What’s this then?A breathing, coughing, air-quality-sensing, Google-Sheets-logging, real-live-plant-having planter!
Using an air-quality sensor and a hidden Raspberry Pi Zero W, this little planter personifies a plant to sense indoor air quality.
Code and miscellaneous resources (laser cutter PDF and Fritzing model) are in the project’s Github repository.
Bill of MaterialsRaspberry Pi Zero W (other models should be fine, with small changes to the code and potentially wiring. The wifi is used to log to Google Sheets, but is otherwise optional.) An SGP30 air-quality sensor (we used the breakout board from Adafruit, but any similar one should work.) A 2.5W mono speaker amp and small speaker (we used this amp and this speaker) A Pimoroni Blinkt! LED strip (available here; you could also use a strip of 8 NeoPixels, with some small changes to the code) A power adapter for the Pi (perhaps this one)ProcessWe’re going to document the high-level process in this Instructable.
