SMART IOT EMERGENCY ASSISTANCE FOR ELDERLY USING ESP32

Abstract

As the elderly population continues to grows , many individuals live alone ,increasing their risk during emergencies such as sudden illness, medical complications or other critical situations. Traditional emergency systems often require manual operation, which may be difficult for elder users in urgent moments. This project come up with the development of an Smart IoT Emergency Assistance System for the Elderly using ESP32, designed to provide a simple and efficient way for elderly individuals to call for help. The system uses a remote button that, when pressed, triggers the ESP32 to send an instant emergency alert message via Telegram to caregivers or family members. Additionally, the system integrates a DHT11 temperature sensor to monitor room temperature and display the readings on both an LCD display and the Blynk IoT application. When a high temperature is detected, the buzzer is activated and a warning message “Keep Hydrated” appears on the display. Furthermore, a push button feature is added to enhance communication feedback, when the user presses the button once, a “ Message Acknowledged” notification is sent to the Telegram bot, and when the button is held for three seconds, a “I’m Not Feeling Well” alert is sent. The proposed system aims to improve safety, enable faster response in emergencies, and provide comfort and peace of mind to both the elderly and their families by utilizing IoT technology in a practical and user-friendly way.
