SparkFun Hall Effect Sensor - US1881 Magneto Plus-Size Stand-alone operation: No microcontroller neededThe US1881 is an integrated Hall effect latched sensor. Thats 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
