A sensor cover for the Adafruit Stemma Soil Sensor:

Snaps Together nicely no glue needed. I print in PETg for outdoor durability.
Logo on top (for those of you wondering) is for Team 4160 for which I am a mentor.
This is a part that is useful to create a home garden sensor that logs and graphs data.
Really Cool Live data from mine:

This soil sensor together with an RPI 2040 aka Pico, Airlift Board, a DHT 22, and the Adafruit IO site to graph and see live temperature and sensor data:
See Live data from my Garden (I have 2 Soil sensors attached with this code https://github.com/mperino/GardenSensor/blob/main/Pico_Garden_Home.py ).
Steps to setup your sensor:
You will need to create an Adafruit IO account, to log the data. Create feeds (temp, humidity, soil). Setup your board to run CircuitPython with the required libraries(adafruit_dht, busio, digitalio, adafruit_esp32, seesaw). Put the Pico_Garden.py code on the board, and the secrets.py. Then edit the secrets.py file to setup your WiFi and Adafruit account.
