Hall Effect Magnetic Pole Identifier

- Опубликовано: 2 апр 2014
- I saw a magnetic pole detector on a magnet website for $17, and that seemed pretty extreme for literally cents in parts, so I built my own, parts supplied via my own tech and consulting company, Vadien.
This device is extremely simple, and consists only of two independent circuits with a hall effect sensor (y3144), an LED, a couple resistors, and a PNP transistor. The polarity is simply defined by which direction the hall effect sensor is facing.
