OTP BASED DOOR LOCK SYSTEM WITH MOBILE APPLICATION USING ARDUINO UNO AND ESP8266 Wi-Fi MODULE

Abstract

Home security has become one of many people's key concerns. With more time spent away from home for work, school, and other activities, residences are more vulnerable to a variety of hazards, including burglaries. Apart from risks, there are a variety of scenarios when having older adults or children with youngsters is just as crucial as locating or supervising a house. A home security system is offered in this fashion to give more safer settings. This technique promises to turn our beautiful house into a safe and more enjoyable place space where numerous activities, including surveillance, may be carried out from afar. Today, installing a home security system is a critical study in implementing cutting-edge technology to attain this purpose. One of the most useful technologies to allow remote monitoring of various household appliances is the wireless network technology. This article intends to offer a security system based on Arduino technology, in which the door lock and Wi-Fi are combined to create a fantastic powerful system along with a mobile application to send a secure password. As a result, only owners or authorized personnel can be permitted access through the door. The system operates by sending an OTP on user click and opening the attached lock if the entered code is correctly verified. In this study, we look at how to use Wi-Fi connection and OTP built into cell-phones to supplement existing door lock system issues. This system uses OTP (One-Time-Password) authentication and an Arduino smart phone-based design to create a wireless OTP door lock system that allows users to live a more convenient and secure life free of the fear of theft and other crimes.
