⚡ KY-003 Hall Magnetic Sensor Module ⚡
The KY-003 module uses a Hall Effect sensor to detect magnetic fields. When a magnet is brought close to the sensor, the digital output switches state (HIGH/LOW), making it ideal for motion detection, speed measurement, and position tracking. With its simplicity and easy integration into Arduino and Raspberry Pi projects, it is widely used in educational and robotics applications.
