Abstract: This paper introduces a smart fan system crafted to enhance indoor comfort while cutting down on energy use. It employs a DHT11 sensor to track temperature and humidity, a microwave radar sensor to detect room occupancy, and a Brushless DC (BLDC) motor managed by an Arduino UNO. Features like Bluetooth for remote access and a 16×2 I2C LCD for live updates make it user-friendly. Tests reveal energy savings of 15-30% over traditional fans, thanks to its adaptive speed and presence-triggered operation. This practical, scalable design holds promise for smart homes and could evolve with AI upgrades. Keywords: Smart fan, energy saving, DHT11 sensor, microwave radar, Arduino UNO, BLDC motor, PWM, Bluetooth, occupancy sensing.
