{1007} Arduino Temperature Control System | Automatic Fan, Heater & Compressor Based on LM35 Sensor

{1007} Arduino Temperature Control System | Automatic Fan, Heater & Compressor Based on LM35 Sensor. In this video {1007}, I demonstrate a complete Arduino-based automatic *temperature controller* system using the LM35 sensor. The system intelligently activates or deactivates multiple devices — a *Heater**, **Fan**, and **Compressor* — based on temperature thresholds.

Part 1 of this video    • {684} Temperature Measurement Using LM35, ...  
You’ll learn:
✔️ How to write Arduino code for multi-range temperature conditions
✔️ How to wire up the circuit using relays or LEDs for simulation
✔️ Real-time testing and LCD temperature display
✔️ Explanation of each temperature threshold logic

📌 This video follows up on my detailed intro in EP#1046:    • {1046} Temperature Measurement Using LM35,...  

🎯 Ideal for beginners, hobbyists, and engineering students.

✅ Devices Controlled:
Heater ON below 20°C
Neutral zone between 22°C to 26°C
Fan ON above 26°C
Compressor ON above 28°C
