Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →The KY-035 Hall Magnetic Sensor is a compact electronic module designed to detect the presence and changes of a magnetic field. It uses a Hall-effect sensor to respond to magnetic fields, allowing a microcontroller to monitor magnetic movement or proximity.
The module provides a simple interface that makes it easy to connect to Arduino and other microcontroller-based systems. When a magnet is brought near the sensor, the sensor detects the change in the magnetic field and produces a corresponding electrical signal.
Its compact size and straightforward operation make the KY-035 suitable for educational projects, robotics, automation, and electronic systems that require magnetic detection.
Key Features:
Hall-effect magnetic field sensor
Detects nearby magnetic fields
Compact and lightweight module
Simple interface for microcontrollers
Compatible with Arduino and other development boards
Easy to integrate into breadboard projects
Suitable for magnetic proximity detection
Designed for DIY and educational electronics
Common Applications:
The KY-035 can be used for magnetic proximity detection, object position sensing, rotation detection, door or switch monitoring, robotics, automation projects, Arduino experiments, and other applications requiring magnetic field detection.
