KY-003 Hall Effect A3144E Magnetic Sensor Module for Arduino

KY-003 A3144E Digital Hall Effect Sensor Non-Contact Magnetic Switch Discover the precision of magnetic detection with the KY-003 Hall Effect Sensor Module. At its core is the reliable A3144E Hall sensor IC, designed to detect the presence of a magnetic field. When a magnet is brought near the sensor, it outputs a digital HIGH signal, making it an excellent non-contact switch for your projects. It's incredibly easy to interface with microcontrollers like Arduino, PIC, or AVR. Perfect for students, hobbyists, and anyone building interactive DIY electronics, from simple magnetic alarms to complex RPM counters for motors.
