Cloud Enabled IoT Based Alert System for Aged, Blind & Disabled Individuals

Overview

Recent advances on the Internet of Things (IoT) platform and cloud computing-based application devices continue to revolutionize our lives, from telemedicine to automated home support, by transmitting data to healthcare providers or third-party medical alert service providers using smart wearables and SOS buttons. However, no known configurable, reliable, easy to use and cost-effective alert system is available for limited mobility individuals to promptly notify their primary caregiver by the press of a button in case of an emergency or non-emergency situation. The objective of this project was to design and develop a low cost and easy to use cloud-enabled IoT based alert system that can be used by impaired individuals to notify primary and secondary caregivers via text message with 1-click while they are alone at home or without access to a phone. The solution was developed using the Wi-Fi programmable IoT button. The key cloud services used were AWS IoT 1-Click, Amazon DynamoDB and AWS Lambda functions. Once the button was pressed, an event generated in AWS Lambda caused a process in AWS Step Functions to update Amazon DynamoDB with alarm activation. Amazon PinPoint then sent text message(s) to the caregiver(s). Experimental results showed that the intended primary caregiver received notifications within 60 seconds after the button was clicked. If text was not acknowledged within 60 seconds by the primary caregiver, then the device instantly alerts the secondary caregiver. Amazon Web Services (AWS) was chosen since it provided low operational cost to reliably run infrastructure.
