Help to build sensor for Polar FS1C watch Answered

Hello,

I got this watch Polar FS1C as a gift, unfortunately without sensor which is necessary to collect data from heart rate.
I would like to ask you, clever guys, if is it possible to (home)made cheap sensor suitable for Polar FS1C?
I could not buy this sensor in Slovakia in reasonable price so I am trying last chance here, to built it on my own.

Thank you for reply.

Mx.

No you would not be able to make the sensor yourself. It connects to the watch wireless so you would need a transmitter that matches the correct frequency. You will likely spend more money sourcing the correct parts than it would cost to buy a replacement sensor. Also your final product would end up rather large and possibly unussable.
