+# 🌡️ Sensor Dashboard with Raspberry Pi 4 (HTU21D)
+
+
+### 📌 Overview
+
+This project implements a real-time temperature and humidity monitoring system using a **Raspberry Pi 4** and an **HTU21D sensor**. The system collects environmental data, processes it using a C program, and displays it through a web interface accessible from any device on the network.
+
+---
+
+### 🧠 System Architecture
+
+The system follows a layered architecture where each component has a specific role:
+
+* The sensor captures physical data
+* The Raspberry Pi reads it via I2C
+* A C program processes and converts it into JSON
+* Nginx serves the data and web interface
+* The browser displays real-time information
+
+---
+
+### 🚀 What You Will Find in This Wiki
