FAN SPEED CONTROL USING ANDROID MOBILE

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.

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

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 systemCan be used to interface with PC, Mac or Android phones/tablets.Works with any microcontroller with Serial connectivity.

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.
