Short Description
The KY-003 Hall Effect Magnetic Sensor Module is a tiny digital magnetic switch that detects the presence of a magnetic field.
It employs an A3144 Hall-effect sensor and outputs a digital signal that changes state when a suitable magnetic field is detected.
When the sensor is activated, an inbuilt LED illuminates.
The module is ideal for Arduino, robotics, position sensing, speed detection, and automation applications.
