Building an outdoor plant box with a nickel sensor is a fantastic way to combine gardening with smart technology. This DIY project not only enhances your garden's aesthetics but also helps monitor soil moisture levels for healthier plants. Here’s a step-by-step guide to get you started.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws and a drill

- Nickel-based soil moisture sensor

- Waterproof sealant

- Potting soil and plants

- Basic gardening tools

Step 1: Construct the Plant Box

Cut the wooden planks to your desired size and assemble them into a rectangular box using screws. Ensure the box is sturdy and has drainage holes at the bottom to prevent waterlogging.

Step 2: Install the Nickel Sensor

Place the nickel sensor at the center of the box, burying it slightly into the soil. Connect it to a small, waterproof display or a smart device for real-time moisture readings.

Step 3: Seal and Protect

Apply a waterproof sealant to the wood to protect it from weather damage. Let it dry completely before adding soil and plants.

Step 4: Plant and Monitor

Fill the box with potting soil and your chosen plants. Use the nickel sensor to monitor moisture levels, ensuring your plants get the right amount of water.

This smart plant box is perfect for gardeners who want to optimize plant care with minimal effort. Happy gardening!
