Linear Hall-Effect Sensor According to the datasheet, SS49E is a linear hall-effect sensor that is operated by the magnetic field from a permanent magnet or an electromagnet.

A third Hall effect sensor is used to measure a throttle stick positioned on the side of the box. An Arduino micro reads the sensors and converts the analog signal to USB.

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor, an ...
