Project Description
Decodes Polar HRM data into XML using the SonicLink interface and a microphone. Polar SonicLink also writes rides to a CSV file that is compatible with Cyclogs.org.

Using your Polar Heart Rate Monitor with SonicLink and Windows you can conveniently download ride data into a usable format. You can then use your favourite cycling logging website and are not tied into the Polar webservice.

Currently fully decodes;

1. Polar CS200

1. Polar CS200cad

I am looking to add more HRMs to decode but don't own any other HRM models. Are you a developer with a Polar HRM?
