Abstract
The need for smart home warning systems is in high demand nowadays as they are used to warn owners about undesired situations that could happen while they are far away from their homes. This paper aims to present the design and implementation of an Arduino based smart home warning system. In this system, Arduino Uno microcontroller has been used with several compatible sensors (DHT22, MQ2, and camera), actuators (buzzer and relays with attached water valve, air fan, and light bulb), and GSM as a wireless communication medium to enable the interaction between users and the proposed system. The experimental results of using the proposed system show that a variety of undesired events can be detected efficiently. Fire, gas leakage, and housebreaking situations can be detected and users get notified about them via SMS messages, emails with attached pictures, etc. Besides, some proper actions can also be performed by the proposed system including stopping fire via water and decreasing gas concentration via air ventilation. The proposed system is very useful to prevent losses in resources and human life caused by unwanted events.
