Sparrows (2023)
Low cost DIY sensor network devices for installations and interactive arts.
Sparrows is a framework for creating small sensor devices that send their data over OSC, designed for use in artistic projects.
It consists of simple boxes that contain a wifi based ESP microcontroller, a 3D-printable enclosure and a sensor of sorts.
There is a SuperCollider interface available that automatically keeps track of sparrows in a network and responds to their data: sparrows-sc.
Fredrik Olofsson was a big inspiration in making these devices.
Features
- Easy WiFI setup via web interface (based on WifiManager)
- Sends data via OSC
- Configurable via OSC
- Buttons for restarting/starting access point
- 3D-printable enclosures (parametrically made using OpenSCAD)
- Easily compile firmware for different boards with different sensors using platformio environments
- Only send data when it changes, to keep network traffic minimal
- A simple handshake-procedure allows a device to register itself with a target (see SuperCollider-package for inspiration).
