ABSTRACT
In this paper, the smart door lock system using fingerprint sensor is presented. Security is a vital concern in modern society, and this study focuses on using a combination of fingerprint sensors, GSM modules, and Arduino microcontrollers to provide an effective and affordable security solution. The system stores authorized users' fingerprints in the microcontroller and uses a matching algorithm to determine whether they are allowed access. If the person is authorized, a one-time password (OTP) is sent to their registered mobile number using GSM. If an unauthorized person attempts to access the door, the buzzer sounds to alert the owner. This system can be applied in various settings, such as banks, offices, and other areas that require high levels of security. With the rise of smart buildings and the Internet of Things (IoT), security concerns are becoming even more critical. The proposed approach addresses security concerns in smart home technologies, specifically in the door lock system. This system enables the owner to monitor and control the buildings with a Smartphone-connected, Bluetooth-enabled system using an Arduino UNO microcontroller. The system can be accessed using an Android application, and if invalid login credentials are provided, the buzzer rings, and an SMS alert is sent to the owner. This approach has the potential to be implemented in other commercial sectors, such as ATMs and vending machines, using wireless communication. The work done & presented in this paper is the result of the mini-project work that has been done by the first sem engineering students of the college and as such there is little novelty in it and the references are being taken from various sources from the internet, the paper is being written by the students to test their writing skills in the starting of their engineering career and also to test the presentation skills during their mini-project presentation. The work done & presented in this paper is the report of the assignment / alternate assessment tool as a part and parcel of the academic assignment of the first year subject on nanotechnology & IoT.
