Radio Technology (RF) from EnOcean for Energy Harvesting Wireless Sensor Solutions | EnOcean Technology

Patented EnOcean energy harvesting wireless sensor solution is able to generate a signal of astonishing range from an extremely small amount of energy. From just 50 μWs a standard EnOcean energy harvesting wireless module can easily transmit a signal 30 meters (in-doors). The secret lies in the signal duration - the entire process is started, executed and completed in no more than a thousandth of a second. Via gateways, EnOcean wireless solutions communicate with all major wired bus systems such as KNX, LON, DALI, BACnet or TCP/IP.

High reliability of wireless transmission

Reliable wireless transmission in systems with many sensors - the extremely short telegrams of EnOcean wireless modules enable operation of a large number of transmitters all in the same cell. Any error rate caused by telegram collisions remains extremely low. Ex-pressed in statistics, transmission reliability is still better than 99.99% for 100 wireless sensors each transmitting their data once a minute. In other words, even large office buildings or extensive industrial plants can be equipped with high numbers of EnOcean sensors, and all operating simultaneously.
