IoT-Based eHealth Data Acquisition System

The aim of this paper is to present the implementation of an IoT-based eHealth system for local and remote patient monitoring. This system is based on a Raspberry Pi 3 and is capable of recording data from the following sensors: blood pressure monitor, pulse oximeter, air flow, galvanic skin response and body temperature. The graphical interface allows the user to analyze historical sensor data charts and to record new data while visualizing the live chart. This interface can be accessed either locally from the integrated Touch Display or remotely from any web-capable device. This system was built with a modular architecture in mind and a high degree of versatility. The software components for sensor access work independently, offering improved system stability in case of sensor failure.
