A3144 is a digital output hall sensor meaning if it detects a magnet the output will go low else the output will remain high.
A3114 hall sensor.
It is also mandatory to use a pull up resistor as shown below to keep the output high when no magnet is detected.

This hall effect sensor module consists of a hall sensor resistors capacitor potentiometer comparator lm393 ic power and status led in an integrated circuit.
From these pins first pin is power pin and is used for power on this sensor.
These sensors that latch on to a particular state are called latched hall effect sensors.
The hall effect in short is a relationship between electric and magnetic fields through a semiconductor.

5v dc voltages are used for power on this sensor.
A3144 is a digital output hall sensor meaning if it detects a magnet the output will go low else the output will remain high.
The sensor gives an output high voltage whenever the north pole of a magnet is brought close to it and switches low whenever the magnet is removed.
