Abstract :
The emerging technological trend in the healthcare sector is geared towards changing the usual healthcare services and routine medical check-ups from hospital centric to home centric. This offers a reduction in the total expenses spent and reduces the workload on the clinical personnel. As such, remote health monitoring systems based on Internet of Things (IoT) are developed to aid in monitoring some physiological parameters (such as: heart rate, body temperature, blood pressure, glucose level, etc.) of patients at home. The devices often use internet connectivity to effectively monitor the health condition of patients. They are mostly developed using Arduino microcontrollers and sensors. The devices often use IoT platforms such as ThingSpeak for gathering, visualizing, and analyzing the sensed data. In this paper, the significance of developing remote health monitoring systems is discussed. Several literatures using diverse measuring parameters and different approaches were reviewed. The factors necessitating the need for such systems, the objectives for designing the systems, potential for product commercialization, application area in the health sector, and system requirements are discussed.
