Simple IR remote control kit?

Hi all,

I'm designing a product which requires an IR remote control with just two functions: "on" and "off". I figured I could simply choose an IR kit (i.e. handset + receiver/decoder) from a local supplier of electronics kits, but to my amazement, I can't find any such kits. Neither Farnell nor Conrad has anything matching my specifications.

Conrad does have 2-channel 433MHz RF remote controls, but I can't use these, as product safety requires that the user must always have the product in sight when operating it. Now I could of course design a remote control circuit myself, but that would easily double my amount of work, involving programming controllers, finding a suitable handset casing with a battery compartment etcetera.

Also, the remote control kit would have to be commercially available for a few years to come at least, so I'm not looking for converted toy car controls or the likes.

Could anyone point me to a solution? Or is there perhaps a company out there, producing remote controls upon specification? And if it turns out to be "roll-your-own" after all, does anyone know of a suitable PIC-based solution (as I can only program PIC controllers at the moment)? That would at least save me the trouble of writing the software.

Thanks in advance for any suggestions, best regards,

Richard Rasker

That will not work with IR either, IR can be reflected from walls. Basicaly I can control my DVD player wheile looking the other way.

Maybe the Microchip application notes can help:

Richard, Take a look at Rainbow Kits (rainbowkits.com). They have an IR Transmitter/Receiver Kit (Model IR-5) Regards, Jon

OK, this key fob is indeed what I'm looking for, although they don't seem to offer a suitable decoder. But perhaps I'll follow up on Jan Panteltje's advice and start out with one of Microchip's application notes, building my own decoder.

Thanks for the reply, best regards,

Thanks for your reply, but I can't find this kit on their site. They do offer the IR-2 kit, but that one is a bit too simple: AFAICT, it uses a non-encoded 40kHz signal, which means that an arbitrary remote control can trigger the receiver. I think I'll have to build my own receiver/decoder after all.

Ah, yes, there's the IR-5 -- but for all I can see, it's almost identical to the IR-2, with the same flaw: it responds to any remote control used in the vicinity (it even says so in the specifications: "You can use the receiver to test TV or VCR remote controls."). For my application (a motorized piece of furniture for use in the living room), I need an IR remote control with its own, unique code.

But thanks all the same for taking the trouble to dig up the PDF :-)

Best regards,

Richard Rasker
