I'd like to incorporate a simple heartbeat sensor (ie medical sensor, that is, not a Linux-HA device) into the gumstix. Does anyone know of a source for these sensors? It seems last time one of my kids was in the emergency room they had what looked like a very simple LED on the end of the wire with a DB9M connector on the other end. Are these commonly available? I don't know what the proper term is for this other than "heart sensor" so googling just produces too much output, all of which are complete, commercial systems, not just the sensor itself. Thanks. |

Just in case anyone else ever asks about a similar device for prototyping/hobby, here are links to a 950nm LED/phototransistor in the same package for ~$1, part name TCRT1010. Output is not meant for analyzing the waveform of the heartbeat (which is what cardiologists seem to care about most), but it can give you an idea of the pulse rate, at least. http://www.vishay.com/docs/83752/83752.pdf (the photo here at Farnell's is totally crazy, but the datasheet link looks like the right item) http://export.farnell.com/jsp/endecaSearch/partDetail.jsp?sku=4606840 This part is featured in this device: http://www.emant.com/694006.page Hope this helps someone else out as well. I may still query the group for help once I get a Gumstix of my own and need help on it :) Thanks to all for the suggestions and thoughts! > I'd like to incorporate a simple heartbeat sensor (ie medical sensor, > that is, not a Linux-HA device) into the gumstix.

Try googling for the following: hearbeat sensor heartbeat sensor finger heartbeat sensor "ear-lobe" Also try the following searches: heart rate sensor heart rate sensor finger heart rate sensor earlobe That seems to be on the right track, although the closest I could find to just the sensor was this: <http://www.rtamedicalsupply.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=01&Product_Code=aPU-711&Category_Code=Monitor> Several pages I ran across seem to indicate that it's just an IR LED with a phototransistor. <http://www.emant.com/694006.page> Lots of fitness equipment seems to come with earlobe clips. Maybe you can get a replacement part through one of the fitness stores? -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Google's sensitive to the order of the words as well as the words themselves, try searching for; sensor heartbeat I've already turned up this little ditty; http://www.cosycommunications.com/earclipsensor.pdf HTH Cheers Keith On 6 Feb 2007 14:13:00 -0000, gu...@so... < gu...@so...> wrote: > > I'd like to incorporate a simple heartbeat sensor (ie medical sensor, > that is, not a Linux-HA device) into the gumstix.
