# 🌡️ Humidity and Temperature Monitoring System  

This project is an **Arduino-based humidity and temperature monitoring system** that uses **LED indicators** to display current conditions. The system reads values from analog sensors and provides real-time feedback through visual alerts.

## 📸 Circuit Diagram  

Here’s the circuit setup for this project:  

![Circuit Diagram](circuit_image.png)

## 🔧 Features  

✅ **Real-time monitoring** of humidity and temperature  

✅ **LED indicators** to display different humidity and temperature ranges  

✅ Easy to customize and expand for additional features  

## 🛠 Components Used  

- **Arduino Board** (Uno/Nano)  

- **Red LEDs** (5)  

- **Blue LEDs** (5)  

- **Humidity Sensor** (e.g., DHT11/DHT22)  

- **Temperature Sensor** (e.g., LM35 or similar)  

- **Resistors & jumper wires**  

## 🚀 How It Works  

1. **Connect the Circuit**: Follow the diagram above.  

2. **Upload the Code**: Load `temperature-and-soil-sensors.ino` to your Arduino.  

3. **Power On**: The system will read humidity and temperature values and display them via the LEDs.
