Hall-Effect Sensor - US1881 (Latching) Heat Shrink (4mm - 25cm) Infrared wave length: 8~15umThe 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. The device includes an on chip Hall voltage generator for magnetic sensing, a
