The need for Smart Building Warning Systems in high demand nowadays as they are used to warn owners about undesired situations that could happen while they are far away from their buildings. This paper aims to present the design and implementation of a Smart Building Warning System for Smart Cities. In this system, Arduino Uno microcontroller has been used with several compatible sensors (DHT22, MQ2, and PIR), 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 breaking in situations can be detected and users get notified about them via SMS messages, 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.
