## Description

Bestol 10Pcs A1302 Ratiometric Linear Hall Effect Sensors Chip

Review: Good product - I am using these to make a "potentiometer" using 5mm round magnets. They work great and so far very reliable. I would recommend.
Review: This is a quality Hall Sensor and I am faster because of it. - I used one of these Hall Sensors to change my Sim Racing Throttle pedal's 10k Potentiometer. It was a total hillbilly hack but works like a champ. I have been a sim racer online since 1999 and as we all know, potentiometer's are going to eventually get flaky and wear out. I ran across an example on a racing forum and decided to attempt the change. Using 2 Neodymium Disc Magnets, a plastic top from a pharmacy pill bottle, hot glue, and the old 10k pot since it was already there. I simply disassembled the pot, pout a hole in the top and cut it for clearance, glued to mag's to it, glued the sensor to the pedal and wired it up. It's the most responsive pedal I have ever used. I am already running faster laps directly because of this sensor. It's tough, and can be reverse wired without harming it. I was not easy on them and they show no flaws.

## Questions & Answers

**Q: What is the range of this sensor? Over what amount of distance can it detect a field?**
A: I'm using these for a simulator project using fixed magnets. The magnets on my simulator controls are about 6 mm from the chip and I get a good signal for my control purposes. When they first arrived I did a quick (though not terribly accurate) test to see how close I needed the magnets to get a good signal. Beyond about 15 mm wasn't workable, and inside about 10 mm produced a workable signal.

**Q: are they unipolar?**
A: I'm going to answer this question even though I haven't seen the term "unipolar" come up in discussions regarding building Hall effect hi-hat sensors for electronic drums which is the application I'm involved with. The side of the chip that's beveled is the north side. The flat side opposite is the south side. I discovered that on my own during my second build when I had to turn the magnets (scavenged from hard drives) upside down. At first I thought it might be my wiring but then I noticed I had glued the chip in facing the opposite direction. I'm hot gluing these inside a polycase project box and then wiring them up to a TRS female jack.  Center is ground, left is +5 volt power to chip and the right pin is the output that increases as the magnet approaches the chip.

**Q: What are the pin outs?  Is there a datasheet?**
A: With the beveled side facing you the left pin is +5 volt chip needs to operate. The center is the ground and the right pin is the variable output depending on the magnetic field it senses
