Smart Ceiling Fan Speed Optimizer Kit: Build an Energy-Efficient Fan with Arduino Uno

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a ceiling fan that senses when you enter a room and automatically adjusts its speed to the perfect level based on the current temperature—no manual switches, no wasted energy. With this Arduino-based Smart Ceiling Fan Speed Optimizer Kit, you'll build a fully functional home automation system that reads ambient temperature via a DS18B20 probe, detects occupancy with a PIR sensor, and controls fan speed through a TRIAC dimmer circuit. Perfect for tackling real-world energy management challenges in Indian homes or as an advanced B.Tech project.

What You'll Build

You'll assemble and program a ceiling fan speed controller that intelligently modulates speed using pulse-width modulation (PWM) through a BT136 TRIAC and MOC3021 optocoupler. The system continuously monitors the DS3231 real-time clock to log usage patterns and displays current temperature and fan status on a 0.96-inch OLED screen. By the end, you'll have a prototype that demonstrates how home appliances can adapt to human presence and environmental conditions, reducing electricity bills without sacrificing comfort.

What You'll Learn

• Interfacing a DS18B20 digital temperature sensor with Arduino for accurate room temperature readings
• Implementing occupancy detection using an HC-SR501 PIR sensor to trigger fan operation
• Controlling AC fan speed safely with a BT136 TRIAC and MOC3021 optocoupler for zero-crossing-based dimming
• Integrating a DS3231 RTC and 0.96-inch OLED to build a time-aware, display-equipped system

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This advanced kit is designed for engineering students (B.Tech ECE/EEE final year), participants in the Smart India Hackathon, and hobbyists with a solid grasp of Arduino programming. If you're working on a home automation capstone project at IIT, NIT, VIT, or BITS Pilani, or building a prototype for ATL Tinkering Lab's senior challenges, this kit gives you a pre-validated system so you spend less time debugging and more time innovating.
