SISTEM MONITORING DAYA LISTRIK BERBASIS MIKROKONTROLER AVR ATMEGA16

Abstract

ABSTRACT: It has been made a monitoring power electricity based microcontroller AVR ATMega16 for house’s tool using. The system consisted by ACS712 censor. It able to followed the current up to 5 ampere. The voltage output from censor is followed by external filter, then went into 10 bit internal ADC by ATMega16. The value ADC is compared with the current of censor to achieve a characteristic of sensor. The result is display on LCD 16x2. It also able to do serial communication with PC that already installed with interface program automatically, continously and directly. The result shows the system have 94,65% accuracy. Keywords: Monitoring power electricity, censor ACS712, microcontroller ATMega16
