Creating an outdoor plant box with a built-in air quality monitor is a fantastic way to combine gardening with smart technology. This DIY project not only enhances your garden's aesthetics but also helps you monitor environmental conditions. Here’s a step-by-step guide to get you started.

Materials Needed:

- Wooden planks (cedar or redwood for durability)

- Screws and waterproof wood glue

- Air quality monitor (such as a PM2.5 or CO2 sensor)

- Waterproof enclosure for the sensor

- Drill and saw

- Soil and plants of your choice

Step 1: Design Your Plant Box

Sketch a design for your plant box, ensuring it’s large enough to accommodate both plants and the air quality monitor. A rectangular box with dimensions around 24x12x12 inches works well.

Step 2: Cut and Assemble the Wood

Cut the wooden planks to size and assemble them using screws and waterproof glue. Leave a small compartment at one end for the air quality monitor.

Step 3: Install the Air Quality Monitor

Place the sensor inside the waterproof enclosure and secure it in the designated compartment. Ensure the sensor’s vents are exposed to the air but protected from direct rain.

Step 4: Add Soil and Plants

Fill the box with soil and plant your chosen greenery. Herbs like basil or flowers like marigolds are great options.

Step 5: Test and Enjoy

Power up the air quality monitor and test its readings. Place your plant box in a sunny spot and enjoy a smarter, greener outdoor space!

This project blends functionality with creativity, making it perfect for tech-savvy gardeners. Happy building!
