KY-024 Linear Hall Magnetic Sensor 

KY-024 Linear Hall Magnetic Sensor

The KY-024 Linear Hall Magnetic Sensor is a compact and versatile module designed for detecting magnetic fields in electronic applications. It employs a 49E linear Hall effect sensor to provide an analog output that varies linearly with the strength and polarity of the magnetic field. Additionally, the module features an LM393 dual differential comparator that generates a digital output when the magnetic field exceeds a user-defined threshold, adjustable via an onboard potentiometer. This dual-output functionality, combined with its compatibility with microcontrollers like Arduino and Raspberry Pi, makes the KY-024 ideal for applications ranging from simple magnetic switches to complex position and speed sensing systems.
