Sunlight Intensity Measurement System with Solar Tracking System

Abstract

Sunlight intensities are commonly measured by an acquisition device that is placed statically. At this way, we can't measure the sunlight intensity precisely all of the daylight. In this paper, using a solar tracking system with measurement device gives a precisely sunlight intensity from sunrise to sunset. With a low cost GY-302 module and an A6 GSM/GPRS module based on microcontroller Arduino Pro-Mini, the sunlight intensity measurement can be posted in a web server. The research also comparing the relationship between sunlight intensity and the solar panel generated voltage. As the results, beside the device can power itself independently by a solar panel, the posted data are plotted to be a sunlight intensity map. With this, a solar power plant development can be established in an appropriate area.
