Pull Harder! - Student work | elective semester course

Inroduction (German)
There is no really cool monitor system for skiffs and rowing boats. We've developed one! Combining a polar heartbeat sensor with a 3D-Acceleration sensor to measure:
Heartbeat
Row beats
Max - min row beat
Race/Time
This device is splash-proof, easy to use, with an extra backlight for twilight use.


Pull Hard Device mounted between the feet.
