Design and development of smart patient health monitoring system using ECG

Abstract

This paper presents the design and implementation of a compact microcontroller-based portable system used for measurement of temperature and heart pulse on real time. A long-term study of (ECG) signal during everyday activity is required to obtain a broad spectrum of heart disease categories based on heart rate changing. The typical (ECG) signal uses basic logical decisions or more complicated algorithms to process the heart disease. A patient monitoring system takes the heartbeat and body temperature by using embedded technology. This system is embedded with temperature and heart pulse sensor to monitor the health of patients. The system consists of software and hardware Bluetooth module, DSB18B20 temperature sensor and a heart pulse sensor which are directly linked to a microcontroller (ATMEGA-328PU) unit. The microcontroller, DSB18B20 and the heart pulse sensor utilized a 5V power supply, provided by a regulator called LM7805.A. 5V power supply unit activates the heart pulse sensor and the DSB18B20 connected to the microcontroller. Whenever the heart pulse and temperature is sensed by the heart pulse sensor and DSB18B20, signal is sent to the microcontroller, the microcontroller decodes and sends an instruction to the Bluetooth module which transmit data to the smart phone with the aid of a smart phone application. The response time is fast. The value of the heart pulse rate and temperature measured can also be seen on the LCD. The mobile health monitoring system was able to detect different pulse rate and body temperature of different people Back and front mobile application can be included in the design so that medical personnel can interact with the patient whenever they find it difficult to go the hospital.
