Dream A Garden

Another IOT Garden. Built on a Raspberry Pi. Powered by Dark Sky.

Getting Started

Run the following from the repository root directory to install the needed dependencies.

# The minimum dependencies needed to run weatherBot
pip3 install -r requirements.txt
# Additional dependencies needed for testing, linting, and validating
pip3 install -r requirements-dev.txt

Dependencies

• darkskylib - a python library for the Dark Sky API.

• Adafruit IO - a python library for the Adafruit IO API. See the documentation for more information.

• Adafruit Seesaw

I/O Components

• Adafruit Soil Sensor
  • Moisture reading ranges from about 200 (very dry) to 2000 (very wet).
  • Ambient temperature from the internal temperature sensor on the microcontroller is not high precision, maybe good to + or - 2 degrees Celsius.

Sensor Routing

GPIO #	Pi I/O	sensor I/O	JST PH Color
