Your explanation has served the purpose very well. It was great. I feel sorry for those who commented negatively. They will never appreciate any good work.
Thanks Dan! I was a Master Mechanic for a Caterpillar dealer for 25 years, Now I am a technical trainer and I teach electrical as well as all other systems on Heavy Equipment. Your drawings seem to make a real impact on the ability to grasp the concept of whatever switch, sensor or Sender, we may be covering at the time. I also use and promote the Loadpro leads in my classes as I have found them to work exactly as advertised and make troubleshooting high resistance in circuits much simpler. Keep posting the great videos!

Thanks Dan, still having a positive impact after 3 years! Also, I have learned to reinforce a learning concept, good for students, make drawings of the details of function or theory and inject a little fun, a picture remembered is worth its weight in gold.
Well heck - you're welcome. Glad to do it, glad to know it helps, and glad to know you're better off for it. Feel free to email with questions. Stay safe.
I am now fully edumaverified in the dark art of Hall effect sensors. Never seen electrons drawn as zoomin' groovy little guys, almost worth watching just for that heh heh!!! Really cool vid, very enjoyable :-)
Thanks for the explanation, the diagram is very helpful Just need clarification: I learned that if the electron is going to the right I learned that if the electron is going to the right And if the magnetic south is in the page (magnetic field pointing in) Then the electron is supposed to go down I couldn’t connect this rule with your diagram Could you Help me make the connection?
Hello hay do they have to be the same as the number on sensor ??? I just made a order for my EBike throttle with a 3 prong wire but the numbers are different from the regular one??
i am considering to use the hall effect sensor to determine the depth of a current carrying conductor burried underground( about 30cm). i am not sure if that is achievable.
can you help me with my problem. I have a 2006 SAAB 9-3 and the sunroof doesn't work. Can it. be a faulty haal effect sensor and how do I find them and test them.
Hwzit how you uncle. Really hope you can help me . I've got a kadett 1.6 carburetor with electronic distributor. The pick up coil in distributor according to my knowledge keeps burning out or faulty. . Bought so many now. Bought pick up coils . Ignition module and ignition coils . And I'll drive a day or to etc and all of a sudden I'll loose spark. I do know what I'm doing however maybe over looking something. So my question is. What would cause the pick up coil in distributor to stop sending signal.
Does Hall Effect Sensor measure the spindle speed of the motor too? Electric scooter for example. And does this be needed for accelerating the motor? Or can the speed throttle do the job without the Hall Effect Sensor?
hi, I have amt602v36-1000 servo motor...pls guide me what type of amplifier should i use? Is there a programmable amplifier also available in the market?
How do I contact you? I've got an actuator with a Hall Effect motor that has a circuit board. I'm still trying to understand it well enough to be able to explain it to the engineers where I work and I'm basically a technician. One of them told me it was too complicated for him to understand it.
Was this an April first video? This isn’t how any Hall Effect sensor works, to my understanding. The Hall Effect is based on something known as Lorentz Force. A local magnetic field induces a voltage potential at a right angle to itself AND an electrical current (it does NOT suck electrons up into the magnetic pole). There are no secondary capacitively coupled “sense plates” - the voltage is induced in the single current carrying “plate” at a right angle from the path that the current is flowing. The voltage potential difference is in the order of microvolts, so the sensor has voltage regulation, op amps, as well schmitt triggers built into the sensor packaging to bring the signal up to the level that external components can reliably use them.
Reuben U No offense intended - it's just that no one knows. Cathode ray tubes use electromagnets to bend the beam. Thought it would help you understand.
Hi Daniel, im working with hall effect sensors, and recently, something is going wrong. The sensors sense when they are not supposed to and vice versa. Now that i looked your video, i think it might be the wires, so what do you mean by cleaning them? Thanks
Fernando Calatayud Zepeda Can't be certain. What is this on/for. Manufacturers have been known to screw up; it is possible wires are crossed. Check that first. Cleaning wire connections is what I'm talking about.
sir i hv a question sir .........these hall sensors r used in manufacturing of electronic compass which r fabricated in our modern phones wont it be affected by the other magnetic fields produced by other components present in our phones?
Cool thanks for the share. I do have a question thow. Ok I have a 48volt 750 watt gearless hub motor that goes to my trike mobility scooter. The wires broke of flush on the wiring for the hall effect sensors, but there is a few different ones on Amazon for a few bucks. I'm guessing it is the 3144, but not to sure. Can you help me? Thanks for your time. Joe g.
Reluctance is magnetic resistance/conductance. If the material the magnetism is passing through changes, the strength of the field changes - and then that can be used to affect current in a wire. Magnetism hates air and loves soft iron.
I would like to order your training kit ! I sent a payment through paypal.....but it didnt go through for some reason, can you tell whats the best way to order?
Dan I enjoy the information you impart, however I wish you could have your diagrams already made up in advance as it would speed up these videos. It seems you are talking to a 9 or 10 year old during these explanations. I've yet to see a 9 or 10 year old employed as a diagnostician. Please understand we need to be talked to as adults and not kids. I believe this is your intended audience in all of this is it not?
You trust Wikipedia? I trust my electronics teacher - and remember who I teach. If it's really wrong - give me the link you your video explaining it the way you think it works.
Daniel Sullivan my concern is can a defibrillator be shielded from the magnetic field temporalie. I am a welder contiplating the installation of a pace maker dfib.
Some of us work for a living. Part of the filth is from wiping off the bullshit from comments like yours. Thanks for pointing out my need to avoid lingering around persons of your ilk.
very good video, but you very slow in drawing and speaking (a lot of time wasted). 25000 view if it reduced to 15:50 25000 min saved! i believe it could be 3 min video with the same content and drawing. thanx anyway.
Some people want to know how a watch works. Apparently you don't. Some people just need to know when it's time to drop the dip and chips and go online to lash out rudely against someone they don't know who's trying to teach. Thanks for your observation. Please refrain from using anything my video *might* have taught you.
_Right, some people want to know how a watch works..._ So if and when they ask that question, it's quite unecessary to randomly tangent off into gear tooth profiles, pressure angles, backlash, material science, lubrication, vibration analysis etc. while giving that explanation. Do you see the trend there? This is about _FOCUS._ Maybe my "criticism" wasn't clear in my original comment. Although, I WAS very careful to avoid being condescending or judgemental, unlike you were in your reply. In my opinion, one of the most valuable traits that an *effective* "educator" can posess is the ability to accept, assimilate and adapt their style via constructive criticism. Let me break it all down for you: You labeled this as an *_ESSENTIALS_* video. With "essentials" being defined as "only that which is _absolutely necessary_ for understanding or function." BUT, it took you over SEVEN minutes of a nearly 17 minute video to even _DRAW_ a picture of a three-pin hall sensor. Which followed seven minutes of magnetic N and S poles, field lines, vacuum cleaners (WTF!??) - all of which added NOTHING to help the building of anything that resembled an understanding of these things. I'm all about analogies, and I use them ALL the time. But they can't be used within an explanation without careful thought and restraint or they _themselves_ become sub-topics requiring explanation, all of which can turn a relatively simple topic into an endless incomprehensible one. Rest easy, you weren't about to teach me _anything_ on this because I already have a solid working knowledge of hall sensors. However, I DO occasionally search around and see if there is any additional information that I may be able to add to my mental library on the topic. A hall sensor in my own words: A three pin (typically) device that gives an output in response to an applied magnetic field. It requires a connection to a voltage source using it's + and - pins and depending on the specific sensor chip being used, the voltage on it's output is either discrete or can vary in an analog fashion anywhere between the voltages applied to it's power pins (proportional). The discrete type will output a high or a low signal when a field is present (dependent upon the chip) and return to "normal" when the field is removed (non-latching type) or it can require that the opposite magnetic pole be applied to return to it's "normal" state (latching type). The analog style will give an output that varies proportionally to the strength of the applied magnetic field and is usually centered around half of the input voltage applied to the + pin. For a 5v proportional sensor, it's output will vary from 2.5v (no field) to 5v (max field) when exposed to the N pole of a magnet or from 2.5v down to 0v (max field) for the S pole, again the specifics will be device dependent. ...and **THAT** is a textual example of the _essentials_ of hall effect sensors...
bro..u could have explained in a proper manner than drawing bullshits ( xD ) ...i dint understand anything honestly and ahh..umm...if u hav any other video which explains very clear pls lemme know that...thank you..and yeah i liked ur video :)
Umm, bro - I got nuthin'... Can't draw bullshit, BTW. I think you were looking at my chickenshit drawing, and maybe you just "dint" understand the difference. Chickenshit is white, and bullshit is brown, as I'm certain you know. "I don't give a shit" is invisible, which is why it's so deadly...
hahahaha.... u dont know what bullshit means and you start talkin about chickenshit.. haha wonder why you couldn't explain in a proper way. well this explains more than enough that you suck.. really SUCK at explaining something to others hahahha.

The Creativity Is Really Appreciated....people hardly have this much of imagination power.
Thanks I like the way you explained. For me this is the best explanation I had in U tube, very methodical and I am glad I found your video.
Thanks Dan, still having a positive impact after 3 years!
Also, I have learned to reinforce a learning concept, good for students, make drawings of the details of function or theory and inject a little fun, a picture remembered is worth its weight in gold.
You sir are a phenomenal teacher 👏!
I appreciate your time and explanation for this!
Thank you!
Mr. Sullivan's FET book changed my whole career. This guy knows what he is doing. Thank you Dan!
Well heck - you're welcome. Glad to do it, glad to know it helps, and glad to know you're better off for it. Feel free to email with questions. Stay safe.
Daniel Sullivan
I love every video made by Dan Sullivan. Greatest electronic teacher I've learned from yet. Wish I could have him as a teacher.
Thanks Mr. Sullivan good work
Very good explanation. Thanks.
Great teaching. Pls come out with another book on OBDII and sensors operation and how to troubleshoot them using digital multimeters
I am now fully edumaverified in the dark art of Hall effect sensors. Never seen electrons drawn as zoomin' groovy little guys, almost worth watching just for that heh heh!!! Really cool vid, very enjoyable :-)
Thank you Mr. Sullivan for the video. Much appreciated. Also enjoy studying your book. Thanx again sir
you explained it great ☺️
such a great explanation
very good explaining
Very nice teacher!
Thank You very much, Daniel!
Very well explained great job
I like the special sound effects at 6:07.
Great explanation once again. Thanks. When I hear the term hall effect I think automotive tone rings on axle shafts,
Loving the artwork, great video, entertaining and educational, keep up the good work, I have no idea why you get thumbs down! All the best
You are hilarious. Also, I learned a lot. Would you like additional feedback?
thank u sir it is really a useful and conceptual explanation.
+Amit Sharma You're welcome.
Great video, thank you.
Good explanation Dan
Thank u sir👍
Use them in my work, all day long... :-)
thanks dan
Very good
Thanks for the explanation, the diagram is very helpful
Just need clarification:
I learned that if the electron is going to the right I learned
that if the electron is going to the right
And if the magnetic south is in the page (magnetic field pointing in)
Then the electron is supposed to go down
I couldn’t connect this rule with your diagram
Could you Help me make the connection?
is a Hall effect sensor a NPN transistor and/or can it be tested the same way ? BTW I bought your book , I may just learn something.
I didn’t learn a thing, but I loughed quite...
Love thy dude
. Thanks my friend.. It does something.... LOL 🤣🤣
Good job.
I better get his book/Load Pro combo before too long.
Awesome man!
Hello hay do they have to be the same as the number on sensor ??? I just made a order for my EBike throttle with a 3 prong wire but the numbers are different from the regular one??
There are hall effect sensor used in combi boiler here in the UK. That's why I am here viewing this tutorial on how these sensors work. 🙄
can you use any magnet? Does the size matter, like would a very strong magnet kill the sensor?
I think it would over kill the signal from the sensor. 🙄
could a 24v controller handle a 36v battery
How to replace a hall effect sensor with a potentiometer the correct and safe way? Where to start?
Voltage. Function. Location?
i am considering to use the hall effect sensor to determine the depth of a current carrying conductor burried underground( about 30cm). i am not sure if that is achievable.
can you help me with my problem. I have a 2006 SAAB 9-3 and the sunroof doesn't work. Can it. be a faulty haal effect sensor and how do I find them and test them.
Schematic and operational description? Without them, no, I cannot.
Hwzit how you uncle.
Really hope you can help me .
I've got a kadett 1.6 carburetor with electronic distributor.
The pick up coil in distributor according to my knowledge keeps burning out or faulty. .
Bought so many now.
Bought pick up coils .
Ignition module and ignition coils .
And I'll drive a day or to etc and all of a sudden I'll loose spark.
I do know what I'm doing however maybe over looking something.
So my question is. What would cause the pick up coil in distributor to stop sending signal.
Wire problem. Intermittent open. Corrosion. Wire 80% of the time. Don't change parts until you confirm the wiring isn't damaged.
Does Hall Effect Sensor measure the spindle speed of the motor too? Electric scooter for example. And does this be needed for accelerating the motor? Or can the speed throttle do the job without the Hall Effect Sensor?
How would you say hall effect sensors compared to piezo-resistive strain-gage based sensors?
great tutorial but watch it at 2x speed
Good think...
does the iron thing have to be magnetized?
thnx sir
hi,
I have amt602v36-1000 servo motor...pls guide me what type of amplifier should i use? Is there a programmable amplifier also available in the market?
Hall Effect Sensor is obviously a sensor because it senses something.
SUMMARY: watch with x2 speed from 6:25 to 10:34
How does the DCC or Direct Current Comparator works ?
was this just an excuse to draw a vacuum cleaner?
he went full vacumm cleaner there
How do I contact you? I've got an actuator with a Hall Effect motor that has a circuit board. I'm still trying to understand it well enough to be able to explain it to the engineers where I work and I'm basically a technician. One of them told me it was too complicated for him to understand it.

The voltage potential difference is in the order of microvolts, so the sensor has voltage regulation, op amps, as well schmitt triggers built into the sensor packaging to bring the signal up to the level that external components can reliably use them.
If the electrons are going toward the south pole of the magnet, does it mean that the south pole is positively charged?
+Reuben U If you figure that out I'm pretty sure that you'll win the Nobel Prize in Physics. Read up on electron beam guns and cathode ray tubes.
Daniel Sullivan
Geez, I was actually just being curious. Anyways, thanks for the advice.
Reuben U No offense intended - it's just that no one knows. Cathode ray tubes use electromagnets to bend the beam. Thought it would help you understand.

About the vacuum, you forgot to turn it on.
I am working with an LEM LA55-P. I am not sure where to set the transresistance (in multisim) . Any ideas?
+Chris Hill Wish I could - I don't have that level of specific info or experience. Sorry. I'm kind of stuck in an electricity 101 rut...
sir i hv a question sir .........these hall sensors r used in manufacturing of electronic compass which r fabricated in our modern phones wont it be affected by the other magnetic fields produced by other components present in our phones?
They can be - unless they're otherwise shielded or protected. Excellent question. Smart...
Thank u sir:-)
Cool thanks for the share. I do have a question thow. Ok I have a 48volt 750 watt gearless hub motor that goes to my trike mobility scooter. The wires broke of flush on the wiring for the hall effect sensors, but there is a few different ones on Amazon for a few bucks. I'm guessing it is the 3144, but not to sure. Can you help me? Thanks for your time. Joe g.
Can you send an image? dan@brighterideas.com
joe gonzales. same happened to me!
Good tutorial but electrons don't move through the sensor, that would basically be an arc which is not good.
+rfjgfude Yes they do. That's how a hall effect sensor works.
What about the difference between Hall effects to vrs sensors
Reluctance is magnetic resistance/conductance. If the material the magnetism is passing through changes, the strength of the field changes - and then that can be used to affect current in a wire. Magnetism hates air and loves soft iron.
Where to buy your book ?
Now I'm more confused...
I would like to order your training kit ! I sent a payment through paypal.....but it didnt go through for some reason, can you tell whats the best way to order?
Contact www.esitest.com .hey'll be selling them now. I ran out of all I printed. Sorry. Should be available in a couple of weeks.
ok thanks.
nice
10:04 you're welcome
professional
👍👍
So you’re drawing of your vacuum looks like a bumper car
why do some people write to o's to make an eight?
Why do you show the Illuminati sign with your hands in the start of your video?
You could have made that vid less than 5min
+Dave Fd How do you know I didn't?
+Dave Fd Beautiful and informative, so no offense but 1.5x speed worked fine for me
Hi
So much digressing
Dan I enjoy the information you impart, however I wish you could have your diagrams already made up in advance as it would speed up these videos.
It seems you are talking to a 9 or 10 year old during these explanations.
I've yet to see a 9 or 10 year old employed as a diagnostician.
Please understand we need to be talked to as adults and not kids.
I believe this is your intended audience in all of this is it not?
No
too slow, even at higher speed (it would be better if it was prewritten / predrawn)
You're obviously not a teacher...with 35 years experience in the trades-technical classroom. If you don't like it - don't watch.
😂
Not an accurate explanation. Absolutely not. Go to Wikipedia, Hall Effect.
You trust Wikipedia? I trust my electronics teacher - and remember who I teach. If it's really wrong - give me the link you your video explaining it the way you think it works.
What a waste of time
Second only to cock fighting...
Daniel Sullivan my concern is can a defibrillator be shielded from the magnetic field temporalie. I am a welder contiplating the installation of a pace maker dfib.
I honestly don't know - you'd have to ask the defib manufacturer. I'd doubt it has an effect.
Too dumb I think trying to dumb down a technical subject is a insult to the persons intelligence
im looking for a explanation not an art class
Then you shouldn't watch my videos. Feel free to look elsewhere. Thanks for the pointless sarcasm and rudeness.
DORK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
it gets too boring and to long
I forgot the first part allready
Why did I get bored?
+Espen Bøgh Got me. Because you're a troll without a clue and a with a short attention span? Just a guess...
If u r gonna do this kind of vides please clip your fingernails it's repulsive
