“In this project we’ve built IoT based smart and secure lock which have 4 layers of access. RFID + PIN + Fingerprint + OTP.
In this project we’ve built IoT based smart lock which have 4 layers of access. RFID + PIN + Fingerprint + OTP. We have slightly upgraded our previous version of the project. In this version we are going to add one more accessibility layer. That is biometric, means, we’ve added fingerprint based authentication.
- Also we are going to use different MCU development Board. In version 1 we have used Particle Photon Board, but in this project we will use ESP32 development board.
- So now, if user want to unlock this lock, then he or she should have Valid RFID, Fingerprint, PIN and OTP, means one time password.
- Also we have programmed this lock system to keep record data of user entries with user name and timestamp. This data will recorded on our dedicated mySQL database which is hosted on our webserver, hence the system Administrator can login to that web portal and, keep track of how many time this lock got opened.
- NextionTouchscreen HMI Display is used for interacting with this door lock.”
