EnOcean Performance Characteristics
The radio standard “EnOcean” was developed for automation solutions in the
building technology area. Radio switches and sensors based on no-battery
EnOcean technology power themselves by harvesting ambient energy; for
example, the energy generated by pressing a switch or by sensors that exploit
light energy. With this “energy harvesting,” this radio transmitter is completely
maintenance-free and needs no cables to operate; further, the sensors can be
repositioned at any time.
The radio transmitter range can be up to 300 m in open air and about 30 m in
buildings.
In addition to the outstanding features of the EnOcean radio technology,
maintenance-free operation and versatility, EnOcean offers even more
distinguishing performance characteristics:
•
Unique for systems with numerous sensors
•
Four billion code numbers ensure clear-cut transmitter/receiver assignment.
•
Time saved by fast integration, mounting and configuration
•
Reduced fire risks
•
Cost benefits during integration, installation and operation
•
Reduced electrosmog
The ecological institute ECOLOG confirms that an EnOcean switch emits one
hundred times less HF radiation than a conventional switch (spark breakaway).
With one millionth the radiation energy of a mobile phone, the EnOcean radio
radiation is very low.
Integrated power flux density in frequency range 100 MHz to 3.0 GHz:
•
Radio switches 1.3×10
−5
W/m²
•
Conventional switches 1.5×10
−3
W/m²
In addition, having significantly fewer power cables greatly reduces low-
frequency electrosmog in the building.
