Control Room Temperature Using Arduino, Sensor & Relays
Want to build a smart temperature control system using Arduino? In this tutorial, you'll learn how to automatically control room temperature using an Arduino, a temperature sensor, and two relay modules. This project can switch heating or cooling devices ON and OFF based on the room temperature, making it an excellent introduction to home automation and environmental control systems.
We'll cover the complete circuit design, wiring connections, Arduino code, relay control logic, and temperature monitoring. By using two relays, you can control both a cooling device (such as a fan) and a heating device (such as a heater) automatically according to the temperature readings from the sensor.
This project is perfect for students, electronics enthusiasts, makers, and anyone interested in Arduino automation, IoT projects, and smart home technologies.
In this video you'll learn:
✅ Temperature Sensor Interfacing
✅ Relay Module Control
✅ Arduino Automation Programming
✅ Smart Temperature Monitoring
✅ Home Automation Concepts
✅ Automatic Heating and Cooling Control
Components Used:
• Arduino Uno
• Temperature Sensor (LM35, DHT11, DHT22, or similar)
• 2-Channel Relay Module
• Breadboard
• Jumper Wires
• Fan / Heater (Optional)
Whether you're a beginner or an experienced maker, this project demonstrates real-world automation using Arduino and sensors.
