Características
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.
The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.
If a magnetic flux density larger than threshold Bop, DO is turned on (low). The output state is held until a magnetic flux density reversal falls below Brp causing DO to be turned off (high).
Features:
- 3.5V to 24V DC operation voltage
- Low current consumption
- Temperature compensation
- Wide operating voltage range
- Open-Collector pre-driver
- 50mA maximum sinking output current
- Reverse polarity protection
- Lead Free Package: TO-92

Hola Daniel, este sensor tiene una salida fija en función de la polaridad magnética que detecte. Si acercas un polo norte, su salida será baja, y cuando acerques un sur, alta. Mas específicamente, su salida funciona como colector abierto. Saludos!

con este sensor se puede hacer como un potenciometro acercando y alejando un iman? tenes imanes.
