Hall Effect Sensors

Hall sensors, what are they, hoy they work and how to use them.

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.

Thank you for providing an alternative view, which often explains it better than most others.

Well done, you are a great help to those whom are learning.

Images and real life situations worth thousands of words and theories

If the magnet is meant to be directly above the plate of material at 0:48, I believe the Lorentz force will tend to push the electrons in the direction opposite to the one shown (electrons have a negative charge). The magnetic field lines are pointing upwards, while the motion of particles is from right to left.

In fact, this property means that both positive and negative charge carriers would be pushed towards the same side of the material even with the same direction of conventional current, allowing the first demonstration that electrons (negative) were the charge carriers.

Brilliant explanation, love the practical circuit! Thank you for posting this. I was trying to explain Hall Sensors to my 13 year old.

I love this channel! You explain things clearly and give good examples of usecases. Great job!

LS, no doubt the informations you give in the video is highly commendable.

[fltsgn]

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!

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 😁

[jlucasound]

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. 💢💥
You probably know this, I just wanted to tell everyone that may read this. Use a non conducting pointer that is all wood or plastic.
You can even make one out of a chopstick! 😃 Be safe, My Friends!

Very nice ❤️❤️❤️...
One of my favourite channel....
Thank you sir

Best explanation of a Hall effect sensor.

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.

[jdmc]

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-

[sudhirpatil]

Great explanation in very simple to understanding manner!

[hadireg]

Greatly explained mate! Thanks! what type of Hall sensor are you using in this video pls?

[TheTubejunky]

Another great and useful circuit with a very well explained example. I wish more people would see the knowledge you share with the world.

[AbdurRahman-nyne]

I will try to implement that in my next class

[alchemy]

Will that output be the same voltage value as the original value that we supplied to the hall sensor?

[fododude]

VERY interesting. I think I need to know how my flashlight that works using a magnet in the on/off switch. Light goes on/off by moving the magnet but not switching the poles.

[pbfilho]

Excellent video. Really shown in a very simple way the hall sensor principles. Thanks a lot!
