IOT BASED HEALTH CARE SYSTEM FOR THE ELDERLY
Introduction
It is a fact that elderly people forget their health check-ups to be carried out at regular intervals or
on emergency needs. This system will alert through messages personal information about their
health on mobile so they can check their historical health data any time. The best part of this
system is that it can be used by everyone and keep their health management easier than available
systems. Android application helps a person to access information anytime anywhere in the
mobile. This results in saving of time, energy and money of the user by getting early warnings of
health disorder.
The proposed device provides a solution of measurement of body parameters like ECG,
temperature, moisture, heart rate, fall detection and location of the patients. The device collects the
data from different sensors and the data is uploaded on cloud. The mobile application for the
patient and doctors contain a very simple GUI Interface for reading all the parameters in the
mobile or anywhere in the world by using internet connectivity.
We are using.various sensors and modules for performing different type of functions and the cloyd
service is used for storing all the data in cloud. It provides security and facility of accessing all the
parameters at any time which is very useful for the doctors at the time of treatment. This system
also generates an alert when required.
