IoT Cloud System Based Dual Axis Solar Tracker Using Arduino

Abstract

Because of the urgent need for electricity and the shortage of it, humanity has searched for the most environmentally friendly and well-available types of energy. From the different types of energy that comes from the sun, wind, tides, hydro and thermal energy that emanates from the earth and is spontaneously replenished naturally, the focus has been on solar energy. Which represents the best source of energy as it is naturally available in life and does not cause any damage or pollution in particular to nature and life. Not to mention after-math effects. This project led to the development of a two-axis solar tracker with the Internet of Things (IoT) or cloud platform. The solar system improves the performance of the solar panels due to following and the sun's mobility. Four light-dependent resistors (LDRs) were used to detect sunlight and the maximum intensity of the light, two servo motors have been utilized to rotate the panels based on sunlight detection by the LDR, after that, we use the WiFi as an intermediary between the Arduino device and the cloud platform. The cloud represents the final destination for the data to be stored, manipulated and processed.
