Abstract — Solar Tracking Using Beaglebone Black
Solar Tracking Using Beaglebone Black Comprehensive Technical Investigation & Design Architecture · Prepared for Research & Evaluation 1. Executive Overview & Research Problem Statement The extra 1kΩ/1kΩ divider on the output node halves the voltage range (max ~1.65 V), keeping you safely below the 1.8 V ADC hard limit.
Operational Methodology & Framework
A professional-grade dual-axis solar tracking system with real-time web dashboard, weather integration, and solar energy analytics. Tracks the sun throughout the day to maximize solar panel efficiency. Figure 1: Conceptual Model & Experimental Workflow for Solar Tracking Using Beaglebone Black 2. System Architecture & Functional Block Diagram This is a multi-sensor autonomous control system built around two microcontrollers working together: This schematic shows the core ESP32-based solar tracking circuit with LDR sensors for sun detection and MG996R servo motors for dual-axis positioning.
Experimental Findings & Validation
3. Algorithmic Processing & Methodology The web dashboard is NOT a separate website - it's embedded inside the ESP32 ! This project is released under the MIT License - see LICENSE file for details.
