Ultra-low Power Management
Energy management and highly efficient energy storage are key to wireless technology for battery-less wireless sensor solutions
EnOcean modules combine micro-energy converters with ultra-low power electronics and reliable wireless communications. This enables EnOcean customers to create self-powered wireless sensor solutions that are fundamental for collecting and processing data in an intelligent system.The specific characteristics of the EnOcean protocol allow highly energy-efficient communication.
Since most energy harvesters deliver only very small amounts of power, it is necessary to accumulate it over time while the system is sleeping and to lose only a small fraction of it in the process. Therefore EnOcean sensors have an extremely low idle current. This means that only a very tiny amount of energy is consumed while the system is sleeping. The latest generation of EnOcean energy harvesting wireless sensors requires standby currents of only 100 nanoamperes (nA) or less.
The EnOcean protocol for energy harvesting wireless applications in accordance with ISO/IEC 14543-3-1X and ultra-low power specifications of IEEE 802.15.4 use only 7 bytes of protocol overhead for the transmission of 1 byte of sensor data. This protocol length is sufficient for the wireless transmission of a measured value while it needs very low power only. This meets the requirements and capabilities for wireless sensors and enables simple deployment of maintenance-free, intelligent nodes.
