A3144 OH3144 Y3144 3144 Hall Effect Sensor Magnetic Detector 4.5-24V

A3144/ OH3144/ Y3144 3144 Hall Effect Sensor Magnetic Detector 4.5-24V TO-92 A3144 OH3144 AH3144E TO-92U Hall Effect Sensor for Arduino Description: A3144 Hall Sensor The A3144E(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 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 http://www.instructables.com/id/Hall-Effect-Magnetic-Pole-Identifier/?ALLSTEPS Vedio Tutorial: https://www.youtube.com/watch?v=wpAA3qeOYiI
