These linear magnetic sensors work as advertised. They can detect the fields of small neodymium magnets (3mmx1mm) reliably without saturating from a few mm distance. The parts are a little noisy like all integrated hall effect sensors, so it's a good idea to use some analog or digital filtering (or both). I didn't measure the actual noise but I am getting at least 60dB SNR with 1 second of integration time. Drift and gain differences are also "good enough" for my application (as an absolute magnetic rotary sensor). I would buy them again.

Just what I ordered. Have not put any of the product into service, yet.

These worked great and just want I needed. Packaged well and in perfect shape when I got them.

These are okay for a neodymium magnet at a centimeter or so if it's strong. My plan was to build this into a EMF probe so that I could sweep banks of relays and solenoids on solenoid valves at work and make a useful tool out of it. It is not sensitive enough to read an electromagnetic coil even if it's right up against the side of the valve or relay.I'm still giving them five stars because it works and it is as advertised but I was hoping for more sensitivity.

I use these for magnetic field strength sensors, they work great at a very good price.

Not linear as the ad says. They are a 1 for that, but 5 for a dectector.

A little inaccurate but worked well for my application
