The Analog Hall Magnetic Sensors are based on the 3144 Series Hall Effect switch IC, utilizing advanced magnetic semiconductor integration technology. These sensors combine various components, including a voltage regulator, Hall voltage generator, differential amplifier, Schmitt trigger, temperature compensation circuit, and an open-circuit output stage to form the magnetic sensing circuit. The sensor detects magnetic flux density at the input and outputs a digital voltage signal.

This module features both analog magnetic sensing and a digital interface, along with a built-in 13-LED setup, which allows for the creation of a simple circuit to generate magnetic pulses or flashes.
