I can say it is the best demonstration of hall sensors. It helped me a lot! * Note: I think if you approach through the other side of those transistors you'll get the same effects, using inverted magnetic polarity though.

Nice to know that helps you. You are right; if you approach from the back with the reverse pole facing the front, it will have the same effect.

Thanks for sharing. for the future: can you please mention part numbers you test? This would help us alot.

How do I go about converting; a hall sensor up/down selector wheel, that sends a signal for a motorcycle dashboard via 2 wires; to two separate momentary simple switches? can someone help?

Hi, Have a good day. Thanks for the video and explanation. I have a question if you have any advice. We are planning to count the rotation of our device. We designed a ring and placed some material on it that can produce a magnetic field, and we connected this ring to the device which will rotate. Then we placed a hall effect sensor( ALLEGRO 3214) with a transmitter and put this transmitter close to the rotational part and ring. Which sensor could be better for counting the rotation number by magnetic field?

Hi, it seems that your choice is good. I just have advice regarding the material to generate a magnetic field: use neodymium magnets.

I've seen a couple of keyboards that feature hall effect mechanical switches. Do you think it would be possible/feasible to try to create (3d print) my own switches for a keyboard/computer device, starting with these sensors?

do you have an idea which sensor can detect magnetic presence doesn't matter the magnet polarity, and it can detect it in 360 degree which can be read into analog output.

For this case you need a magenetic encoder, the chip that can do the job is AS5048B or AS5030.

But how do we turn On with North Magnet ( I think one has to approach the broad face with N magnet) From experience more than 5.5 volt in put causes the HED to fail even though they are supposed to go to 20 volts

I have a question if you dont mind answering if you know, inneed to change a hall sensor in cricket ball throwing machine, i purchased some bipolar hall sensors, but when I have installed it, my voltage to the sensor is 5v but when i get voltage out it drops to 3v, do i need a linear sensor as i need it to show 5v. Thanks in advance if you know, im asuming its the linear one from this video. But as you may know, to assume things make an ass out of u and me 😂

Linear hall effect sensors are used for positioning and the output is analog, check this video kzread.info/dash/bejne/g5mcprKrgt2_edo.html . Maybe the bipolar hall sensor is right and you have other issue in the electronic circuit.

any model numbers for each type?

The hall effect sensor lends itself in many uses. I am interested in the 'electromagnetic aspect, to discharge from the human body precisely the electromagnetic field generated by smartphones, tablets, etc. A kind of low-cost Biofeedback. I don't know "if" you understood what I meant?

Yes, it is a good idea, however I am not so sure if the magnetic field generated by the human body is strong enough to be detected.

Seems that your sensor is 49E, linear hall effect sensor. It means that the sensor produce analog output.

if the output of the sensor is on ground, does it reverse the polarity of how the magnet functions?

@engthink

No, don't work like that. To reverse the output need a transistor on output.
