Design of a Heart Rate and Blood Pressure Monitoring System Using Telegram with an LM2596 Input Voltage Module

Abstract

Public health is a collective effort to improve quality of life through disease prevention and promotion of healthy lifestyles. One of the important indicators in maintaining health is blood pressure and pulse rate, as both are closely related to the risk of diseases such as hypertension. This research aims to design a sensor-based health monitoring system that can measure blood pressure using the MPX5050GP sensor and pulse rate with the MAX30100 sensor. The system is also equipped with a buzzer as a warning and a remote data transmission feature via Telegram. The method used is experimental, by comparing the sensor results against standard tools (tensimeter and oximeter) to obtain the percentage error and analyze its feasibility. Results show that the MAX30100 sensor has a low error, between 1,40% to 2,01%, with an average of 1,69% against the pulse oximeter, demonstrating its reliability for real-time pulse monitoring in non- clinical applications. The MPX5050GP sensor also demonstrated high accuracy with systolic error between 0,60% to 2,8% and diastolic between 1,51% to 2,54% against the digital tensimeter. These findings prove that both sensors are feasible to use for personal health monitoring systems. It is hoped that this system can help individuals with unstable health conditions and increase public awareness in controlling health conditions independently and sustainably.
