A reed sensor is positioned near to the magnets.--> https://youtu.be/Xwc5NzPmvLA <--The clamp is glued to the wood of the rowing machine using high-quality double-sided adhesive tape. It holds well and can be removed without leaving any residue if necessary.I used some hot glue to mount the "connecting plate" to the sensor case for better holding. The easiest way to power the Raspberry is via GPIO. If you want to use a USB-C connection, you will need a right-angle plug. I sanded my angled connector flat with sandpaper until it fitted into the housing.
