E-Bike Hall Sensor Throttle Now note that most e-bike throttles available today are the Hall Effect Sensor-based reliable types rather than the wear and tear potentiometer versions. At first, I also ...

That was, however, how early magnetometers worked. Today, you have lots of options, including the nearly ubiquitous Hall effect sensor.

With some hacking, he was able to attach an external Hall-effect sensor to pick up this magnet and use the signal to monitor his daily gas consumption.

The Hall-Effect sensor has a core, Hall-Effect device and signal conditioning circuitry. The current conductor passes through a magnetically permeable core that concentrates the conductor’s magnetic ...
