Energy harvesting wireless sensor module 868 MHz
Manufactured By:ENOCEAN
Part Number:STM 300
The extremely power saving RF transmitter module family STM 300x of EnOcean enables the realization of wireless and maintenance free sensors and actuators such as room operating panels, motion sensors or valve actuators for heating control. Power supply is provided by an external energy harvester, e.g. a small solar cell (e.g. EnOcean ECS 3x0) or a thermal harvester. An energy storage device can be connected externally to bridge periods with no supply from the energy harvester. A voltage limiter avoids damaging of the module when the supply from the energy harvester gets too high.
The module provides a user-configurable cyclic wake up. After wake up, a radio telegram (input data, unique 32 bit sensor ID, checksum) will be transmitted in case of a change of any digital input value compared to the last transmission or in case of a significant change of measured analogue values (different input sensitivities can be selected). In case of no relevant input change, a redundant retransmission signal is sent after a user configurable number of wake-ups to announce all current values. In addition, a wake up can also be triggered externally.
