PROTOTIPE PENDINGIN PERANGKAT TELEKOMUNIKASI SUMBER ARUS DC MENGGUNAKAN SMARTPHONE
ABSTRACT: The problem of
telecommunication device in BTS shelter typically hot, up and drop voltage. The
damage of telecommunication device will interrupt communication between
receiver and transmitter. This final project proposes a benefit for
telecommunication device in order to maintain the temperature of
telecommunication device appropriate with the function. This dc cooler for
telecommunication device can work automatically using Arduino Uno.This tool
utilizes work princip of a peltier element which has the side absorb heat and
removing heat and can be supplied by direct current as voltage source. The
normal temperature of telecommunication device ranged from 22oC until 26oC.
When the temperature of the telecommunication device exceeds normal temperature
then this tool will be active and when the temperature of the telecommunication
device is back to normal then this tool will be automatically off. The
temperature of the telecommunication device also can monitored by LCD and
smartphone with Bluetooth as media. DHT11 sensor in this tool can work well
with error 2,71%. The LCD can display characters letters and numbers when given
input voltage 3.9 volt and Bluetooth can connected at distance less than 15
metres without the obstacle and at distance less than 4 meters when there are
obstacle.
