  3. A3213 Hall Effect Sensor
    Rating:
    100% of 100
    SKU: 014-A3213EUA-T
    Unlike other Hall-effect switches, either a north or south pole of sufficient strength will turn the output on; in the absence of a magnetic field, the output is off.

  5. Hall-Effect Sensor - AH1815 (Non-Latching)
    Rating:
    93% of 100
    SKU: SEN-14709 Brand: Sparkfun
    The AH1815 is an integrated Hall-Effect non-latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle...

  6. Hall Effect Sensor - US1881
    Rating:
    100% of 100
    SKU: COM-09312 Brand: Sparkfun
    The US1881 is an integrated Hall effect latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A hall effect sensor is much smaller, but can handle less current than a reed switch.

  8. Reed Switch
    Rating:
    100% of 100
    SKU: COM-08642 Brand: Sparkfun
    This is a small device called a reed switch. When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is removed, the reeds separate and the switch opens. This makes for a great non-contact switch. This switch can carry up to 1.2A.
