Design and Development of a Cost-Effective Programmable Door Access Control System
Résumé
This research aims at the application of security
esp32 camera and smart-phone for the design of a
cost-effective programmable door access system.
The system which is comprised of ESP32-cam
which was successfully programmed with FTDI232 USB serial interface adapter in order to carry
out the desired assignment, sensor, and
electromagnetic solenoid lock is designed to be
dependent on the presence of an intruder or visitor
within the sensor range, and to send photo
notification to a smartphone for security
enhancement. Telegram application setup installed
in smartphone is used for building up WI-FI
network interface, while Unified Modeling
Language (UML) is the modeling tool applied to
model the functionality and to describe all the
activities of the system. Arduino Integrated
Development Environment (IDE) which uses
arduino code written in C++ programming
language was applied to develop the source code.
The system was later tested to ensure the
following: the output voltage was sufficient enough
to drive BC 547 transistor to saturation, TIP 122
darlington transistor was forward biased to supply
12v to the electromagnetic solenoid lock, as well as
for recognition of pictures at the appropriate
position on the smartphone, and for response to all
the peripherals and mode of operation as desired in
conformity with the software program,.The system
which was unified by integrating all the modules in
a main control loop, keeps track of those that enters
sensitive areas, and also captures the pictures of
intruders with real time feedback was tested and
implemented to restrict unauthorized entry attempt
in secured areas.
