Ceiling fans are commonly used in our home, office, schools and almost everywhere. It is the simplest and most inexpensive means to keep our self cool in hot and humid weather. Most commonly single phase induction motors are used for making ceiling which consumes 70W to 100W. As the energy crisis is knocking the doors, soon or the other we need to save all possible power combination of harvesting and saving can only meet highly growing energy demand. This Paper proposes a BLDC ceiling fan in place of induction based which consumes less than 30W of power and gives the similar airspeed. A Smartphone application is developed and can be used to control fan speed. This fan is implemented using permanent magnet, brushless dc motor, ARM based STM32 ARM Cortex Microcontroller, H bridge driver and Bluetooth module.
