IoT Based Smart and Secured Mobile Charging Station in Public Place

In this era of technological advancements, mobile phones became a part of people's daily activities. Many countries have charging port facilities in public places, but they are at high risk of security. Many developing countries don't have a sufficient charging port in public places. A smart and secured mobile phone charging station is proposed in this paper. The system can be easily installed anywhere and designed so that this system can charge any mobile phone. Arduino is the core component of this system. A coin recognition module is used to recognize a valid coin that has been entered; then, the system proceeds further action. According to the amount of coin, the system set the particular time of charging the mobile phone. To ensure the system's security, we have used a solenoid door locker protected by RFID cards; only by using this, the user will be able to open the door and access the device. There is also some feature that helps the system provider to collect the coin from the system before it is overloaded. All the features have been tested properly by building a prototype.
