This video will describe how to build your own proximity sensor using linear Hall effect sensors. This sensor will detect ferrous targets and output a digital signal that can be sent to a microcontroller for processing.

As usual, the first word you start your video with is "OK..." ... Great video

I used this sensor for detecting when the motor is stopped.useful video

Howdy! Came across you video a week or so back and have watched it a few times. Love the simplicity of the project. My problem is I am trying to build something similiar, but need it to detect a ferous object 3 ft to 6 feet away. How would I megasize this to work. Thanks!

That could be a challenge. Try looking into GPR (Ground Penetrating Radar)

is the more gears the more accurate the rpm measurement using the hall effect sensor?

I'm a Forth guy too. How much effort is required to get Forth running on an Arduino?

What is the smallest-size ferrous object that can be detected with this setup? For example, could a stainless steel (ferrous) needle be detected?

@0033mer 6 жыл бұрын

No ..That would be too small to detect.

Great Content! Can this circuit also build up with an NE 5532P (or one of these OPAmps i have: LM324N, LM339N, ULN2003AN, ULN2803APG, LM358P, LM386, LM393, NE555P, UA741CN, JRC4558D, PC817). I am new in electronics so i hope this question is not too silly ;-)

Any general purpose op-amp will work. The NE-5532P will work. Build the circuit and experiment with different magnets as shown in this video: kzfaq.info/get/bejne/bZhzeryF36e8YHk.html

can i use a3144 instead oh49e?

The circuit was designed for linear hall effect sensors. You can get the same circuit in automotive sensors. kzfaq.info/get/bejne/lZOPi6p90LHSc6c.html

Why an op amp instead of a comparator?

@0033mer 6 жыл бұрын

A comparator would be a better choice. They are designed to be used in open loop configuration, fast switching, and rail to rail output. I used an op amp because most people will have one available in their parts bin. If a comparator is available like a LM311 that would be a better part to use. Just remember the output is open collector.

0033mer thanks for the detailed answer. Op amps are still magical to me, but I suspected a comparator would do. What I found most difficult to understand is why a particular op amp was chosen for a given circuit, as most authors do not elaborate on the subject.

Álvaro M. Valdebenito B. Yes , I was wondering that too. That deserves a video.
