Welcome to the frugal-iot wiki!

Documentation is gradually being moved here from the Google Drive

High level documentation - read these first

• 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

Are you ... device user/builder, device developer, Frugal-IoT developer

Device User - for people who want to use or build something developed by others.

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.

• Programming and configuring a device on PlatformIO or ArduinoIDE

Device Developer - you want to add a sensor, or an actuator or build a custom device

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.

• Including support for a new sensor

The guide for Ardunino IDE may be useful, if you don't have access to the recommended PlatformIO.

Frugal-IoT Developer - you want to contribute to the project at a core level

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.

And Debugging

Then ... some deeper dives

• Functions high level overview
• Data flow and format
• How nodes/logger/server/broker/client find each other
• File structure for nodes
• Power design
• Power reduction
• OTA - Over The Air updates
• Configuration
• Controls

Stories, articles, updates etc.

• Google Drive: Enabling low cost sensor networks - the original white paper.
• Google Drive: First batch of prototypes
• Regular Updates: December 2024; March 2025; September 2025;
• Profiles of organizations and their needs
• Who else is doing interesting stuff relevant to Frugal IoT

OBSOLETE DOCS THAT NEED UPDATING

TO be written or ported from Google Drive - some may be obsolete

• Other parts of the architecture - server; logger; local node etc
• How & where to add your own code
• Pin usage for the D1 series
• Google Drive: Development plan for the Sensor Nodes
• Functions high level overview
