Rancang Bangun Alat Pengukur Berat Badan dan Denyut Nadi Otomatis Menggunakan Sensor Loadcell dan Oximeter MAX30102 dengan Mikrokontroler ESP8266 Berbasis IoT

Abstract

I have conducted research with the title 'Design and Construction of an Automatic Body Weight and Heart Rate Measuring Instrument Using LoadCell Sensor and Oximeter Max30102 With IoT-Based Esp8266 Microcontroller”. Regular monitoring of body weight and pulse is one of the important indicators for maintaining health. Conventional measuring instruments often require manual and inefficient processes. Therefore, this study aims to design and build an automatic body weight and pulse measurement device using loadcell and MAX30102 oximeter sensors with an ESP8266 microcontroller based on IoT.This tool consists of a loadcell sensor for measuring body weight, a MAX30102 oximeter sensor for measuring pulse, an ESP8266 microcontroller as a data processor, and a Wi-Fi communication module for sending data to the IoT platform. Body weight and pulse data are processed by the ESP8266 microcontroller and displayed on an smartphone screen. This data is also sent to the IoT platform via a Wi-Fi connection for later access and analysis by users. The results of the study show that this tool is capable of measuring body weight and pulse with fairly good accuracy. This tool can also send data to the IoT platform in real time, allowing users to monitor their health regularly and easily. This tool is expected to be an effective solution for monitoring health in a more practical and efficient way.
