AN ELECTRIC FAN REMOTE CONTROL UNIT USING ANDRIOD SYSTEM

The research focus on the design of an electric remote fan control (RFC) using android mobile phone. The fan automation system is divided into nine parts. 9V DC battery was used to power the Arduino board. Code was uploaded on microcontroller through the Arduino board using Arduino IDE. Proteus professional software was used to simulate the fan control circuit workability prior to soldering. A 5V, 10A DC relay was used. Trigger current for the relay was computed using Ohms law. A BC 337 transistor was used to boost the arduino current output order to trigger the relay. Limiting resistor was used to protect HC-05 bluetooth module. Multi meter was used to test against phase to neutral. Measuring tape was used to determined operational distance of the module. Locally fabricated metallic case was used to protect the designed module against mechanical damages. The existing fan without inbuilt remote facility was upgraded to use the developed RFC in this work to powered 130W fan and 100W light. Distance of operation is 15m maximum. The remote control using android phone can be used for control conveniency.
