Documentation is gradually being moved here from the Google Drive
- A theory of change
-
Systems Architecture
- Including pointers to the github repos for each component.
- Nodes - how the sensor nodes work and the different parts of their design.
- Supported Hardware - understand what is currently supported.
- High level view of simple scenarios
- Updates - all the News as it happens.
- Collaborating
See How To for how to flash a specific project e.g.: Air Quality Sensor; Temperature and Humidity Sensor; Weight sensor / Scales; Agriculture sensor or an off-the-shelf device like a Sonoff.
See How To for how to get setup as a developer, or work on different parts of the system - for example to add a new sensor.
The guide for Ardunino IDE may be useful, if you don't have access to the recommended PlatformIO.
