I’m new to the world of magnetic sensors need some help understanding and find the right components for a HALL (?) sensor application. The Idea is to measure the position of a magnet with diameter of 5mm and 1-2mm thick.
The magnet will have a Zero point and from there it can move 4mm to 6mm.
I need to measure if the magnet is at the Zero-point as a more or less digital value and then I need to measure with some precision if the magnet is in the range 4-6mm. Preferably with 0.3mm resolution or better.
The HALL-sensor must be positioned 5mm from the magnets travel path, but anywhere along the path.
I need suggestions for both the magnet and the sensor.
