Project Description

Wireless signal light for displaying measuring ranges. Measuring ranges and states are clearly visible via the 3 colours red, yellow and green.

  • Local display of a measured value from a PreonCube

  • Colour representation of CO2 or humidity, for example

  • Adjustable limit range for the individual luminaires

  • Flashing signal lamps when there is no connection to a PreonCube

  • Wireless communication with a PreonCube to separate both devices locally

  • Power supply via power supply unit

Made in Germany by Virtenio


The PreonCube Signal Light (traffic light) is an optional extension to the PreonCubes. The traffic light locally displays a specific measured value in three different colored categories. The representation of the colors can deviate from the representation in the on-line range and react delayed. The traffic light can be used as an indicator when it makes sense to reduce the CO2 content in a room, for example, by ventilating and opening a window. Measuring ranges for the individual color categories can be configured.
