Building an outdoor plant box with a chlorine sensor is a fantastic way to ensure your plants thrive by monitoring water quality. Here’s a step-by-step guide to help you create this practical garden feature.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws and waterproof wood glue

- Drill and saw

- Waterproof sealant

- Chlorine sensor kit (with digital display)

- Waterproof container for sensor housing

- Soil and plants of your choice

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 the corners are square. Apply a waterproof sealant to protect the wood from moisture.

Step 2: Install the Chlorine Sensor

Drill a small hole near the base of the box to thread the sensor wires. Place the chlorine sensor in a waterproof container to shield it from soil and water. Connect the sensor to a digital display for easy readings.

Step 3: Add Soil and Plants

Fill the box with high-quality soil and plant your chosen greenery. Water the plants and check the chlorine sensor’s readings to ensure optimal water conditions.

Maintenance Tips:

- Regularly calibrate the sensor for accuracy.

- Check for wood rot or sensor damage periodically.

- Adjust watering based on chlorine levels to prevent plant stress.

This DIY project combines gardening with smart technology, helping you maintain a healthier outdoor space. Happy building!
