used a few of these with some rare earth magnets to detect collision. There is hysteresis so after getting close and moving away your will still get a high signal voltage until moving even further away than the initial detection distance. The magnet orientation (and pole) must be correct relative to the hall sensor.

Arbeiten top, wenn man erst mal raus hat, wie sie schalten.Der Ausgangspin wird "nur" nach Minus gezogen, gibt also keine Spannung aus.Somit lassen sich am einfachsten PNP Transistorn damit ansteuern.

Ils marche sans probleme avec un Arduino.Je vais expliquer avec un peu de Franglais !!Trois broches - 1 +ve, 2 gnd, 3 signaux.Connecter 3 a un 'input digital' sur l'arduino et utiliser pinMode(HallPin1, INPUT_PULLUP);HallPin1 est votre pin.,INPUT_PULLUP sets the digital pin to +5V.When the sensor operates it is pulled to gnd,So, reverse logic,Switch = digitalRead(HallPin1);When Switch = HIGH the sensor is OFF
