Post by thread:Heartrate Sensor

Has anyone done any PIC work where they monitored a persons heartrate? In particular, I'm interested in being pointed in the right direction for finding a good sensor or a good method of detecting a persons heartrate. Also, some special tricks and/or lessons learned would be appreciated. Thanks in advance, Keith Weber spam_OUTkcweberTakeThisOuTinav.net

infra red through thumb beam, Small recieved intensitie variations will give the rate. Workable algorithm should be easily adaptable to other sensor methods. regards, Graham Daniel.

It had a circuit board which implemented a heartrate monitor with a serial link to a PC for display. The kit also had example PIC code for interfacing the devices. I have one somewhere, if you need me to look up the info. Reg Neale
