2 Basic Project with Hall effect Sensor

Hi ,
This video is to show you the basics of the hall effect sensor.

Perfect demo of how hall effect sensors operate with a magnetic field being applied. Exactly how abs braking system measures wheel rotation in an alternating magnetic field

One "Normally Open" and One "Normally Closed". Nice!

I am brainstorming ways to use one or more hall effect sensors to create some sort of biofeedback for myself (I know very basic but definitely effective). Instead of bringing a magnet close to the sensor I would like to get the 'reverse effect directly from a person's physique (me) and so on. it would be useful to be able to discharge the electromagnetic fields caused by the use of smartphones, tablets, etc. Do you understand my point of view?

What is the maximum distance that can be maintained between the magnet and the Hall sensor at which it reduces effectively?

[DoctorEVplus]

Please answer by how much distance does the Hall sensor change the magnet?

Sir, led chaser ke liye ya fir led flasher k liye kuch smd Wale resistor aur ic bata sakte hain app plz

[fun_ny.]

Hlo sir 2nd circuit ka ic nomber kya hai

[MrBobWareham]

I used to use the latching version that you can use like a switch to turn on of a circuit

Poderia fazer um projeto para acionar relé de 12v

[sayanmisra]

Can you please give a schematic or a circuit diagram for the 2nd circuit please?

[krishbhoir]

If i replace buzzer instead of led can buzzer blow

[shivamgupta-mcbt]

I tried but it's not working please share schematic diagram
