Well I don't like that I don't have as good as eyes as I used to.Makes it hard to solder small things.

Tried multiple of the sensors, none of them actually detect magnetic field.

Alright, alright, alright, let's go. OK, so, the information listed on this product is abysmal so I'm going to attempt to give you what you need to know. First off, these are linear ratiometric sensors. As another reviewer accurately posted (and thanks to them for posting it) these sensors sit at a quiescent output voltage of half the source voltage when no magnetic field is present i.e. 2.5 volts if using a 5 volt source (power supply) voltage. The closer the north side of a magnet comes to the sensor the lower the output voltage will drop from 2.5 volts down to ~0 volts. The closer the south side of a magnet gets, the higher the output voltage will rise from 2.5 volts up to ~5 volts. I was able to directly replace a 10K potentiometer, use for an analog axis on a joystick board (Leo Bodnar board) with one of these. Pin 1 is the Supply voltage pin, pin 2 is the ground pin and pin 3 is the output voltage pin. The first one I tried worked perfectly, still have to test the rest. One reviewer said the magnet had to be very close but I didn't find that to be the case. Using a strong neodymium disk magnet, half the diameter of a dime, which I also purchased on Amazon, I was able to start getting a voltage change somewhere around 2 1/2 to 3 inches from the sensor when coming at it head on towards the beveled front of the sensor. Be very careful not to overheat these when soldering to them, flux and pre tinning your wire is your friend. These sensors are very small, about half the size of a typical through hole style transistor package. With the magnets I used, checking the raw data value range on the Joystick board calibration page in Windows, the range was not quite that of a pot. 10k pots were going from around 0 to 1022 digital range while this sensors range was from about 150 to 900 on the 12 bit joystick board. This may change with a larger magnet or different placement so your mileage may vary. Still, good enough for my purposes of converting my DIY flight sim pedals from pots to hall effect sensors. Unless too many of these turn out to be bad I'd highly recommend these to anyone making or converting controllers for flight or even driving sims. Best part is, for around 10 bucks, I know have 19 more of these to get creative with and use for other projects.
