Detected movement and the measured illumination level are communicated wirelessly using EnOcean advertising telegrams according to the EnOcean sensor specification.
EMDC operates self-powered in most applications based on available light in the environment (electric or natural light). It therefore can be flexibly mounted on the ceiling without the need for any wiring.
Key parameters of EMDC can be configured using the integrated NFC interface. Additionally, a simple user interface consisting of one button and one LED allows for simple configuration without additional tools.
