The EnOcean technology is an energy harvesting wireless technology used primarily in building automation systems and it is also applied to other applications in industry, transportation, logistics and smart homes.
Modules based on EnOcean technology combine micro energy converters with ultra low power electronics and enable wireless communications between batteryless wireless sensors, switches, controllers and gateways.
EnOcean protocol is now defined by the new ISO/IEC 14543-3-10 standard, which makes it the first energy harvesting wireless protocol owning its international ISO standard.
EnOcean technology is based on the energetically efficient exploitation of slight mechanical motion and other potentials from the environment, such as indoor light and temperature differences, using the principles of energy harvesting.
In order to transform such energy fluctuations into usable electrical energy, electromagnetic, solar, and thermoelectric energy converters are used.
EnOcean-based products (such as sensors and light switches) perform without batteries and are engineered to operate maintenance-free. The radio signals from these sensors and switches can be transmitted wirelessly over a distance of up to 300 meters in the open and up to 30 meters inside buildings.
EnOcean wireless data packets are relatively small, with the packet being only 14 bytes long and are transmitted at 125 kbit/s. RF energy is only transmitted for the 1's of the binary data, reducing the amount of power required.
Three packets are sent at pseudo-random intervals reducing the possibility of RF packet collisions. Modules optimized for switching applications transmit additional data packets on release of push-button switches, enabling other features such as light dimming to be implemented.
The transmission frequencies used for the devices are 902 MHz, 928.35 MHz, 868.3 MHz and 315 MHz.
