將能量收集傳感器集成到Linux網(wǎng)關(guān)

　　當(dāng)EnOcean把無電池?zé)o線模塊的第一代市場，他們最獨特的特點–如20 NA喚醒定時器–必須建在復(fù)雜的離散模擬電子電路。近年來，EnOcean開發(fā)海豚芯片集成的超低功耗無線能量采集接口和微控制器。

　　這些自供電設(shè)備通過無線網(wǎng)絡(luò)連接，或者通過USB鏈路連接到中央網(wǎng)關(guān)。該網(wǎng)關(guān)可以由Linux操作系統(tǒng)提供中央?yún)f(xié)調(diào)和控制。這是建立家庭或工業(yè)自動化的自供電網(wǎng)絡(luò)的關(guān)鍵因素。

　　中醫(yī)300模塊是針對線路供電器、中繼器和網(wǎng)關(guān)和stm300設(shè)計用于能源收割機驅(qū)動的傳感器和執(zhí)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.
