Could this be something? http://www.cooking-hacks.com/blog/e-health-sensor-platform-featured-in-wired Yes. It's got a pretty good fraction of the sleep study channels, and the complete thing is 450 euros. The cables appear to be too short (especially the oximeter cable). Personally I want the oxime...

Couldn't the sensor be linked to an compact Arduino with Bluetooth, eliminating cabling to the computer? That would eliminate part of the cabling. A cable between the Arduino and the sensor would still be needed, unless the Arduino with Bluetooth shield is attached directly to the probe. That might...

This probe is lower level than I'd like (I'd still need to build some hardware if I use this): http://dx.com/p/adult-soft-silicone-encryption-fingertip-oximeter-probe-blue-grey-231193#.UvbPdv2OTWw At least the connector is reasonably standard, even if the pinout is not: http://pinouts.ru/PortableDev...

I'm not asking how to make a sensor. I don't want to make a sensor either. I want to use my computer as "the computer part". In other words I want to write my own software that talks to a readily available sensor, such as one of these USB based sensors: * http://www.pulseoxstore.com/Other-Items-Acce...

I'd like to record multiple sessions of SPO2, perfusion, and pulse rate. Most of the hardware I've looked at is more complicated than I'd like, captures only a single session, and seems to require Windows software. Those nuisances aren't buying me much: I don't need a real time display. I'd therefor...
