EnOcean Wireless Technology
No Wires. No Batteries. No Limits
EnOcean technology is based on the principle of energy harvesting. This electrically isolated, batteryless technology utilises piezoelectric generators, solar cells, thermocouples and other energy conversion techniques to energise sensors and radio switches, ensuring that no external wires are required for power or signal delivery.
With ease of installation and minimum energy usage, EnOcean technology is a cost effective and robust method to control your environment.
The battery-free wireless light switch is a good example of this technology. Using piezoelectric generators the act of depressing the switch generates enough power to transmit the requested function to a remote RF transceiver. The unit is low profile and can be easily mounted and relocated as necessary to where ever the operator requires.
