3. Setup and Assembly

The KEYESTUDIO Solar Tracking Kit is provided unassembled. Detailed online tutorials are available to guide you through the assembly process and code uploading. It is crucial to follow these instructions carefully. A 3.7V Lithium Ion battery is required for operation and is not included in the kit; please prepare one separately.

3.1. Online Tutorials

Access the comprehensive online tutorials for step-by-step assembly instructions and programming guides. These tutorials cover everything from basic module control to integrating all components for the solar tracking functionality.

3.2. Servo Calibration

Before final assembly, calibrate the servos as indicated in the instructions. Proper calibration ensures accurate movement of the solar panel for optimal tracking.

3.3. Wiring and Connections

Carefully connect all modules and sensors to the Keyestudio UNO Development Board using the provided DuPont wires. Pay close attention to the polarity and pin assignments specified in the online guide to prevent damage to components.

4. Operating Instructions

4.1. Solar Tracking Functionality

The kit is designed to automatically track the sun's position. The 4 ambient light sensors detect the light intensity, and the 2 DOF servos adjust the solar panel's angle (180°+180° range) to maximize light exposure. This ensures efficient conversion of light energy.

Figure 4: The solar panel automatically adjusts its position to follow the light source.

4.2. Smartphone Charging

The kit includes a smartphone charging module. Once the internal battery is sufficiently charged by the solar panel, you can connect your smartphone to the charging module to power it. The charging module outputs 5V/1A. Note that this module may not support iOS systems.

Figure 5: The solar panel charges an internal battery, which then powers the smartphone charging module.

4.3. Reading Sensor Data

The LCD1602 display shows real-time data from the integrated sensors. This includes light intensity (lux) from the BH1750 sensor, temperature, and humidity from the DHT11 sensor. This allows for monitoring environmental conditions.

4.4. Manual Control

A push button module is included, allowing for manual interaction or control over certain functions as programmed. This can be used to override automatic tracking or trigger specific actions.

5. Maintenance

• Cleaning: Keep the solar panel and sensors clean from dust and debris to ensure optimal performance. Use a soft, dry cloth for cleaning.
• Storage: When not in use, store the kit in a dry, cool place away from direct sunlight and extreme temperatures.
• Battery Care: If using a rechargeable battery, follow the manufacturer's guidelines for charging and discharging to prolong its lifespan. Remove the battery if the kit will not be used for an extended period.
• Component Inspection: Periodically check all connections and components for any signs of wear or damage. Ensure all screws are tightened.
