data sheet ? 2010 enocean | www.enocean.com subject to modifications | march 2010 scavenger transceiver module stm 300 and stm 300c the extremely power saving rf transmitter module stm 300 of enocean enables the realization of wireless and maintenance free sensors and actuators such as room operat- ing panels, motion sensors or valve actua- tors for heating control. power supply is provided by an external energy harvester, e.g. a small solar cell or a thermal harvester. an energy storage device can be con- nected externally to bridge periods with no sup- ply 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 (every 1, 10 or 100 sec.). 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 sending or in case of a significant change of measured analogue values (different input sensi- tivities 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 be triggered externally. features ? 3 a/d converter inputs ? 4 digital inputs ? configurable wake-up and transmission cycle ? wake-up via wake pins ? voltage limiter ? threshold detector ? application notes for calculation of energy budgets and management of external energy storages product variants ? stm 300/300c: smd mountable module for use with external antenna (868/315 mhz) energy harvesting made easy with enocean wireless standard stm 300 is a bidirectional system module for maintenance-free sensor solutions based on the enocean wireless standard. using the dolphin api library it is possible to write custom firmware for the module. stm 300 / stm 300c is in-system programmable. features accessible via api: ? integrated 16mhz 8051 cpu with 32kb flash and 2kb sram ? receiver functionality ? various power down and sleep modes down to 0.2a current consumption ? up to 16 configurable i/os ? 10bit adc, 8bit dac type stm 300 stm 300c ordering code s3001-d300 s3031-d300 stm 300 stm 300c energy harvester sensors led energy storage buttons switches actuator with custom firmware
