Creating a plant-based air quality monitor using outdoor plant boxes is an innovative way to blend nature with technology for sustainable living. Here’s a step-by-step guide to help you build your own eco-friendly air quality sensor.

1. Choose the Right Plants: Select air-purifying plants like spider plants, peace lilies, or snake plants, which naturally filter pollutants. Place them in sturdy outdoor plant boxes.

2. Integrate Sensors: Install low-cost air quality sensors (e.g., PM2.5, CO2, or VOC sensors) into the plant boxes. Ensure they are weatherproof for outdoor use.

3. Connect to a Microcontroller: Use an Arduino or Raspberry Pi to process sensor data. Connect the sensors to the microcontroller and program it to collect and analyze air quality metrics.

4. Power and Connectivity: Opt for solar panels to power the system sustainably. Use Wi-Fi or Bluetooth to transmit real-time data to your smartphone or a central dashboard.

5. Monitor and Maintain: Regularly check plant health and sensor functionality. Calibrate sensors as needed to ensure accurate readings.

This DIY project not only improves air quality but also promotes green technology and sustainable living. Start building your plant-based monitor today and breathe cleaner air!
