A hall effect sensor is much smaller but can handle less current than a reed switch.
A3114 hall sensor.
The device includes an on chip hall voltage generator for magnetic sensing a comparator that amplifies the hall voltage and a.
A3144 is a digital output hall sensor meaning if it detects a magnet the output will go low else the output will remain high.
This hall effect sensor module consists of a hall sensor resistors capacitor potentiometer comparator lm393 ic power and status led in an integrated circuit.

Second one is the ground pin and is used for supplying ground to this sensor.
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.
