EnOcean

EnOcean technology is a method of harvesting energy and is used primarily in building automation systems. Modules based on EnOcean technology rely on micro energy converters with ultra low power electronics to enable wireles communication between batteryless sensors, switches and controllers.

The EnOcean wireless standard forms part of the ISO.IEC 14543-3-10, which is optimised for wireless solutions with ultra low power consumption and energy harvesting.

EnOcean based products do not use batteries, instead they use small electromagnetic energy sources which are designed to last for at least 25 years based on more than 100 operations per day. This enables a greatly extended operational life without the need for replacing batteries.

The distance a wireless signal from an EnOcean switch to a receiver is around 300m in open space and 30m indoors. The data packet sent by the switch is relatively small and power is only used when sending the binary 1s of the control code, further reducing the power consupmtion. The information is sent three times with a psuedo random interval to remove the possibility of packets of information interfering with each other.

Example

The simplest example of an EnOcean system is a basic light switch and receiver. A receiver is installed in, or remotely from the luminaire and the switch is installed on the wall. The user operation of the switch is the same as if it were wired as a standard circuit but there are no wires to install between the switch and the receiver.
