This post is to share a few things I have learned about hall sensor e ... tester is based on Arduino Uno, you can use other similar boards like Arduino Nano, Pro Mini, etc. to make it more compact.

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 ...

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 ...

A pair of Hall effect sensors are mounted in the ... measure the angles of the pantograph’s joints. The Hall sensors are read by an Arduino Nano, which computes the angles into movement of ...
