GENERAL DESCRIPTION
Basic functionality
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 en-
ergy 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 sup-
ply 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 send-
ing or in case of a significant change of measured analogue values (different input sensitivi-
ties 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 with built-in firmware
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
