Project Overview: Smart Door Alert System
Inspiration Behind the Project
Inspiration Behind the Project
I came up with the idea for this project after conducting research within my community, particularly based on security challenges I experienced in my previous residence. I observed that unauthorized individuals could access the building without permission, creating risks of theft and compromising residents' safety.
To address this challenge, I developed MWADOOR – Smart Door Alarm System, an IoT-based security solution designed to detect door activity and send instant alerts to users, helping improve security and prevent unauthorized access.
Project Aim: To develop an IoT-based security solution that automatically detects door activity and provides both immediate local warnings (visual/audible) and remote smartphone notifications.
What the Project Did (Core Functionality)
What the Project Did (Core Functionality)
The system bridges hardware sensing with cloud communication to provide robust, real-time security monitoring:
Automatic Detection: Uses an Infrared (IR) sensor to continuously monitor movement or activity around a doorway.
Signal Processing: An Arduino UNO acts as the central controller, receiving signals from the IR sensor and managing system outputs.
Immediate Local Alerts: Instantly triggers a local red LED (protected by a $220\Omega$ resistor) for visual warning and a buzzer for an audible alert.
Wi-Fi Connectivity: Utilizes an ESP8266 Wi-Fi module to connect the hardware setup to the internet.
Remote Smartphone Notifications: Transmits event data via Wi-Fi to the Blynk cloud application, sending real-time SMS or push alerts (such as "Alert! Door activity detected") directly to the user's smartphone.
Problem Statement and Solution
Problem Statement and Solution
The Problem: Traditional door security relies heavily on mechanical locks, manual supervision, and local alarms. These methods lack continuous monitoring, do not offer remote notifications, and require the user to be physically nearby to hear an alarm.
The Solution: An integrated, low-cost IoT architecture combining Sensing + Processing + Local Alert + Wi-Fi Communication + Smartphone Notification to ensure homeowners or office administrators are always notified of unexpected door activity.
Components Used
Components Used
Arduino UNO: Main controller that processes sensor signals.
IR (Infrared) Sensor: Detects movement or door openings.
ESP8266 Module: Provides Wi-Fi communication to bridge the hardware to the internet.
GSM Module (SIM800L/900A): Optional/alternative module capability for cellular SMS alerts.
Red LED & $220\Omega$ Resistor: Provides visual warnings while protecting the circuit against excess current.
Buzzer: Produces an audible warning sound.
Breadboard & Jumper Wires: Used for physical circuit connections.
5V Power Supply (USB Adapter): Powers the system.

NOURAH CHARITY – Community Outreach Initiative
Nourah Charity is a personal community outreach initiative dedicated to supporting vulnerable individuals, particularly people living on the streets of Kololo.
Twice a year, in April and December, I visit the streets of Kololo to distribute food and drinks to people in need. This initiative is driven by my passion for helping others, promoting kindness and making a positive difference in the community.
