Project 10 – magnetic change detection

This project leverages the capabilities of the KY-003 sensor, a hall magnetic sensor module. This module is a key component in a variety of electronic projects, particularly those that involve Arduino platforms. The main functionality of the KY-003 sensor is to detect magnetic fields. It has a broad range of applications, from identifying the presence or absence of magnetic objects to measuring the exact position of a magnet. The sensor can also be used to count rotational objects when it is combined with magnets, a feature that is highly beneficial in several industrial and scientific contexts.

The KY-003 module incorporates a Hall effect sensor, a device that operates based on a fascinating principle. It generates a voltage difference across an electrical conductor when a magnetic field is applied perpendicular to the flow of current through the sensor. This voltage difference can be detected by a microcontroller, which is often an...
