IR Beam Interruption Sensor - LED 3mm - 0-50 cm

The sensor reacts to an interruption in the beam of infrared light that is transmitted between the transmitter and receiver. When the beam is interrupted by another object, the receiver signals this event by lighting up. The module is equipped with a 3 mm IR LED with an illumination angle of 10°. Beam interruption systems are used e.g. in measuring gates.

Hall-Effect Sensor - US1881 (Latching)

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...
