In this project, you'll build an IoT planter using the Raspberry Pi Pico RP2040 and the STEMMA Soil Sensor. Then, you'll add an AirLift breakout board to connect it to the internet and send sensor data to Adafruit IO. Finally, you'll use Adafruit IO's reactive action features to send webhook notifications about your planter to a Discord or Slack server.
For this project, you can use Slack or Discord. While it is possible to do both, this guide won't go into that.
