IoT-based Emergency Alert System Integrated with Telegram Bot

Fires and robberies are two of the most traumatic events that can happen in a person’s life. Both situations can lead to the loss of precious objects, including jewelry, electronic gadgets, cash, and other important items that might have been acquired over the years. The impact of such events can be far-reaching and can leave an indelible mark on the victim’s life for a long time after the event. Taking safety measures to protect against fire and theft can lessen the likelihood of loss in the event of a disaster. As a result of this, it is necessary to develop an updated warning system which is an upgrade on the one that is already in existence. The Emergency Alert System (EAS) is a system that is designed to provide the user with information regarding the condition of their home. This system was built with a NodeMCU, a gas sensor, a sound sensor, and typical alert devices like an emergency light and a siren. In the past, a standard alert would only notify the people in the general neighborhood, but now it could also notify the owner even when they are not at home. This project utilized the Internet of Things (IoT) and is integrated with Telegram Bot as a tool to expand the alert system’s notification capabilities.
