Yeah... I've taken to purchasing Atmegas 10 at a time. ;-) Honestly, part of my thinking is as I'm not commercially creating this product, no where in my goals is that it be 'user-proof'. Things like all in one package... well... I've got electronics all over the place, wired to the ceilings, walls, computers without cases... A rats nest of wires makes me smile, not cringe. Not that I like messy things, but I don't mind a little bit of extra work or complication. (This is a working computer : http://img39.imageshack.us/img39/9562/img7203v.jpg ) Different goals have different methods, I like the idea of multiple options.
I was thinking of dedicating a board just to this sensor, feeding it unregulated voltage and having a 7806 regulator just for the heater (hell, they're only $ .50) as well as a 7805 for the op-amps that are going to have to be on there. That way it doesn't interfere with onboard temp measuring. I read in one forum the sensor requires something like a break in period where it's supposed to be heated for a full day. Have you heard such a thing??
My real goal is whole area automation. I want everything monitored and coordinated. This is going to require remote sensors anyway, so there's no way around that. I'd like to create my own board for the whole thing to keep it compact, but there are too many remote sensors for me to try to avoid wires. I have personal issues with wireless communication, so that's out for me as well.
Do you mind telling me if you used the Sensair NDIR sensor in your product? That's the one I've been eyeballing... looks perfect, far as I can tell.
