Description
KY-003 Hall magnetic sensor module based on the A3144 Hall effect sensor, designed to detect magnetic fields with a digital output signal.
When a magnetic field is present, the module outputs a LOW signal, making it ideal for simple on/off magnetic detection applications.
Compact and easy to use, with built-in components for direct connection to Arduino, ESP32, and other microcontrollers.
Perfect for projects such as door sensors, position detection, speed measurement, and magnetic switches.
