+## Description
+
+This project is a miniature smart home prototype designed to demonstrate practical home automation and safety features. It integrates an RFID-based security system for door access, alongside a climate control module that automatically adjusts windows based on real-time temperature and rain detection. For safety, it features an emergency hazard protocol that triggers an alarm and opens windows if smoke or gas is detected. Additionally, the system includes a built-in LCD screen for monitoring environmental data and a RGB lighting system, creating a complete, interactive model of modern smart living.
+
+## Motivation
+
+I chose this project because I wanted to build something highly interactive that you can see working in real life. It is fascinating to learn how data from sensors can control physical movements, like unlocking a door with a card or automatically closing the windows when it rains. I also wanted to create a system that reacts to dangers, such as turning on an alarm and opening windows if it detects smoke or gas. Building this model is a great and simple way to learn how to connect sensors, motors, and lights together.
+
+## Architecture
+
+The final system will include modules for:
+Environment sensing:
+
+- Digital temperature and humidity sensor (DHT11).
+
+- Rain sensor (detects precipitation to trigger window and awning control).
+
+- Gas and smoke sensor (MQ2) for safety monitoring.
+
+Output feedback: LCD 1602 display with an I2C interface, for showing system status (e.g., temperature, humidity, "Emergency Mode", system alerts).
+
+Motorized components: Two SG90 servo motors: one for door access, one for window control.
+
+Input system: RC522 RFID module for scanning the access card.
+
+Indicators: RGB LED module and an active buzzer (for alarms).

+## Hardware
+
+The system is built around the STM32 Nucleo-U545RE-Q microcontroller. The sensory hardware includes a DHT11 temperature and humidity sensor , a rain sensor , an MQ2 gas/smoke sensor for safety , and an RC522 RFID module for secure access. Outputs and physical movements are driven by SG90 servomotors , an active buzzer , an RGB LED module , and an I2C-enabled LCD1602 screen for displaying system data.
