Heart Rate Receiver Module

[mlanger01]

Hi,

I'm searching for a module that I could use to receive the heart rate transmitted by regular chest belts. I found out, that the chest belts transmit the signals on 5kHz. I also found a schematic on the net and tried it and it worked.
Now I would like to use a ready designed module (sports watches are quite small and they must integrate such a module), which should be a lot smaller than the pcb I built myself.
Does anyone know where I could buy these modules?

Thanks in advance,

Matthias

Dear Mike,

thank you for your help...I've already found the schematics from Rick Moll on the internet. My actual question was: "Polar, Suunto etc have to use some kind of small module that fits into a watch. Where can I find these modules?"

Best wishes,

Matthias

Oh, sorry.

The receiver isn't a module, though. It's just a tuned circuit like any other receiver would be. You wouldn't be able to buy it, unless you bought the heart rate monitor watch and hacked it. But it's simple enough to make.

Dear Matthias,

I have brought the chest belt from Spark Technology last week. It works perfectly with my Polar HRM watch.
