        <s:content>1 Sensor Signal Receiver&#xD;&#xA;The WS sensors send their data via radio frequency 868,35 MHz to the weather station.&#xD;&#xA;Also the ELV FS20 home automation producty use the 868,35 Mhz to communicate.&#xD;&#xA;&#xD;&#xA;The aim of this project is to gathet the information about the protocol and develop an open receiver platform.&#xD;&#xA;&#xD;&#xA;{image:img=http://knowhow.amazers.net/space/dev/projects/software/Weather+Station+ELV+WS500/Sensor+Signal+Receiver/HFE868-RX868-3V|ext=gif|align=float-right}&#xD;&#xA;I ordered a {link:HFE 868 receiver|http://www.elv.de/output/controller.aspx?cid=74&amp;detail=10&amp;detail2=12822} (ELV Partnr. 68-641-28, {link:databook as PDF|http://www.elv-downloads.de/service/manuals/RX868_3V/RX868_3V_UM_G_080527.pdf}).&#xD;&#xA;&#xD;&#xA;Actually I ordered {link:this part|http://www.elv.de/output/controller.aspx?cid=74&amp;detail=10&amp;detail2=24014} which contains the HFE 868 and was available within 2 days.&#xD;&#xA;&#xD;&#xA;&#xD;&#xA;Now I will analyse the data and protocols. After that a small open microcontroller driven circuit is to be developed to allow multi purpose usage.&#xD;&#xA;&#xD;&#xA;1.1 further information&#xD;&#xA;- {link:FS20 protocol description in german|http://www.cc2net.de/Foren/CC2Net_Forum/lesen.php?eintrag=8457}&#xD;&#xA;&#xD;&#xA;</s:content>
