Nowadays, there is a need to secure many important places such as gas stations, power stations, hospitals, banks, schools or even our homes. From this standpoint, the goal of this project is to use modern technology such as smart technology and the Internet of things to secure important places. The project works to secure the entrance, the gate and the garage. In addition to the road safety system is used. In this system, when the speed of a car exceeds a certain limit, a ground mechanism open and stop this car. Also, the project includes a fire and gas leakage insurance system, a ventilation and heat control system, and another system for controlling soil irrigation. All of the above is executed with the help of smart devices such as security alarms, sensors, etc. and are coordinated by Arduino microcontroller. The place is monitored and controlled remotely via an application on the mobile device using Internet of Things technology where a wireless IP camera is used. In addition, a solar power source is used as a backup system.
