KY-024 Linear Magnetic Hall Sensor

Description:

The KY-024 Linear Magnetic Hall Sensor Module is a versatile and compact solution for detecting and measuring magnetic fields in your electronics projects. This module utilizes a 49E linear Hall effect sensor to provide a highly accurate and responsive output, making it ideal for a wide range of applications from simple magnetic switching to precise position and speed sensing.

A key feature of the KY-024 is its dual output capability: it provides both an analog output (A0) that delivers a voltage proportional to the strength and polarity of the magnetic field, and a digital output (D0) that acts as a switch, triggering when the magnetic field exceeds a user-defined threshold. This digital threshold is easily adjustable via an onboard potentiometer (trimmer), allowing you to fine-tune the sensor's sensitivity to your specific application.

Equipped with an LM393 dual differential comparator and indicator LEDs, the KY-024 is straightforward to interface with popular microcontrollers like Arduino, ESP32, Raspberry Pi, and other development boards. Its robust design and clear pinout make it a reliable choice for educational purposes, DIY projects, and industrial automation.
