I guess I would never buy a PIR sensor for $50. You can get them for $6, so that's what I anchor off of. Not that I'd expect your product to be close to $6, but $50 PIR sensors are way overpriced, so I wouldn't ever think to compare to those.

Despite heavily automating my own home and being the person who sets everything up for my extended family, it seems I'm probably not your target market. Sounds like you have some cool tech though!
