DATA SHEET 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 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 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 (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 sensitivities can be selected). In case of no relevant input change a redundant retransmission signal is sent after a user configurable number of wakeups 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) Type Ordering Code STM 300 STM 300C S3001-D300 S3031-D300 © 2010 EnOcean | www.enocean.com LED Energy Harvester Energy Storage Actuator STM 300 STM 300C Sensors Buttons Switches With custom firmware 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 0.2µA current consumption Up to 16 configurable I/Os 10bit ADC, 8bit DAC Subject to modifications | March 2010 DATA SHEET EnOcean Dolphin System Architecture. Open. Flexible. Expandable. The distinguishing feature that sets Dolphin apart from other wireless system architectures is energy harvesting, which enables self-powered wireless sensors and actuators. The Dolphin system architecture joins the components necessary for an energyautonomous wireless sensor system that operates on a standardized wireless network. These include energy conversion and storage components, EnOcean wireless modules for energy management, data acquisition, data processing and wireless data transmission, and finally the software blocks operating system, API and application programs. Benefits for OEM partner Maintenance-free sensor solution with energy harvesting Simple expansion of portfolio to wireless-based products using EnOcean wireless standard Ready available and wide-ranging, interoperable As an open and expandable hardware and software architecture, Dolphin is future-oriented and fully backward compatible with EnOcean-enabled devices and system components already on the market. system product portfolio Fast implementation and time to market Low investment in R&D, T&M, etc Various evaluation tools obtainable to support development The hardware kernel of Dolphin is the EO3000I chip, a basis for simply integrated modules. EnOcean modules already have extensive firmware functionality implemented – such as basic switching, dimming and measuring – and can go straight into an application without additional programming. Its built-in application functions enable straightforward start-up and system integration.
