Design and Deployment of an Arduino -Based Smart Home Warning System for Enhanced Safety and Security

These days, owners are in constant need of smart house warning systems to alert them to unfavorable circumstances that may arise when they are away from their residences. The purpose of this study is to describe the conception and execution of a smart home warning system based on Arduino. To facilitate communication between users and the proposed system, an Arduino Uno microcontroller has been integrated with many suitable sensors (DHT22, MQ2), actuators (buzzers and relays with an associated water valve, air fan, and light bulb), and the Internet of Things (IoT) as a wireless communication channel. The suggested method may effectively identify a wide range of undesirable occurrences, according to testing results. This technique is highly helpful in preventing resource lossesand human life caused by unwanted events.
