Building an outdoor plant box with a lithium sensor is a fantastic way to combine gardening with smart technology. This project ensures your plants thrive by monitoring soil moisture levels in real time. Here’s a step-by-step guide to help you create your own smart plant box.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Lithium-powered soil moisture sensor

- Screws, nails, and a hammer

- Drill and saw

- Waterproof sealant

- Potting soil and plants

Step 1: Design the Plant Box

Sketch a simple rectangular or square design for your plant box. Ensure it’s deep enough to accommodate plant roots and the sensor.

Step 2: Cut and Assemble the Wood

Cut the wooden planks to size using a saw. Assemble the sides and bottom with screws, leaving small gaps for drainage.

Step 3: Install the Lithium Sensor

Place the lithium sensor in the center of the box, ensuring it’s buried deep enough to monitor root-level moisture. Connect it to a compatible app for real-time data.

Step 4: Seal and Protect

Apply waterproof sealant to the wood to prevent rot. Let it dry before adding soil and plants.

Step 5: Plant and Monitor

Fill the box with potting soil and your chosen plants. Use the sensor’s app to track moisture levels and adjust watering as needed.

This DIY project blends gardening with technology, making plant care effortless and efficient. Happy gardening!
