Multilevel Burglar Clasp

Everyone considers security to be a big concern when they are separated from their family. There is currently no viable solution to the aforementioned problem. An electrical security system that works with an Arduino UNO is described in this article. The Arduino UNO microcontroller board is part of the UBER family. It is an open-source tool that is convenient to use. Applications can be found, screened, stored, and controlled. The Arduino Mega 2560 board is used to regulate entryway access. This job demonstrates a keyless locking and opening system that uses an OTP and a pre-programmed number lock. Unauthorised access can be prevented by sending an OTP to a way of obtaining an OTP password that requires the recipient to speak with the administrator. To access it, employ a 2.8 display, which welcomes user involvement and displays all UI messages.[1] The system uses a fingerprint sensor to confirm a user's verification when they are authorised before sending a password or one-time password (OTP) through the SIM and GSM module, to the registered mobile number of the individual saved in the local SD card database. If the entered password is correct, the door will open automatically; else, On the notification given to the owner that the security was being attempted to be compromised, a message indicating the incorrect password will be TFT displayed. This hardware idea uses less electricity and three levels of security with commonly available components. In an emergency, the ADMIN can also use this system's SMS feature to unlock the door.
