Hi Raspberry Community,

I was wondering if we can connect a RRQ3-433 (http://www.lextronic.fr/P865-recepteur-43392-mhz-rrq3-433.html) receiver on the GPIO in oder to get values from Oregon Scientific termal sensors ?

Thanks for any advice.

I dont know about that specific IC, but if you want an easy, prebuilt solution go for a Tellstick. (http://www.telldus.com) and some software I have put togheter. http://automagically.weebly.com

But I know, part of the fun with RPi is the "built yourself" - that is what I do with the software above.

Which product in Telldus can listen to OregonScientific termal sensor?

Yes and the tellstick cost 59€, the bulk module for RF only 6€ so :)

There are also other considerations :

- use Realtime kernel (easy part)
- use a driver (make or use existing ?)
- write the app to parse the data (make or use ?)

Any feedback will be appreciated, in fact I try to create a cheaper RFXcom/Telldus device :)

First find out which channel in the 433MHz band the Oregon sensor is tranmitting on and whether it is using AM or FM modulation (or any other means). Any receiver will be best served with a proper PCB made and proper antenna.

The unit you looked at is a single channel device (433MHz band has over 20 channels).
Just another techie on the net - For GPIO boards see http:///www.facebook.com/pcservicesreading

Sure, this one is used with arduino to make an Oregon Scientific receiver, I was wondering if we can juste avoid to use the Arduino and use a transmitter to receiver/emit "things" to and from distants devices.

For example Sensors but also remote controlled lights and so on.
