doc/hualian-sensors.xlsx the project planning document - BOMs, pricing, planning information.
doc/ the FreeMind mind-map used for planning the project. Very useful for reference.
Boards/pond-soil-proto/ the generic Catena 4410, used as a base design for the other sensor nodes. Integrated lux/temperature/pressure/humidity; external I2C, Dallas Semi OneWire, and specialized two-wire interface. In the end, all hardware was identical and based on this.
Boards/Catena-4410/Catena-4410-greenhouse/ the greenhouse sensor: integreated lux/temperature/pressure/humidity, plus external soil temperature/humidity
Boards/Catena-4410/Catena-4410-mushroom/ the mushroom-house sensor: integrated lux/temperature/pressure/humidity.
Boards/Catena-4410/Catena-4410-seaweed/ the seaweed-house sensor: integrated lux/temperature/pressure/humidity, plus external water temperature.
Boards/lib/ the library of common shapes
Boards/radio-feather-proto/ AKA the Catena 4420; this design combines an Adafruit Feather M0 BTLE with a separate Feather RadioWing to form a map-the-things node. Code is on branch MCCI-Catena of
Boards/solar-panel-0w5-usb/ the solar panel design for charging the LiPo batteries.
