Have a Question? See What Others Asked

Does voltage vary by the magnets distance (strength) or is it full on or off like contact closure?
One amazon reviewer answered that this works at 3.3 v. that might not be true. the specification says "operating voltage 4.5v to 24v." is this true?
what is the maximum speed of this sensor? will they be able to detect at 20kHz for a 20k rpm motor?
How are these wired? There are no clear labels on the board (unless you count 'S' and '-')? What are the three pins?

Worked great!

Installed this on an RC truck wheel with a magnet glued to inner rim. Read it into an Arduino Mega with a library code using I2C interface to get ground speed (wheel rotations). Worked like a charm!

Good sensors

It was great the hall effect sensors are efficient and effective.

Hall Effect Magnetic Sensor Module, 3144E A3144 by MUZHI(6 Pcs)

This order contained 6 pieces of Hall Effect Magnetic Sensor boards. All 6 failed in that immediately upon 5 volts and GND being applied to the board the onboard LED would come on indicating that the S lead was low and testing proved that to be the case. All 6 boards contained 3144 sensors and upon replacing one of the failing board's 3144 with a new 3144 that I had purchased separately that board worked correctly in that no LED upon power being applied and a magnet in the vicinity of the new 3144 turned on the LED and the S lead went low as expected. A good guess based on the above failing board's 3144 being replaced would indicate that all 6 boards have a batch of bad 3144.Did not contact the seller or attempt to have them replaced them since I only needed 1 working board and it appears that repairs can be made with new 3144 as needed so not worth the effort.

Nice confined setup

First order came and only 3 of the hall sensors worked. Sent back and they sent me 6 more. 5 of them worked.

A good sensor works great, but expect only about 28% of these to be good

I bought a set of these sensors to find out if they would work for detecting operational cars in a model railroad. I knew from reviews that yield could be questionable, but I only needed one so that didn't concern me. The sensor turned out to work so well that I decided to replace the IR sensors I had been using on my test track to detect train positioning (too finicky, too many adjustments needed, too sensitive to light) with these. All six sensors I received performed as expected, worked reliably, and didn't require periodic adjustments -- definitely a 5-star experience. So I told my friend to order these for the room-sized rail yard we are building at his place.That's when we started experiencing what has been covered in several reviews. A good sensor works reliably, and once installed seemingly never has to be dealt with again. But a lot of them don't function as expected as they latch instead of only signaling when a magnet is over the sensor. I was concerned over whether a working sensor might become latching at some point, but I've yet to see a working sensor fail, even after I inadvertently reversed the +5v and -5v wires on one.Of the 72 my friend ordered only 21 worked as expected. From a second order of 60 only 16 performed as expected. That gives an overall yield of 28% on a sample of 132 parts. In my mind that's a one-star product, except that we've been able to get a refund on the bad parts without any problem so I figure it evens out to somewhere in the middle.Bottom line, if you don't mind ordering 3-4 times the number of sensors actually needed and are fine dealing with returns, I would highly recommend these sensors. Just be prepared to screen them before installation.

Worth the price

Works amazing. Use smaller magnets for more percision

high DOA rate

3 of 6 sensors received were faulty, latching on pole swaps, as indicated elsewhere in the reviews. How it is possible to mess up a hall sensor, I don't know, nonetheless, be willing to accept high "dead on arrival" rate if ordering. **two stars vs *one, because half of them I received do work, and I only need one, and I expected the fails from reading reviews.

Very cool

Not only did these work well, the electromagnetic concept they demonstrate is trippy
