IOT Integration in Two-Axis Sun Tracking System with LDR Sensors in a Wheatstone Bridge Circuit

In recent years, solar energy has gained significant attention as a clean and sustainable source of power. To maximize the efficiency panels, it is crucial to track movement sun ensure optimal exposure sunlight throughout day. this project, propose two-axis tracking system that utilizes Light Dependent Resistors (LDR) sensors employs Wheatstone Bridge Circuit for accurate position detection. Additionally, integrates Internet Things (IoT) technology enable remote monitoring power generation process. The consists two main components: sensor module control module. LDR strategically placed detect intensity sunlight. employed measure resistance changes in accurately determine sun's relative panels. processes data generates signals adjust direction panels accordingly. Furthermore, incorporates IoT real-time monitoring. collected data, including generated voltage panel direction, are transmitted cloud platform via wireless communication protocols such Wi-Fi or cellular networks. Moreover, integration facilitates monitoring, enabling users optimize production identify any potential issues promptly. Keywords—Wheatstone bridge, sensors, DAST system, PV panel, closed-loop Things.
