ABSTRACT
The automatic fan control by using temperature censor based on
Arduino is created to help the user who is still using the manual
mechanism. The problem which is often faced from the switch
installation to the electricity power source and the fan’s speed button
and direction controlling. This can be designed by using Arduino
Uno microcontroller technology and Wifi Shield to access the data
exchange. In this case, the Android smartphone is able to monitor
the movement and the fan’s on-off condition. The temperature which
is in the room can be known from the LM35 Censor reading. The fan
movement whether vertical or horizontal will be moved by Servo
Motor. The fan movement scheme which will be set by Relay. Based
on the testing result by using User Datagram Protocol (UDP), the
system can be accessed more than one Android smartphone device.
The accuracy percentation of the LM35 Censor is 71.6 % and the
system access scope on the enclosed space is 5 meters.
