A Pulse Rate-Triggered Wearable Device for Critical Assistance

Abstract

It has always been a concern in elder people that they can die during sleeping due to irregularities in the heart. Mostly, we have seen senior citizens die while sleeping and there is nothing that their families can do. Sometimes they are alone and no one is there to help them in case of emergency. To prevent this helplessness and to overcome this problem we have come up with a life-saving alarm. This device will help save many lives. It will monitor the heartbeat. The life-saving alarm will monitor the heartbeat of a person using a pulse sensor, and in case of any critical condition, it will trigger an alarm and send an emergency notification to the guardian. The device based on the Arduino microcontroller along with the associated GUI is ready and performing well according to the conditions specified. The work is aimed at saving the lives of people by monitoring their heartbeat and informing their guardians in case of a critical condition.
