Volver a DFRobot

DFRobot DFR1234 WIAnode Wireless Interactive Art Node

DFRobot DFR1234 WIAnode Wireless Interactive Art Node connects physical sensors and outputs to creative software over Wi-Fi. The DFR1234 brings touch, motion, distance, light, temperature, and button inputs into TouchDesigner and other compatible environments without requiring microcontroller programming, driver installation, or an external MQTT server. Built-in wireless communication, sensor-data handling, and standardized output help shorten the path from an interactive concept to a working installation.

The DFRobot WIAnode delivers plug-and-play I2C connections, configurable I/O, and dedicated servo outputs for linking software with physical input, lighting, and movement. A built-in OLED displays network information, while an RGB indicator communicates the connection status. Multiple nodes can operate independently on the same network, and a single node can share live data with multiple software clients for collaborative development and distributed installations.

Support for TouchDesigner, Unity, Unreal Engine, Max/MSP, vvvv, and other MQTT-compatible tools provides flexibility across interactive art, performance, education, and creative prototyping workflows. USB Type-C® power enables operation with compatible wall adapters or portable power banks, allowing flexible placement.

Features

  • Zero-code connection between physical sensors and compatible creative software
  • Built-in MQTT wireless transmission and structured JSON data
  • Dedicated TouchDesigner plugin for live sensor values and physical-output control
  • Plug-and-play auto-detection for supported I2C sensors
  • Configurable inputs and outputs for buttons, digital triggers, touch, environmental sensing, and addressable lighting
  • Dedicated servo control for adding physical movement
  • Multi-node deployment over a shared Wi-Fi network
  • Text-file network configuration without command-line tools, drivers, or pairing applications
  • Onboard display for connection and sensor information
  • RGB status feedback for network configuration and connection states
  • Simultaneous live-data access from multiple software clients
  • USB Type-C power for fixed or portable installations
  • Support for selected DFRobot Gravity modules and compatible interaction sensors

Applications

  • Interactive projection mapping: connect distance and motion sensors to trigger real-time visual changes in TouchDesigner
  • Immersive exhibitions: deploy dozens of WIAnodes across a gallery space using the multi-node MQTT network to gather visitor location data for Unity-based interactive floors
  • Kinetic art installations: utilize the 5V servo ports and I/O inputs to create responsive mechanical sculptures without writing C++ code
