KY-035 Hall Magnetic Sensor Module – Product Description

The KY-035 Hall Magnetic Sensor Module is a linear Hall-effect sensor designed to detect and measure the strength and polarity of magnetic fields. It is based on the AH49E Hall-effect sensor, which produces an analog voltage output proportional to the magnetic field intensity. When no magnetic field is present, the output voltage remains approximately half of the supply voltage. As the magnetic field changes, the output voltage increases or decreases depending on the magnet's polarity.

Operating on 3.3V to 5V DC, the KY-035 is fully compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontroller platforms. Its analog output enables accurate magnetic field measurement, making it suitable for position sensing, speed detection, motor control, and automation applications.

The KY-035 Hall Magnetic Sensor Module provides a reliable and cost-effective solution for measuring magnetic fields with high precision. Its analog output and simple interface make it an excellent choice for embedded systems, robotics, automation, and educational projects that require accurate magnetic field sensing.

FAQ

Will this ship from Manila?

Yes — all stock ships from our Quezon City warehouse. Order before 4 PM weekdays for same-day cutoff via J&T or LBC.

Do you ship nationwide?

Yes. Metro Manila usually arrives next-day; provincial 1–3 working days.

Can I get this on a school PO or class order?

Yes — we accept Purchase Orders from accredited schools and universities. Contact us with your PO details and we'll process it.

Is this compatible with Arduino, ESP32, or Raspberry Pi?

Most parts work with common maker boards — check the description for specific pinout / voltage notes. If you're unsure, send us a message before ordering.

What's your return policy?

7-day inspection window for DOA units. Email proof of issue and we'll ship a replacement or refund. Used / installed parts are not returnable unless faulty.

Do you offer technical support?

Yes — questions land on our forum or via email, weekday or weekend. We've actually wired up most of what we sell.
