Using a Raspberry Pi Zero W and an\u00a0SGP30 air quality sensor from Adafruit<\/a>, 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<\/a>\u00a0for indicator lights. Finding no Python library for the I2C-accessible SGP30, they’ve written their own (which is available on Github<\/a>). 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<\/a>\u00a0and you can read how to build your own on Instructables<\/a>. A video of it in action is below:<\/p>\n
