic sensor as the main component. This device utilizes the ultrasonic sensor to measure height automatically with high accuracy. The height measurement process is carried out automatically by the ultrasonic sensor, and the resulting measurement data is then integrated with the Android application. Within the application, users can input other necessary data to calculate the child's BMR, such as age and weight. The collected data is then processed by a pre-designed algorithm to directly generate an estimation of the child's BMR. The Android application serves as a user interface that facilitates interaction and monitoring of measurement results. Testing is conducted to validate the accuracy of the device and application and to ensure the availability of accurate information for users. Thus, the results of this research are expected to provide a significant contribution to monitoring and optimizing children's health through practical and efficient BMR monitoring
