Could an external capacitor be used to add some filtering to the noisy readings?

Hi, anyone has used the built in hall effect sensor with interrupts? my goal is to count revolutions of a wheel (Bicycle), son can calculate speed. So, I want to use the built in sensor, and got 2 problems: first, can´t figure out how to make an interrupt on each revolution, lots of projects already solved the problem using an external sensor; the second problem, is that the initial value of the sensor (without and magnet near) is different for my 4 Esp43 Wroom 32U boards, so the function I made doesn´t work well for all of them.
