Yl-105 Datasheet
The YL-105 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)
- Digital Output (DO): Compares the sensor’s analog voltage to the potentiometer’s threshold. It outputs
0(LOW) if reflection is above the threshold, else1(HIGH). - Analog Output (AO): This pin bypasses the comparator. The voltage drops as more IR light is reflected back. Use this with an ADC pin for precise distance or color sensing.
This module is a breakout board designed to simplify the use of the 8-pin nRF24L01 wireless transceiver with microcontrollers like Arduino. yl-105 datasheet

Safety and Usage Tips
- ESD Sensitivity: The 49E Hall sensor is sensitive to electrostatic discharge. Ground yourself before handling.
- Magnet Placement: Keep magnets away from other sensitive electronics (HDDs, credit cards, pacemakers).
- Temperature Effects: The 49E’s quiescent voltage drifts slightly with temperature. For precision work, recalibrate the potentiometer after thermal changes.
- Power Supply: Use a regulated 5V supply. Ripple above 100mV can cause false triggering.

Since no official datasheet exists for "YL-105" as a unique component, your best document is the datasheet for the main IC + a generic schematic for that module type. Digital Output (DO): Compares the sensor’s analog voltage
