　　将能量收集传感器集成到Linux网关

　　当EnOcean把无电池无线模块的第一代市场，他们最独特的特点–如20 NA唤醒定时器–必须建在复杂的离散模拟电子电路。近年来，EnOcean开发海豚芯片集成的超低功耗无线能量采集接口和微控制器。

　　这些自供电设备通过无线网络连接，或者通过USB链路连接到中央网关。该网关可以由Linux操作系统提供中央协调和控制。这是建立家庭或工业自动化的自供电网络的关键因素。

　　中医300模块是针对线路供电器、中继器和网关和stm300设计用于能源收割机驱动的传感器和执行器。

　　The TCM transceiver modules allow line powered actuators， repeaters， and gateways to be built. The module provides several built-in operating modes for serial communication， or switching and dimming of output loads. In addition， repeater functionality （1 or 2 level） can be activated. The TCM 300 and TCM 320 offer two different mounting options. TCM 300 can be mounted as an SMD component on a host PCB while the TCM 320 is designed for vertical mounting using a pin connector.

　　The power saving RF transmitter module， the STM300 from EnOcean， enables wireless and maintenance-free sensors and actuators such as room operating panels， motion sensors or valve actuators for heating control. Power is provided by an external energy harvester such as a small solar cell or a thermal harvester that uses the Peltier effect. An energy storage device can be connected externally to bridge periods with no supply from the energy harvester. A voltage limiter avoids damaging the module when the supply from the energy harvester gets too high.
