Creating a plant-based aurora predictor using outdoor plant boxes is an innovative way to merge sustainability with technology. This DIY project leverages the natural electrical properties of plants to detect geomagnetic activity, offering a green alternative to traditional aurora detectors.

Materials Needed:

- Outdoor plant boxes (preferably wooden or recycled plastic)

- Healthy, moisture-loving plants (e.g., ferns or moss)

- Copper and zinc electrodes

- A simple voltmeter or Arduino-based sensor

- Insulated wiring

Step-by-Step Guide:

1. Prepare the Plant Box: Fill the outdoor plant box with soil and plant your chosen greenery. Ensure the plants are well-watered to maintain conductivity.

2. Insert Electrodes: Place copper and zinc electrodes into the soil, spacing them evenly. These will act as natural sensors for electrical changes caused by geomagnetic storms.

3. Connect to a Sensor: Use insulated wiring to link the electrodes to a voltmeter or Arduino setup. This will measure minor voltage fluctuations triggered by aurora activity.

4. Calibrate the System: Test the setup during known aurora events to establish baseline readings. Adjust sensitivity as needed.

5. Monitor and Predict: Regularly check the voltage readings. Sudden spikes often correlate with increased aurora visibility.

Why It Works:

Plants and soil naturally respond to environmental changes, including geomagnetic shifts. By tapping into these subtle electrical variations, your plant-based system can serve as an eco-friendly aurora predictor.

This project not only promotes sustainability but also encourages a deeper connection with nature’s wonders. Happy building!
