PROTOTIPE MONITORING KETINGGIAN AIR BENDUNGAN MELALUI MEDIA SOSIAL TWITTER BERBASIS MIKROKONTROLER ATMEGA-328PU

Abstract

The prototype of this dam water level monitoring

function to provide information about the dam water level

through social media twitter and speakers. Information on

twitter social media can be found by following the twitter

account of this tool . The prototype consists of a

microcontroller Arduino Uno , HC - SR04 sensor , LCD ,

WTV020SD and the Ethernet Shield . Sensor HC - SR04 ,

read the value of the dam water level based on emission and

reflection of ultrasonic waves . Arduino Uno microcontroller

will process and display the sensor input from HC - SR04

form of dam water level on the LCD and sent via ethernet

shield to social media twitter . WTV020SD serves to ring the

speaker on the water level 10 cm , 20 cm , 30 cm and 40 cm .

The sound emitted is the normal condition of the dam , flood

alert , flood alert and flood . Water level measurement results

on LCD , manual measurement and display on twitter social

media have gotten the same results .
