🌡️ Smart Temperature Monitor using Arduino

---

📖 Project Overview

This project was developed as part of my Embedded Systems & Internet of Things (IoT) Internship at Maincrafts Technology.

The Smart Temperature Monitor continuously measures environmental temperature using a DS18B20 Digital Temperature Sensor connected to an Arduino Uno.

Depending on the measured temperature, the system classifies it into three states:

• 🟢 SAFE
• 🟡 WARNING
• 🔴 DANGER

The LEDs indicate the current condition while a buzzer alerts the user whenever the danger threshold is reached.

The project was completely designed and tested using the Wokwi Online Simulator.
