The output will be latched off in the presence of a resetting north pole magnet.
5v hall effect sensor.
The output transistor will be latched on in the presence of a sufficiently strong south pole magnetic field.
Whenever the hall effect sensor is subjected to a magnetic field it toggles the relay as per the code.

The circuit diagram for controlling a 5v relay module with hall effect sensor and arduino is shown below.
Control a relay with arduino and hall effect sensor.
A hall effect sensor as then name suggests works with the principle of hall effect and is used to detect magnets.
If you are looking for a hall effect sensor be aware that many are digital only output 0 or 5v.
The drv5053 device is a chopper stabilized hall ic that offers a magnetic sensing solution with superior sensitivity stability over temperature and integrated protection features.
If no induction to the magnetic field then the digital output high level the signal light is not bright.
The device is offered in multiple magnetic thresholds sampling rates output drivers and packages to accommodate various applications.
