RFID (Radio Frequency Identification) is an inexpensive and accessible technology. It can be used in many applications such as access control, security, asset tracking, people tracking, etc. You have seen the RFID Door Lock system in Hotels, offices, and many other places where you just have to place the card near RFID reader for a second and the door will be opened. We used an RFID reader and tag in many RFID based projects.


In our previous posts, we have built a simple RFID door lock, this time we use a real Solenoid Door Lock and control it with RFID and Arduino. Here a Hall Effect sensor and a magnet are used to detect the door movement. Hall Effect sensor will be placed on the door frame and the magnet on the door itself. When the Hall Effect sensor and magnet are close to each other, Hall Effect sensor will be in a low state and the door will remain closed, and when the sensor and magnet are not close means the door is open and hall sensor is in the high state. We will use this Hall Effect mechanism to lock and unlock the door automatically. To learn more about Hall Sensor and its working, follow the link.
