Design and Implementation Data Logger with Integrated Circuit Multiplexer for Solar Panel Park

Abstract

This article describes the data logging technique for large-scale solar panels system. The input data of the developed data logger can be increased significantly by optimizing the Integrated Circuit (IC) Multiplexer analog input. Multiplexer ICs are suitable for recording parameter data on largescale solar panel systems, which are often called solar panel parks. The data logger system consists of an Arduino microcontroller equipped with a current sensor, a voltage sensor, multiplexer IC, RTC, and an SD card. The obtained data is stored on the SD-card every 5 minutes, in the form of a.txt file with the format of the day, date, time, current value, and the voltage value of each solar panel. The test results show that data acquisition on the solar panel park using a data logger with multiplexer IC has been able to store and display a large number of solar panel data.
