Power Supply
The kit does not include batteries. You will need to prepare a 9V battery for operation. The system operates at a working voltage of 5V with a maximum output current of less than 1.5A.
Programming Environment Setup
The kit supports two programming methods: Arduino IDE (C++) and Scratch (graphical programming). Choose the method that best suits your learning needs. Online tutorials provide guidance on setting up the development environment and uploading code to the ESP32 board.

Operation
Once assembled and programmed, the Smart Farm Kit demonstrates various IoT functionalities for intelligent farm management.
Remote Control via App
The ESP32 module enables wireless communication (WiFi 2.4G, Bluetooth v4.2), allowing for remote monitoring and control of the farm via a dedicated application. The app displays real-time data such as temperature, air humidity, soil humidity, brightness, and water level.

Key Features
- Automatic Irrigation: The soil moisture sensor detects soil dryness, triggering the water pump to irrigate plants automatically. The water level sensor monitors the water reservoir.
- Farm Temperature Control: The temperature and humidity sensor monitors the environment. A fan can be activated to regulate temperature, demonstrating environmental control.
- Smart Feeding: An ultrasonic module can detect presence, and a servo motor controls a feeding mechanism, simulating automated animal feeding.
- Lighting System: A photoresistor detects ambient light levels, and an LED module can provide supplemental lighting, demonstrating light control.
- Solar Power System: A solar panel is integrated to demonstrate renewable energy concepts and potentially power certain components.
- Alarm System: A PIR motion sensor can detect movement, and a passive buzzer can sound an alarm, simulating a security system.

Troubleshooting
- Assembly Challenges: If you encounter difficulties with cable management or fitting small parts, refer to the online tutorials for detailed visual guidance. Ensure all wires are routed carefully to prevent pinching or damage.
- Fragile Screws/Parts: Exercise caution when tightening small screws. If a screw breaks or a part does not fit securely (e.g., LED for solar panel), consider using alternative fasteners or adhesives as appropriate, ensuring they do not interfere with functionality.
- ESP32 Driver Installation: For Windows 11 ARM 64 users, driver installation for the ESP32 may require specific steps. If the ESP32 is not recognized, try downloading the CH341SER driver, potentially an older version, as newer versions may not always be compatible.
- Programming Issues (Libraries/Code Upload): If you face problems with library access, placement, or code upload in Arduino IDE or Scratch, consult the online tutorials and community forums for solutions. Ensure your development environment is correctly configured.
- Web Application Functionality: If the remote control web application does not function as expected, verify your network connection, ESP32 configuration, and ensure the correct code is uploaded. Refer to the online tutorials for specific setup instructions for the web app.
