Creating an app-controlled outdoor plant box combines gardening with modern technology, offering convenience and efficiency. Here’s a step-by-step guide to building your own smart plant box:

1. Design Your Plant Box: Choose durable, weather-resistant materials like cedar or plastic. Ensure proper drainage and space for plants to grow.

2. Integrate IoT Components: Install a microcontroller (e.g., Arduino or Raspberry Pi) to control sensors for soil moisture, temperature, and light. Connect these to a Wi-Fi or Bluetooth module for app communication.

3. Set Up Automated Systems: Add a water pump for irrigation and LED grow lights if needed. Program the microcontroller to trigger these based on sensor data.

4. Develop a Mobile App: Use platforms like MIT App Inventor or Blynk to create a user-friendly app. Link it to your microcontroller to monitor and adjust settings remotely.

5. Test and Optimize: Calibrate sensors and refine automation rules. Ensure the system conserves water and energy while keeping plants healthy.
