This post is to share a few things I have learned about hall sensor e-bike throttles but is not intended ... But for demo purposes I built a bit fancy pocket throttle tester using an Arduino Uno ...

[John Crombie] had a crack at building one using linear Hall effect sensors and magnets as the detection mechanism to good — well — effect. Using the SS49E linear Hall effect sensor in pairs ...

This sensor sits in line with the water line and contains a pinwheel sensor to measure how much water has moved through it. There is an integrated magnetic Hall-Effect sensor that ... suitable ...
