Design and Implementation of a Customized Door Lock System for Local Needs

Abstract

This paper presents a design and implementation
of a customized door lock system utilizing Internet of Things
(IoT) technology. The proposed system focuses on accessing the
door at the ground floor from the top floor of a three- to five
story building, which is not supported by most of the prevailing
door lock systems. The idea emerged from a local survey
conducted among the 72 houses in the vicinity of Bhaktapur,
Nepal, which highlighted the local problem among the elderly
population facing difficulty in opening the door at the ground
floor while they are residing at the top floor. This research aims
to provide a low-cost, affordable door lock system to solve the
local issue of remotely accessing the door. The paper employs an
ESP32-CAM microcontroller including a camera module and a
Wi-Fi module, integrated with an RFID reader, keypad, and a
relay-controlled solenoid lock providing the mechanical
actuation for door locking and unlocking operations.
