🏠 Smart Home Security System

An ESP32 and Flask-based smart home security prototype that detects motion using an ultrasonic sensor and displays real-time alerts through a local web interface.

This project demonstrates the integration of embedded hardware, sensor-based detection, and a lightweight Flask web application for real-time monitoring.

🚀 Project Overview

The system uses an ESP32 microcontroller connected to an HC-SR04 ultrasonic sensor to measure distance and detect movement. Sensor readings are transmitted to a Flask-based web interface, where users can monitor the latest distance values and receive visual alerts.

⚙️ Tech Stack

• ESP32
• Arduino IDE
• C++
• HC-SR04 Ultrasonic Sensor
• Python
• Flask
• HTML / CSS / JavaScript
• SQLite

💡 Features

• Ultrasonic distance measurement using ESP32
• Motion/distance detection through HC-SR04 sensor
• Local web interface built with Flask
• Real-time sensor data updates
• Visual alert interface for monitoring
• Simple hardware-software integration prototype

🧩 System Architecture

The project consists of two main parts:

1. Arduino / ESP32 Layer Reads ultrasonic sensor data and sends measurements to the Flask server.

2. Flask Web Layer Receives distance data and displays the latest values through a local web interface.

🛠️ Getting Started

1. Clone the repository

git clone https://github.com/Busrwa/SmartHomeSecuritySystem.git
cd SmartHomeSecuritySystem

2. Run the Flask application

cd Flask_Security_System_Simple_Project
pip install flask
python main.py

The Flask interface runs locally.

3. Upload the ESP32 code

Open the Arduino project in Arduino IDE and update the Wi-Fi and Flask server placeholders:

const char* ssid = "YOUR_WIFI_SSID";
const char* password = "YOUR_WIFI_PASSWORD";
const char* flask_server_ip = "http://YOUR_FLASK_SERVER_IP:5000";

Then upload the code to the ESP32.
