Building an outdoor plant box with a built-in carbon monoxide (CO) detector is a practical way to combine gardening with home safety. Here’s a step-by-step guide to help you create this innovative project.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws and nails

- Waterproof sealant

- Carbon monoxide detector (battery-operated)

- Drill and saw

- Measuring tape

- Sandpaper

Step 1: Design the Plant Box

Sketch a design for your plant box, ensuring it has enough space for plants and the CO detector. A rectangular box (24"x12"x12") works well for most gardens.

Step 2: Cut and Assemble the Wood

Cut the wooden planks to size using a saw. Sand the edges to prevent splinters. Assemble the box using screws and nails, leaving one side open for the detector.

Step 3: Install the CO Detector

Mount the CO detector inside the box, preferably near the top to avoid moisture damage. Ensure it’s easily accessible for battery replacement.

Step 4: Seal and Protect

Apply a waterproof sealant to the wood to protect it from weather damage. Let it dry completely before planting.

Step 5: Add Plants and Test

Fill the box with soil and your chosen plants. Test the CO detector to ensure it’s functioning correctly.

This DIY project not only enhances your garden but also adds a layer of safety to your outdoor space. Regular maintenance of the detector and plant box will ensure longevity.
