Using a Raspberry Pi Zero W and an SGP30 air quality sensor from Adafruit, one Instructables user, Tim Clem, has created a plant pot with personality. They’ve added a small amp and speaker for sound and a Pimoroni Blinkt for indicator lights. Finding no Python library for the I2C-accessible SGP30, they’ve written their own (which is available on Github). They’ve also added Google Sheet logging for the readings. The real magic came when they added sound effects for when the air quality dropped – they recorded a coughing sound for this which is routed through the amp and speaker. The enclosure is a mixture of wood and acrylic (which keeps the electronic components dry). All the code is available on Github and you can read how to build your own on Instructables.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
