Re: heartbeat sensor

dont follow the IR method, it is not correct nor it gives any correct results. you can google for heart beat sensors which comes as a clip and which is fixed to find\ger tip. All other IR will never work as it is a dummy circuit., I have tried more than 30 circuits in the net and nothing works, we only assume that the reading comes.
contact some medical representatives or medical shops in hospitals and ask for heartbeat monitoring component, i got it from some representative 3 yrs back but dont have much info about it.

Yes..this is absolutely true and applies to most of the newbie members. They find similar posts at the bottom of the page and post thier querries in that thread. But usually the thread was closed without replies or Solved but nor reported years back. I have even seen 2003 threads opening now.
