Electrical Data Logger of Solar Cell and Data Transmission on Internet System

Abstract

This research aims to design and create an Electrical Data Logger of Solar and Data Transmission on Internet System. In addition, data obtained from this system were compared with those obtained from standard tools.The signals was converted from analog signals to digital signals.The bit with the voltage have a linear equation of calibration as y = 0.0237x + 0.0242 with a value is R2 = 1. The bit with the current have a linear the equation of calibration as y = 0.238x + 0.2767 with a value is R2 = 1. These equations were then applied to microcontroller programming. The results of 3-days field evaluation revealed that average percentage discrepancy of voltage and current from Electrical Data Logger of Solar Cell and Data Transmission on Internet System and standard tools were 0.73% and 3.08%, respectively. Overall, it is considered that voltage and current from this tool were compatible to those obtained from standard tools.
