Abstract

This paper presents the smart fan which is operated by a small conventional motor and an ultrasonic sensor. The smart fan generates cool wind with regulated speed of wing by the distance between the user and the fan. In this research, an 8-bit microcontroller (ATmega128) and an ultrasonic sensor (NT-TS601) are utilized for the system control and sensing information. In order to obtain the speed information from the encoderless DC motor, a stroboscope is used, which provides the voltage variation by the motor speed. The proposed smart fan makes the user feel cool, convenient and safe at a low cost.
