KY-003 A3144 Hall Effect Sensor Module for Arduino

Add contactless magnetic detection to an Arduino or compatible electronics project with the KY-003 A3144 Hall effect module. Its digital output can support position, speed, proximity and switching experiments.

Add magnetic detection to a DIY circuit

• ✅ Use a magnet to trigger a sensor input without a mechanical switch.
• ✅ Explore magnetic sensing in an Arduino-compatible prototype.
• ✅ Integrate the A3144 Hall switch and open-collector output into a suitable circuit.

Confirm the target board's logic and wiring requirements before connecting the module.

Add this Hall effect sensor to a compatible Arduino build and plan the input circuit.
