Your Key to Wireless Energy Management Systems



PDF download

A simple solution to measure temperature in a room. The sensor uses radio frequency technology to communicate wirelessly with other EnOcean-based devices whenever it detects a change in temperature of more than 0.5K (1F). The sensor is completely self-powered by harvesting ambient solar energy so there are no wires to run or batteries to replace, reducing installation time and eliminating the need for ongoing maintenance.


Features & benefits

          Interoperable. Communicates wirelessly with other devices using the EnOcean wireless standard.

          Self-Powered. Integrated solar cell harvests indoor light to power the device and eliminates the need for wires or batteries.

          Single button with LED indicator light enables simple device configuration
