Arduino Based Safety and Security System

The availability of security and safety is considered as one of the most important and basic requirements in order to ensure the successful conduct of business and various humanitarian activities.. The idea of this research paper is to design an Arduino-based security and safety system by measuring the level of gas spread in the building, and thus the device sends signal to the mobile phone when the gas leaks more.. This system is implemented using Android and uses a gas sensor device to detect gas. When the rate of gas diffusion increases in the building, the gas sensor senses the gas and sends data to the software to show the rate of gas diffusion. If the result is more than 400 J, the red LED lights up. This will indicate the people to be alert and do the necessary actions.
