Basic Hall Effect Sensors 1

[@unfundedopportunities7278]

Your webpage "Introduction Hall Effect Switches Sensors Circuits Tutorial" was VERY helpful. Thank you for posting. The UGN3013, or something similar, is what's inside the Intake Manifold Runner Control Actuator for my Ford Focus - DORMAN part# 911-927. Engine vacuum pulls a contol rod down to close flapper doors inside the intake manifold. The enclosed sensor detects when the rod is down; it was faulty. It looks like hall sensors are used extensively in automotive applications, and trigger the 'check engine' light and trouble codes when they fail.

Many thanks again ! I finally understand the functioning of the 3 types of Hall effect units ! You're really doing a great service to ALL of us. Josef-Olivia.

[@christheother9088]

Great as usual Lewis. Hall Effect sensors are a blast. The ratiometric provides such a clean signal it can be amplified and very small movements can be measured. Much less frustrating than a noisy resistive sensor in my experience.

[@LewisLoflin]

Note to visitors: The part numbers and spec sheets for the sensors used are on the website at the bottom of the page. One is a TL173C, another is UGN3503, and the other a SS466 Hall Latch.

[@professorfidelcat]

Lewis Loflin great video, may I know why does the 3503 seem more expensive than the cheap A3144E types on ebay?

[@LewisLoflin]

It's an older uncommon divice.

[@professorfidelcat]

Lewis Loflin thans for the reply lewis, the 3144e, 10 pc for just over a buck on ebay seems too good to resist buying..

[@LewisLoflin]

I'd go with it - make it does what you want to do. There are different sensors.

[@damondholsinger1632]

thank you so mutch for this video. The Hall effect throttle on my mini bike wasn't working. This helped me find out that it was missing a magnet! Thank you for this video!

[@johnclavis]

Thank you very much for the education. I've been messing around with Arduino for a while and am working on something triggered by an approaching magnet, so this was just what I needed!

[@LewisLoflin]

UGN5303 has an analog output and is not for digital. One would use the latch or switch version. This can be used for digital if you leave out the resistor and connect it to to a comparator circuit such as an LM311. My website has a section on comparator circuits.

[@bebilebi]

Okay, thanks for taking your time to answer and putting your effort into this. Please let me know if you find out something. Best regards /Karolina

[@LewisLoflin]

I used three different sensors for that project. That was a latch part number SS466A from Honeywell.

[@fisalsadoon]

i now actally understand how it works,thanks you so much .i will go a head and do my project .

[@LewisLoflin]

as I listed below I have a solution. Use a Hall effect switch, make sure it has an open collector or drain, a pull up resistor, and use a JK flip-flop. That way you can use the south side of the magnet to cut the output on and off. The output will be taken from the output of the JK flip-flop.

[@LewisLoflin]

A 74C925 is a four-digit counter operating at five volts, so to simply count pulses use the digital out directly to the input. If trying to read an analog voltage, won't work.

[@joripiano]

Thanx a lot for the clear explanation! i'm probably using a Hall sensor (switch) for building an anemometer. (i believe it's more accurate measuring the rotating frequency of an anemometer by using a hall sensor, than measuring a voltage generated by a generator connected to the driven shaft (which ads up to a lot more resistance on the shaft). Thanx again!

[@billfield8300]

Hey Jori, check out www.moderncuircuit.com they have some very kul anemometer breakout boards. Just an FYI...

[@nagarajumummidivarapu3141]

Very Good Theory with Practical Presenation. Thank you.

[@gigicaly]

wonderful site and youtube channel. please keep the how to videos coming :)

[@Electronics61]

Hello Lewis. Many thanks for YT Video. Excellent introduction.

[@bebilebi]

Hello! I wonder if it is possible to get the diode to be switched on and off with the same South- or North Pole of the magnet? Example: you move the South Pole towards the hall sensor --> diode lights up (and maintains that way). Then you move the South Pole towards the hall sensor again > diode goes off. This is for a project at the Royal Institute of Technology in Stockholm County, Sweden and we’d appreciate your help. Best regards Karolina

[@fidelcatsro6948]

wow thanks for the video..hall sensors are like magnetic reed switches..if we want these hall sensors to turn on and off large current appliances, we must connect them to a segregated heave duty relay switch?

[@christheother9088]

Great tutorial. Lean and mean. Thanks!

[@chachadejava]

Thank you for making this video. Is there any type for switch that will do different pole. I need 2 type of sensor which where if South pole coming, it will light a light (you already have in the video). Then if North pole coming, it will light another light. Both sensors will be in same place (closer each other).

[@LewisLoflin]

Click on the link above hall-effect/index and I put the sample code there. I assume you are using a LCD display as I used in the video.

[@B18bVtec]

Normally open hall switch means the light is off till it sees magnetic field?

[@oliviamonkey]

Thank you kindly, it was a big help !! PS: I actually have tried a # 741 IC before . . . it works but the input 50K pot. adjustment is 'tricky' * This also permits me to adjust for 'sensitivity' Thanks again, JosefHRH ;-)

[@wisdom_wellness365]

Thank you so much. Your video is excellent!!

[@billybonewhacker]

cool i have one of forrest mimms books about these but was unaware about the latch wich has alot of possibilities .

[@LewisLoflin]

I believe I have a solution. Use a Hall effect switch with the JK flip-flop. I'll have the circuit done in a day or two I may just go ahead and make a video on it. Lewis

[@Loay.Elbasyouni]

Does 80L mean anything? do you know if hall effect have 80L what does it mean?

[@jameswyun99]

I am trying to replicate your experiment. I am a beginner. I have a battery pack, wire, and LED. Do I need anything else? What do I connect the middle pin (ground) to?

[@MikeWarren]

Do you know of a momentary hall effect switch that is normally open? (the one at 1:00 is normally closed until a magnet is introduced).

[@MoJoM0J01]

You could short the switch to ground in parallel with the light. If that does not work you might be able to find some for a breadboard here www.microchip.com/ and some industrial grade here www.globalspec.com/ds/181/areaspec/output_normally_open

[@lineuve]

Thanks Professor, very nice explanation.

[@LewisLoflin]

Thank you.

[@GhostvaperYT]

HI can someone please help - i have a laptop with a hall effect sensor, the lid opens and the screen turns on when lid shuts the screen turns off. but my screen is always off, i put a magnet to the hall sensor and the screen flickers on/off fast but wont stay on! i got a replacement sensor but its the same !! can a bypass the sensor. its a small chip. at top 2 pins and on other side 1 pin. please help..thanks

[@carlosbarrena3241]

Thanks a lot. Very illustrative

[@colemanlab3361]

Great tutorial... how about an "OH44E" sensor? Should this work the same as the first example?

[@LewisLoflin]

Coleman Lab Should work fine at 5-volts - you do know this is a ratiometric and not a switch?

[@jackhills7474]

Hi there, great video. I'm doing an assignment for my Motorsport Engineering course at college, and I have a question: In a 2-pin hall sensor, what does each pin do? I previously thought that all hall sensors had to have 3 pins (Input, Signal and ground), therefore I'm struggling to make sense of how a 2-pin hall sensor could work. By the way, the sensor itself is a wheel speed sensor. Any help on this would be greatly appreciated.Thanks!

[@LewisLoflin]

+Jack Hills Never heard of a 2 pin Hall effect. Are you sure this wasn't a reed switch?

[@jackhills7474]

I am absolutely certain, as I've heard from multiple sources that it exists. However, if you'd like to elaborate on the reed switch, I'd love to know your thoughts as to why it could be that. Thanks :)

[@vinaycool758]

[@kirknelson156]

question will these work off the magnetic fields created by current going through a wire? i'm planning to make a tachometer for my atv and was wondering if something like this could be triggered by the pulse to the spark plug, without messing with the plug wire, like just by taping the sensor to the wire. is this a stupid idea or do i need to use something different?

[@aw1cks]

I want to make a sim racing wheel and a hall effect sensor would probably be a good alternative to a potentiometer. Do you have any ideas on how I could achieve a design where rotating a wheel could change voltage? Many thanks :)

[@oliviamonkey]

Hi, I have UGN5303UA Hall sensors I'm supposed to use a 50 to 200 Ohm resistor in the drain - There's always a 2.4V voltage present . It's impossible to activate TTL chips this way - Please help PS: You seem to understand very well. Thanks for now , JosefHRH

do you mind to share information what is number for the first hall effect sensor? thx

[@daveyedgar]

would the hall switch sense the magnetic field off of a wire when current is running through it? for example if i put it next to the wire coming off the generator can i get an led to light when the generator is running and off when its not?

will hall effect sensors give accuracy of a copper and carbon brush system of a commutator? Can I change my copper commutator to a magnet version with a hall sensor as the brushless sensor. Also I need voltages of 12VDC - 280VDC. Can a hall effect sensor allow me to use such power to generate into the coils, like a Mosfet.

[@LewisLoflin]

No no, and no. Hall sensors are low power devices. I give a number of examples for driving MOSFETs, etc. www.bristolwatch/hall_effect/arduino_hall_effect.htm

[@samii54321]

Thanks a lot. can u share some video about eddy current sensor?

[@LewisLoflin]

أسامة محمود Interesting idea, never tried that.

[@robwilliams3602]

The ratiometric. Question would you have a good code to upload to a Arduino to work this type of hall effect sensor ?

[@LewisLoflin]

All you do with a ratiometric is read the voltage value though and ADC port on any micro-controller. With a 10-bit such as Arduino understand the output from the sensor is centered on about 2.5V with a 5-volt sensor. Subtract 512 from the values assuming the voltage out is over 2.5V. If it drops below 2.5V use the value directly or turn the magnet around. Note the sensor likely won'y go all the way to 0V or 5V.

[@TRD_Mike]

Great video, thanks!

[@LewisLoflin]

Hi Karolina the answer to your question is no unless one uses some additional electronics. The sensor I was using was is called a latch and that's simply the way it's designed. There might be another way to do this with a Hall sensor let me have a little more information, see what I can figure out.

[@a271711]

Thanks for the video: ) how can I measure a magnetic field which more than 3000 gauss? do I need a hall generator?

[@LewisLoflin]

Stone Derek What do you want to do? A ratiometric Hall sensor puts out an analog voltage proportional to a magnetic field.

[@a271711]

Lewis Loflin I wanna measure a strong magnetic field (like more than 3K G) But the output of the amplifier will reach Vcc first and become saturation... : ( so i wonder that maybe i need a hall generator 、hall plate or sth i don know to design it from origin.

[@LewisLoflin]

Try a bias magnet from the other side.

[@adythings]

Sorry, the code for the one that you use that in the output have a variable Voltage is?...

[@LewisLoflin]

ady alejandro prado salas You will have to use an Arduino or other micro-controller with an analog-to-digital input and then whatever LCD display. I have used two types for the LCD - an I2C and a serial shift register type. Check those out at my main website www.bristolwatch.com

[@LewisLoflin]

The question that i have is what are the code of that sensor that you use with that LCD display... again, thank you for the answer !!!

[@LewisLoflin]

Reading the Hall is simply read the voltage out on an ADC. Make sure the ADC is 5-volts and not 12!

[@FrankLopezx]

are hall effector's better then rotary encoders? any other form of rotary measurements ? side note i was reading about how you got into electronics and one of your old project got me thinking, im talking about your science award back in high school or was it the science fair ? well i wonder what ever happen to that little experiment ? the one where you shoot a ion into a vacuum tube and control its direction according to magnetization polarization, i actually took my old CRT Tv apart 6 months ago while learning about Cathode Ray Tube "CRT" and how they work "focus electron beams shooting the RGB on the screen of the Tv" so getting back to the tv taking apart 6 months ago, i was trying to understand how that whole foreplay happens as this was never explain in any tv explanation video specially the really old one found on youtube such askzbin.info/www/bejne/fZ_PYqmrrM97qtE & kzbin.info/www/bejne/qGSbn4mjraeZrK8 BUT i was trying todo by taking my old tv apart was to make a RAY GUN this was my reason for doing this and not just a ray gun but a gun that can target moving object withing a space or withing proximity ill get it to work one day specially after i learn how to C++

[@pemifayoobe9634]

how did you manage to display the hall effect output unto to the lcd screen

[@MoJoM0J01]

You need a device that can send the correct signals to the LCD screen, and read the signal from the sensor. There might be a decoder chip available for specific LCD screens, or if you have a robust chip you might be able to send the correct signals. I suggest you check this chip out, it can read most sensors and write to some LCD's. www.microchip.com/wwwproducts/Devices.aspx?dDocName=en010280

[@LewisLoflin]

I connected it to the analog input (ADC) on an Arduino.

[@LewisLoflin]

Lewis Loflin You can use this example just change out the humidity sensor, read the ADC, multiply by 5/255 and display the value. www.bristolwatch.com/arduino/arduino4.htm

At 4:00 minutes into the video you advertised what is inside hall effect sensor. You end up saying that it consist of regulated voltage ( what the hell is that?). However in your diagram it seems to metion "Hall element" which you didn't mention. Now what the hell is that " hall element"?. Regulated voltage. Hall element, meaningless terms, deliberate, senseless obscuration. What is that shit, "hall element" is made off, is it hydrogen, is it lead, is it zinc, is it aluminum, is it some gold, is it uranium, is it rust. What the hell is it? What are its dimensions. how thick, how wide , how long? What the hell is differential amplifier, is it urine? snot? What is it? It is hard to get a straight clear god damn explanation by anybody. You go from video to video for hours and barely get something straight. Are we human beings across the board a bunch of bullshitters. The answer is obvious. Everybody is busy dazzling people with terminologies. Oh they can't wait to spit out the latest words they have learned. They can't wait to Spits it right at you.
