Building an outdoor plant box with a built-in seismograph is a creative way to combine gardening with earthquake detection. Here’s a step-by-step guide to help you create this unique project.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws and waterproof wood glue

- Seismograph sensor (available online or from electronics stores)

- Waterproof container for the sensor

- Soil and plants of your choice

- Basic tools (saw, drill, measuring tape)

Step 1: Construct the Plant Box

Cut the wooden planks to your desired size (e.g., 24"x12"x12"). Assemble the box using screws and wood glue, ensuring it’s sturdy. Drill drainage holes at the bottom.

Step 2: Install the Seismograph

Place the seismograph sensor inside a waterproof container to protect it from moisture. Secure the container at the base of the plant box, ensuring it’s level for accurate readings.

Step 3: Add Soil and Plants

Fill the box with soil and plant your favorite flowers or herbs. Leave space around the sensor container for easy access.

Step 4: Test and Monitor

Connect the seismograph to a display or app to monitor ground movements. Place the plant box in your garden or balcony where it can detect vibrations effectively.

This DIY project not only enhances your outdoor space but also adds a functional element for earthquake awareness. Happy building!
