Xcellity Technologies Launched automatic Fan and AC control using smartphone application

1. FAN SPEED CONTROL USING ANDROID
MOBILE

2. DESCRIPTION
• The project is designed to control the speed of an
induction motor such as fans, by using android
application device.
• In home automation application, convenience of
remotely controlling the speed of the fan is
achieved.
• Android Mobile or any device act as a transmitter
through Bluetooth, which is then received by
Bluetooth receiver (at the receiver end) interfaced
to a Arduino Board.

Opto Coupler
Triac

5. Arduino UNO
Arduino is an open-source
electronics platform based on
easy-to-use hardware and
software. It's intended for
anyone making interactive
projects.

6. Blutooth Module
3.3V Device with standard 5V DC
Power source.
Can also support SPI Protocol,
pins are made available.
Low power consumption, Low
cost.
Has high-performance wireless
transceiver system
Can be used to interface with PC,
Mac or Android phones/tablets.
Works with any microcontroller
with Serial connectivity.

7. Opto-couplers are made up of a LED and a light sensitive device,
all wrapped up in one package
 no electrical connection between the two devices
The light sensitive device may be a photodiode, phototransistor, or
more esoteric devices such as thyristors, triacs etc.
