Hall effect sensor registers magnetism. In its simplest form, the sensor operates as an analog transducer, directly returning a voltage. With a known magnetic field, its distance from the Hall plate can be determined. Using groups of sensors, the relative position of the magnet can be deduced.

Electricity carried through a conductor will produce a magnetic field that varies with current, and a Hall sensor can be used to measure the current without interrupting the circuit. Typically, the sensor is integrated with a wound core or permanent magnet that surrounds the conductor to be measured.

Frequently, a Hall sensor is combined with circuitry that allows the device to act in a digital (on/off) mode, and may be called a switch in this configuration.

Specifications:

  • Manufacturer: ALLEGRO MICROSYSTEMS
  • Type of sensor: Hall, non-latching
  • Case: SIP3
  • Measuring range: 50...330Gs
  • Operating supply voltage (Vcc): 4,5...24V
  • Max. supply voltage: 28V
  • Operating temperature: -40...85°C
  • Output current: 25mA
  • Mounting: PCB

Pin konfiguration:

  • 1: +5V (Vcc), Used to power the hall sensor, typically +5V is used
  • 2: Ground. Connect to the ground of the circuit
  • 3: Digital Output. This pin goes high, if magnet detected. Output voltage is equal to Operating voltage.

Tips:

  • Connect a pullup resistor to keep output high (eg. 10Kohm) when no magnet is detected.
  • Connect en 0,1uF capacitor to filter any noice that might be coupled with the digital output.
