Hall sensor module A3144

This A3144 module is a board with a built-in Hall sensor, which is designed to detect the magnetic field. Hall sensor A3144 can be used as motor rotation controller, switch, encoder, etc. It can also be used in the Levitron as a sensor that determines the distance between the magnet and the inductance.

The module board is designed based on the A3144 sensor, voltage regulator, Schmitt trigger and other auxiliary components, which ensure the correct operation of the module. The Hall sensor is a sensor that operates on the Hall effect (potential difference when a DC conductor is placed in a magnetic field). The output of the sensor can be in 2 states (HIGH, LOW), which determine the magnetic field. When a magnetic field is applied to the sensor, the transistor opens and a low signal level (LOW) appears at its output, respectively, in the absence of a magnetic field at the output of the Hall sensor, the logical signal HIGH.

The module is connected to the Arduino platform or other microcontroller devices using 3 pins. Sensor board pin assignments:

VCC: supply voltage 5V
GND: ground
A0: analog signal (output voltage depends on the distance to the source of the magnetic field)
D0: digital signal

There are 2 LEDs on the module board:

LED1: lights up when power is supplied to the module
LED2: lights up when a signal is transmitted

The module is powered by an external power source, Arduino platform or other microcontroller device.
