Yl-105 Datasheet Jun 2026

Whether you are building a simple non-contact switch or an advanced magnetic field logger, the YL-105 delivers reliable performance. Always refer to the component-level datasheets for electrical characteristics, and use the module’s potentiometer to dial in the perfect detection range for your application.

: Always choose a diameter where the recovered (shrunk) ID is smaller than the diameter of the substrate you are covering to ensure a snug fit. : If using the FIT-300 (F300) yl-105 datasheet

For the module to work effectively, you must attach an antenna. Whether you are building a simple non-contact switch

Note: In some niche electronic contexts, "YL-105" may also refer to an 8-pin adapter board specifically designed for the radio module to simplify wiring and power regulation. Infrared Motion Sensor Alarm YL-105 Instruction Manual : If using the FIT-300 (F300) For the

Connect DO to an Arduino digital pin with a pull-up resistor enabled (or use INPUT_PULLUP ). Place a small neodymium magnet on a rotating shaft. Each time the magnet passes the YL-105, the output goes LOW. Use interrupts to count pulses per minute.
