Mini Project Arduino Solenoid Door Lock using RFID

RFID (Radio Frequency Identification) is a low-cost and widely available technology. It has a wide range of applications, including access control, security, asset monitoring, people tracking, and so forth. You’ve probably encountered RFID Door Lock systems at hotels, businesses, and other public venues where you simply place the card near the RFID scanner for a second and the door opens. In several RFID-based initiatives, we employed an RFID reader and tag.

We created a basic RFID door lock using an actual Solenoid Door Lock and controlling it using RFID and Arduino. To detect door movement, a Hall Effect sensor and a magnet are utilised. The Hall Effect sensor will be installed on the door frame, and the magnet will be installed on the door itself. When the Hall Effect sensor and magnet are close to each other, the Hall Effect sensor is in a low state and the door remains closed; when they are not close, the door is open and the Hall Effect sensor is in a high state. This Hall Effect system will be used to automatically lock and unlock the door. To understand more about Hall Sensor, go here.
