Hall Effect sensors come in two basic types:
1. Threshold (alternatively called digital, or on-off), which produce a constant hall voltage when the field strength reaches a certain amplitude and/or polarity. There are many different threshold device configurations such as latching devices which turn on when a positive field strength reaches the threshold but only turn off under a negative field of the same strength, or devices which turn on when only a positive field reaches a certain threshold and are off otherwise, or devices which turn on when either a positive or negative field reaches the threshold and are off otherwise, etc. Certain devices even have programmable thresholds.
2. Linear, (analog output sensor) which produced a hall voltage proportional to the strength of the magnetic field around it. The orientation of the surrounding magnetic field determines the polarity of the voltage swing. Linear devices are more often used in musical applications, when expressive gestures must be sensed as tiny changes in position.

The simplicity of your setup and the wonderfully clear explanation is always worth the time to absorb. Best explanation of a Hall effect sensor.
Images and real life situations worth thousands of words and theories
I love this channel! You explain things clearly and give good examples of usecases. Great job!
If the magnet is meant to be directly above the plate of material at
Brilliant explanation, love the practical circuit! Thank you for posting this. I was trying to explain Hall Sensors to my 13 year old.
Your demonstrations are superb in their clarity and your explanations are so well delivered! I really appreciate all of your excellent videos! Thank you for your efforts. You are making a difference!
Thank you so much for such a concise explanation. You managed in 6 minutes what my dithering lecturer couldn't manage in over a boring hour. You are a STAR-
Best explanation of a Hall effect sensor.
Another great and useful circuit with a very well explained example. I wish more people would see the knowledge you share with the world.
LS, no doubt the informations you give in the video is highly commendable.
That was an excellent explanation! I totally get it! Please be careful when pointing to a live circuit (I know yours was off) with a pencil. The graphite center will carry current to the eraser end and can jump to the metal holding the eraser. 💢💥
So its kinda a Solid State reed switch, Cool!i've also seen "Analog" version where you can read the strength of the magnet, the stronger, the bigger the current.
Very nice ❤️❤️❤️...
thank you very much. That's video is wonderful. Right now I understand this how it works
I will try to implement that in my next class
Excellent video. Really shown in a very simple way the hall sensor principles. Thanks a lot!
Great explanation in very simple to understanding manner!
Very beautifully explained
Very informative. Thank you.
Great video, exactly what I needed to know to rebuild my fan blower a new controller. This consists of 4 coils series wounds with obviously a hall sensor for a magnetic switch 😁
