Automatic Door Lock System with Security using IoT

Abstract

Smart door locking systems have become more sophisticated as technology has advanced. Though an automatic password-based door lock system provides a more secure method of locking and unlocking the system, because of the ongoing Covid situation, it is extremely dangerous to touch the keypads, which are frequently used by different people. Hence, in this project we use RFID tags and Arduino. The RFID card reader detects and validates the user's access. When the card is brought close to the reader, it recognizes the radio frequency of the card and thus verifies its authenticity. key along with beeping sound, Lcd display and led blinking. We have also connected a sensor, which will be very useful during the night times for operating the door. In addition to this, face recognition technique and SMS alerting system can also be implemented in this project for enhanced security. This system is extremely valuable because to its low cost of construction, advanced capability, and simple interface. A fire alarm can be added to this system. We don't usually have fire alarms at home; therefore this device can serve as a lock and a fire alarm. Mainly, this project is designed and implemented to enhance security with ease of convenience. This system can be used in main doors, private rooms, and lockers in our home or even hotel rooms, banks, classrooms, use any other location as a secondary lock for added security.
