상품 특징

• This magnetic sensor module uses a reed switch element to detect the presence of a magnetic field. When a magnet approaches the sensing area, the internal reed contacts change state, allowing the module to output a corresponding digital signal for control logic applications.
• Configured as a normally closed type, the output signal changes when magnetic flux is detected. This configuration supports state monitoring applications where default closed-circuit logic is required in embedded systems and microcontroller-based projects.
• Operates within a 3.3V to 5V DC voltage range, enabling direct connection to common development boards without additional level shifting components. The digital output can be read directly by GPIO input pins.
• Compact PCB design with clearly labeled VCC, GND, and DO pins simplifies wiring and installation. The board format supports breadboard use and integration into prototype circuits and custom enclosures.
• Suitable for position sensing, door state detection, motion limit indication, and magnet-triggered control logic in educational electronics projects and embedded development systems.
