Twidec 10mm hall effect proximity sensor inductive switch npn no normally open with magnet dc5 30v njk 5002c.
This sensor is located beneath the lid of the esp32 module.
Frequently a hall sensor is combined with threshold detection so that it acts as and is called a.
Its output voltage is directly proportional to the magnetic field strength through it.
Inductive position sensors offer significant advantages over existing hall effect and other magnetic sensors.
A hall effect sensor is a device that is used to measure the magnitude of a magnetic field.

A metal rotor consisting of windows and tabs is mounted to a shaft and arranged so that during shaft rotation the windows and tabs pass through the air gap between the permanent magnet and semiconductor hall chip.
Our sensor interface ics measure linear and angular rotation movement found in a variety of automotive industrial aerospace and commercial applications.
This note provides a basic understanding of the hall effect and how allegro designs and implements hall technology in packaged semiconductor monolithic integrated circuits.
Allegro microsystems is a world leader in developing manufacturing and marketing high performance hall effect sensor integrated circuits.
The hall effect was found by edwin hall in 1879.
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 pressure position etc.
