In the world of embedded systems, robotics, and industrial automation, few components are as useful yet as underappreciated as the Hall effect sensor. Among the myriad of options available, the stands out as a popular, reliable, and cost-effective solution for non-contact magnetic switching. Whether you are a hobbyist building a tachometer for a DIY fan, a student working on a security system, or an engineer prototyping a position sensor, finding the official YL-105 datasheet is your first critical step.
The YL-105 serves as a power management and socket adapter for the nRF24L01+ wireless module. Its primary purpose is to provide voltage regulation noise filtering
Designed for low-pressure environments and general temperature ranges. Size Range: Available in inner diameters ranging from 35 mm to 180 mm YALAN Seals Primary Applications yl-105 datasheet
The AO pin is rarely used in simple digital applications. It provides a voltage between 0V and VCC proportional to the magnetic field strength, useful for linear position sensing or magnetic field strength measurement.

: The unit uses Passive Infrared (PIR) technology to cover a 110-degree wide angle with a detection distance of approximately 5 meters . The YL-105 serves as a power management and
Use the digital output to trigger a relay for a humidifier or dehumidifier.
: This indicates that the microcontroller cannot establish an SPI connection with the nRF24L01+ chip. Ensure that the module is firmly pressed into the YL-105's 8-pin socket, and double-check your SPI pins ( Pins 11, 12, 13 on the Arduino Uno).
: A key feature is its high-volume alarm, designed to be audible from a significant distance when motion is detected.
The designation typically refers to one of two different electronic products: an nRF24L01 wireless transceiver adapter or a standalone infrared PIR motion sensor alarm . 1. nRF24L01 Socket Adapter (YL-105)
