3144E Hall Sensor Magnetic Sensor Module

The 3144E Hall Effect Magnetic Sensor Module is a compact magnetic field detection module based on the 3144E unipolar Hall-effect sensor IC. It is designed to detect the presence of a magnetic field from a permanent magnet without physical contact. When a magnetic field of sufficient strength is detected, the module provides a digital output signal. It operates on a 3.3V to 5V DC supply, making it compatible with popular microcontrollers such as Arduino, ESP8266, ESP32, Raspberry Pi, and other embedded systems. The module is built on an MH-Sensor-Series PCB and includes a standard pin interface for easy integration.
