Design of Arduino-Based Height and Weight Measurement System to Support Halal Healthcare Services

Abstract

Height and weight are important indicators in monitoring nutritional status and health, particularly in growing children. This study aims to design an Arduino-based height and weight measurement system utilizing the HC-SR04 ultrasonic sensor for height measurement and manual weighing. The collected data are used to calculate the Body Mass Index (BMI) and analyzed through questionnaires involving several respondents. The system is developed to support healthcare services aligned with halal principles, where nutrition and growth monitoring can be performed accurately, efficiently, and based on Islamic values. The results show that the height measurement device functions effectively and provides consistent outcomes. This system has potential applications in Islamic educational institutions, pesantren, and sharia-based healthcare services as part of efforts to preserve health by Islamic teachings.
