December 11, 2018 – At CES 2019 in Las Vegas (January 8-11, 2019), EnOcean will be launching a ceiling-mounted solar-powered occupancy sensor (PIR) for Bluetooth lighting control systems communicating via Bluetooth Low Energy (BLE). It will be a self-powered Bluetooth occupancy sensor on the market integrating EnOcean’s energy harvesting technology. The sensor, in a functional housing design, will add to EnOcean’s Easyfit portfolio of battery-free Bluetooth switches and support the company’s strategy to provide data for the digitalization of buildings using LED lighting systems as data backbone for intelligent control.
The self-powered Easyfit sensor (EMDCB) uses a passive infrared (PIR) sensor to detect motion and integrates tiny solar cells to harvest ambient light. These solar cells generate the energy for the sensor’s operation making it self-powered and maintenance-free. An energy storage element stores the harvested energy bridging a period of time when no light is available to ensure an uninterrupted operation. Besides occupancy detection, the Bluetooth sensor integrates a light sensor that allows light level control based on the actual light intensity. Like the battery-free Easyfit switches, the sensor also has a Near Field Communication (NFC) interface to be integrated and commissioned for lighting control systems via a NFC reader, a smartphone or a tablet.
In addition, the EMDCB offers security mechanisms for protected data communication. The sensor’s algorithm uses AES 128 authentication based on the device-unique random security key to generate a 32 bit signature which is transmitted as part of the radio telegram. Therefore, all transmitted radio telegrams are authenticated via AES 128 to ensure data integrity and authenticity.
With the self-powered occupancy sensor for Bluetooth systems, EnOcean will offer a complete control solution for Bluetooth lighting systems for worldwide use. Besides the battery-free Easyfit switches which allow a direct control of LED lights, the PIR sensor will enable a more complex control logic delivering data on room occupancy and light intensity via Bluetooth. This data lays the foundation for smart services such as demand-based lighting control or room occupancy management making LED lighting systems an integrated part of networked building intelligence.
In a future step, EnOcean will further expand its Easyfit portfolio of self-powered Bluetooth sensors to deliver additional building data such as temperature and humidity for more intelligent control abilities. EnOcean will be showing prototypes of this portfolio expansion at CES as well.
