Hall Effect Limit Switch

Edwin hall for whom it is named back in the late 1870 s.

Hall effect limit switch.

It was discovered by edwin hall in 1879. I decided to pursue a limit switch based upon a hall effect sensor and the following is what i learned along the way. Mini 3 way air switch general purpose miniature rotary ii 6 position selector 300 series cartridge 400 series cartridge 4 way 4 series 45 series rugged industrial ergo low stress ltv light touch actuation general purpose. The hall effect is the production of a voltage difference the hall voltage across an electrical conductor transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.

A hall effect latch works like a switch but will stay on when the magnet is removed. Miniature hall effect switch stick. You can disconnect the hall effect switch from pin 2 of the arduino or you can just leave it alone and ignore it the sketch will only be looking at the switch on pin 3. A hall effect switch will turn on in the presence of south magnetic field on its face or north magnetic field on the opposite side.

The effect of generating a measurable voltage by using magnetic fields was discovered by dr. For clarity the original effect is sometimes called the ordinary hall effect to distinguish it from other hall effects which have. The hardware setup for this experiment is identical to the limit switch demo except you only need one hall effect switch. Although the hall effect sensor is a magnetic field sensor it can be used as the principle component in many other types of sensing devices current temperature.

Homing sensor arduino sketch. Contactless bounce free hall effect technology provides precision control and long life operation. Miniature low voltage thumb controlled 4 way hall effect switch. It will turn off when the magnet is removed.

Self centering device with no mechanical switch components to worry about degradation over time.
