IR TSOP

Post by **Merdeka** » Mon Aug 17, 2009 1:29 pm

Hey,

I've spend the weekend fooling around with a simple homebrew IR reciever. Realy simple RS232 on a breadboard (http://www.lirc.org/receivers.html). I've used a TSOP7000 because I have a Bang & Olufsen BEO4 remote lying around.

After configuring LIRC for the BEO4, I wrote a LIRC-TCP client for DomotiGa and some code so DomotiGa can send OSD-info to XBMC.
Everything works nice. I can use the BEO4 to control XBMC on my Ubuntu server and when I switch the lighting on or off I get an OSD message in XBMC.....

Nice thing about the BEO4 is that it have a dedicated light button.

So far so good..
The BEO4 uses 455KHZ and easily reaches 10 meters, so thats great. However, Being IR it won't go through a wall.

Can I just put 3 TSOP7000 in parallel?

Timo

Can always get a IR extender.

Most IR extenders work only well from 36-38khz. Not the 455khz B&O uses. IRTrans has special B&O versions of their hardware for this same reason.

didn't irtrans also have a B&O version, although that is perhaps too much for what you want.
