I would like to measure my heart rate and download the data to my laptop so I can do my own statistics on it.<p>I don't want something that pairs with my phone, needs me to install software or to become member of some cloud service.<p>Is there something like that?
I have not tried myself, but maybe Polar H10 strap or older H7. I didn't realize that H10 works with free app, so I bought expensive HRM too. :( The strap has internal memory that can train one session of data.<p><a href="https://nob.ro/post/polar_h10_ubuntu/" rel="nofollow">https://nob.ro/post/polar_h10_ubuntu/</a><p><a href="https://github.com/rsc-dev/loophole" rel="nofollow">https://github.com/rsc-dev/loophole</a><p><a href="https://reprage.com/post/how-to-connect-the-raspberry-pi-to-a-bluetooth-heart-rate-monitor" rel="nofollow">https://reprage.com/post/how-to-connect-the-raspberry-pi-to-...</a><p>Polar H10 is very accurate. I personally pair it with free PolarBeat app (I also have the Polar HRM) and download raw data.<p>---<p><a href="https://support.polar.com/e_manuals/Team_Pro/Polar_Team_Pro_user_manual_English/Content/Export_Data.htm" rel="nofollow">https://support.polar.com/e_manuals/Team_Pro/Polar_Team_Pro_...</a><p>>The export raw data function exports second-by-second data from a training session. Raw data export gives you a zip file with player specific folders which contain a CSV file, and a .txt file and a GPX file.<p>> The CSV file contains second by second information about heart rate, speed, distance, acceleration/deceleration and running cadence.<p>>The .txt file contains unfiltered RR interval data that can be analyzed with third party heart rate variability tools.<p>>The GPX file contains location information that can viewed in third party tools.
Your best option is a Garmin ForeRunner and the USB cable it comes with.<p>If you’re a stickler about getting the best HRM results then get one with a chest strap but the wrist-based HRM is great for most cases.
