Kalibrasi Tegangan pada Wattmeter dengan Sensor Arus Seri ACS 712 Berbasis Mikrokontroller ATM 8535

Abstract

It has been made in the power measurement tools Watt using ACS 712 series flow sensors based microcontroller Atmega 8535dan equipped with LCD display 2 x 16 characters. The purpose of this final project is to measure or to specify how large a component or load requires energy within a certain time. Based on the results of testing and calibration of measuring instruments Watt has been created, it can be reported to results which ACS712 current sensors work with a common error percentage of 3.34% compared to the value of the results of theoretical calculations, the overall system power in Watts measuring devices working properly, ie, percentage errata power measured at 3.34% and the percentage of errata power calibration results for a resistive load to the theoretical value obtained at 3.11%.
