I needed to measure the magnetic field of some magnets for a fix I'm making and this was exactly what I required.I had it connected to an arduino uno pretty quickly and was able to take measurements to compare two different magnets.It'd be nice if they linked a datasheet directly to this listing but I did figure out that the pins are as follows when counting left to right when the text on the sensor is facing towards you:1: vcc2: ground3: output

Worked fine as a replacement for another 49E in a motor speed controller. Only complaint which is not specific to this item, they're difficult to solder. I find many components won't wet without physical cleaning with abrasive. This is one.

It does work after replacing it for the third times. I guess that what China stud do for what it does.

Good value and performance. Output current is limited, I suggest a suitable single supply rail to rail opamp, e.g. MCP6000 series. The usable range is about +/- 1000 Gauss, just about right for most guitar pickups.
