Building an outdoor plant box with an iron sensor is a fantastic way to combine gardening with smart technology. This DIY project ensures your plants receive the right amount of water by monitoring soil moisture levels. Here’s a step-by-step guide to help you create your own smart plant box.

Materials Needed:

- Wooden planks or a pre-made plant box

- Iron sensor (soil moisture sensor)

- Microcontroller (e.g., Arduino or Raspberry Pi)

- Waterproof sealant

- Screws and nails

- Drill and saw

- Soil and plants of your choice

Step 1: Build the Plant Box

Start by constructing or assembling your plant box. Use durable wood like cedar or redwood, and ensure it’s large enough for your plants. Seal the wood with waterproof sealant to prevent rot.

Step 2: Install the Iron Sensor

Place the iron sensor into the soil where it can accurately measure moisture levels. Connect it to the microcontroller, which will process the data and alert you when watering is needed.

Step 3: Set Up the Monitoring System

Program the microcontroller to send notifications (via email or app) when the soil is too dry. This ensures your plants stay healthy without constant manual checks.

Step 4: Plant and Maintain

Add soil and your chosen plants. Regularly check the sensor’s accuracy and adjust its placement if needed. Enjoy a thriving garden with minimal effort!

This smart plant box is perfect for busy gardeners who want to automate plant care while keeping their greenery lush and healthy.
