The KY-24 Hall Effect Sensor Module is a small and versatile linear Hall Effect sensor that is actuated by a magnetic field through a permanent magnet or an electromagnetic field. The output voltage is regulated by the power supply voltage and varies in proportion to the strength of the magnetic field. Its integrated circuit output has low noise, eliminating the need for unnecessary external filters. It also includes precision resistors to increase temperature stability and accuracy. The operating temperature range of these linear Hall sensors is -40 to 85 degrees Celsius, suitable for commercial and industrial applications.

This module has a Hall effect sensor for magnetic field detection and also has analog (AO) and digital (DO) outputs. It has a potentiometer to adjust the sensor sensitivity and a built-in microcontroller for signal processing

It can be connected to Arduino, ESP32, STM32 and other microcontroller boards.

VCC: Power supply (usually 3.3V or 5V)

GND: Ground

AO (Analog Output): Analog output proportional to the magnetic field strength
