Frequently Asked Questions

Q: What does the KY-003 Hall Effect Sensor Module detect?

A: The KY-003 module uses the A3144 Hall Effect IC to detect the presence and polarity of magnetic fields. When a magnet comes near the sensor, the module outputs a digital LOW signal; when no magnetic field is present, it outputs HIGH. This makes it ideal for proximity sensing, position detection, RPM measurement, and magnetic switch applications in Arduino or other microcontroller projects.

Q: Is the KY-003 Hall Effect Sensor Module compatible with Arduino boards?

A: Yes — the KY-003 is fully compatible with all popular Arduino boards including the Uno, Nano, and Mega, as well as Raspberry Pi and other 5V microcontrollers. It uses a simple 3-pin interface (VCC, GND, Signal) that connects directly to standard digital input pins with no additional components required.

Q: What voltage does the KY-003 Hall Effect Sensor Module operate at?

A: The KY-003 module operates at 5V DC, which is the standard logic level for Arduino boards. It provides a clean digital output signal, making integration into your projects straightforward and reliable.

Q: Can the KY-003 detect both weak and strong magnetic fields?

A: Yes. The A3144 Hall Effect IC at the heart of the KY-003 module is capable of detecting a wide range of magnetic field strengths, from relatively weak fields to stronger ones. For best results, use a standard neodymium or ferrite magnet within close proximity of the sensor face.
