49E Hall Effect Sensor Module

The KY-24 Hall Effect Sensor Module is a compact and versatile Linear Hall Effect Sensor Module that is activated by a magnetic field from a permanent magnet or an electromagnetic source. Its output voltage is regulated by the supply voltage and varies according to the strength of the magnetic field. The integrated circuit provides low-noise output, eliminating the need for additional external filters. Precise resistors within the module enhance temperature stability and measurement accuracy. The operating temperature range of these linear Hall sensors is -40 to 85°C, making them suitable for both commercial and industrial applications.

This Hall Effect Sensor Module features both analog (AO) and digital (DO) outputs. It includes a potentiometer to adjust sensor sensitivity and a built-in microcontroller for signal processing. The module is compatible with Arduino, ESP32, STM32, and other microcontroller boards.

Module Pins:

• VCC: Power supply (typically 3.3V or 5V)
• GND: Ground
• AO (Analog Output): Analog signal proportional to the magnetic field strength
• DO (Digital Output): Digital signal that changes state when the magnetic field exceeds a set threshold (adjustable)

This KY-24 Hall Effect Sensor Module offers a reliable, compact solution for detecting magnetic fields, providing both high precision and ease of integration for various electronic projects.
