If you want to replicate the YL-105 function on a custom PCB, here is the minimal bill of materials: yl-105 datasheet
And the datasheet added one final line: “You have 12 picofarads to decide if you want the truth—or your body back.”
Most YL-105 modules come with a 4-pin header: Arduino and NRF24L01 : 6 Steps (with Pictures)
The designation typically refers to an Infrared PIR Motion Sensor Alarm or a specific Mechanical Seal . Below are the datasheet details for both versions. 1. Infrared Motion Sensor Alarm (YL-105)

The is a highly efficient voltage regulator and socket breakout board explicitly engineered to power and interface the popular nRF24L01+ 2.4GHz wireless transceiver module . While the nRF24L01+ requires a strict 1.9V to 3.6V power source, standard microcontrollers like the Arduino UNO deliver 5V logic and power. Attempting to power an nRF24L01+ module directly from an unregulated 5V rail can instantly fry the chip, while utilizing the Arduino's on-board 3.3V pin frequently causes connection drops due to inadequate current supply. The YL-105 socket board addresses this hardware bottleneck by incorporating an on-board AMS1117 3.3V step-down linear regulator and local decoupling capacitors to provide a clean, dedicated power stream.
: Raw DC power (5V–12V) feeds into the VIN node of the AMS1117-3.3 linear regulator. This steps the input down to a smooth, constant 3.3V DC rail.
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.
Read the AO pin with an ADC. The analog voltage will change as a magnet moves parallel to the sensor face. Calibrate the ADC reading to distance. This is not a high-precision linear encoder, but it works for coarse position feedback (e.g., throttle position, linear actuator feedback).
