Design and Implementation of an Internet of Things Based Smart Fan

Abstract

Thermal comfort is a pervasive necessity for occupants of the
equatorial region, and technically, it is achieved through devices like
fans and air conditioning systems. Traditional fans are not automated
which has the benefits of human convenience and management of
energy consumption. Thus, this paper proposes a smart fan with
automation functionality. The model consists of a microcontroller
(ATMega328P) that allows dynamic and faster control and a
temperature sensor that reads the room temperature. The connection
to the internet is accomplished by an ESP12F Wi-Fi module. The
developed IoT based smart fan was controlled and regulated in terms
of speed via the mobile screen interface of the application which also
displayed the temperature of the room. The user is also notified of
changes in the monitored data beyond its desired range. The device
has a battery backup to support the functionality in a power outage.
The experiment had a timely response of an average of 2.1 seconds
for 6 trials.
