Perancangan Kwh Meter dengan Sistem Prabayar Berbasis Mikrokontroller AVR ATMega8535

Abstract

Has been designed a Kwh Meter Listrik with Prepaid System by using EEPROM Microprocessor which can maintain data though happened disconnection of energy power allowance. Device designed equiped with Keypad 4 x 4 and Microchip which will be applied as a means of payment. Data enterred through keypad will be read and lessened by Microcontroller AVR ATMega8535 according to consumer usage. LCD used as appearance display of the rest of Kwh and the rest of electric account in Rupiah (Rp). Ever greater of used energy power hence faster also deposit which we have decreasing, if microcontroller read account data = null (0), relay would be active and breaks power to payload
