CELEC PORTAL: Smart Portal Presentation

Introduction

Smart Portal: A Comprehensive Overview of Our PCB Design

Hello everyone, my name is Kouini Samir, and I am a third-year student at USTHB. Today, I’m excited to present one of our key projects at CELEC, the Smart Portal—an advanced RFID-based door management system designed to streamline access control for our club members.

This project is a testament to the innovation, teamwork, and technical expertise that CELEC fosters among its members. As part of our ongoing efforts to develop practical solutions in electronics, the Smart Portal stands out as a sophisticated yet user-friendly system built with cutting-edge technology.

Project Overview

The Smart Portal is centered around the ESP32-S3 microcontroller and integrates several key components:

RDM 6300 125kHz RFID Reader: Facilitates secure and efficient user identification.

MOSFET-driven Door Control Mechanisms: Ensures reliable operation of the door lock, allowing only authorized access.

Power Regulation: Utilizes LM7805 and AMS1117 voltage regulators for stable operation.

ESD Protection: TVS diodes safeguard sensitive components against electrostatic discharge.

USB Debugging Capabilities: Enhances development and troubleshooting processes.

All these features come together to create a seamless access control system that is not only reliable but also easy to manage through a web-based interface.

Key Features of the Smart Portal PCB Design

Power Management

Stable and reliable power supply through voltage regulators (LM7805, AMS1117).

Essential for ensuring consistent performance of the ESP32-S3 and peripherals.

ESP32-S3 Microcontroller

Central Processing: Manages RFID data, controls door mechanisms.

Data Storage: Stores access logs, user information, and system settings.

Web Interface Integration: Allows remote management via a user-friendly website.

RFID Reader Integration

Ensures quick and accurate identification of users, enhancing security and efficiency.

Door Control via MOSFET

IRLU3114Z MOSFETs and TLP350 gate driver ensure reliable door lock operation.

ESD Protection

TVS diodes provide crucial protection against electrostatic discharge, extending the life of the system.

Overload Protection

A fuse within the power supply circuit prevents damage from excessive current flow, enhancing system safety.

Additional Functionalities

LED Debugging Control: Provides visual feedback, aiding in development and troubleshooting.

Practical Design: Strategically placed mounting holes for secure installation in various environments.

System Operation

Here’s how the Smart Portal works:

RFID Scanning: Users scan their RFID cards at the portal.

Verification: The system checks the card’s ID against the database.

Access Granted: If verified, the door unlocks, allowing entry.

Data Logging: The system logs entry times and user data for management review.

This efficient and secure system reflects our commitment to practical innovation at CELEC.

Acknowledgements: Words to PCBWay

Our Smart Portal project has greatly benefited from the support of PCBWay. The precision and reliability of the PCBs provided by PCBWay have been instrumental in bringing our design to life. Their commitment to quality and quick prototyping has enabled us to focus on developing advanced functionalities without concern for the hardware foundation.

Conclusion

The Smart Portal is more than just a project; it’s a symbol of what we at CELEC can achieve through collaboration, innovation, and a shared passion for technology. I’m proud of what we’ve accomplished and excited about the potential this system has to enhance our club’s operations and inspire future projects.

Thank you for your attention, and I look forward to any questions you might have.
