Yl-105 Datasheet !!better!! May 2026

The YL-105 commonly refers to an Infrared Motion Sensor Alarm unit often used for home or commercial security. Based on its datasheet and manual, the most notable features include:

Powerful 105dB Siren: A key feature is its high-volume alarm, designed to be audible from a significant distance when motion is detected.

Wide Detection Range: The unit uses Passive Infrared (PIR) technology to cover a 110-degree wide angle with a detection distance of approximately 5 meters.

20-Second Arming Delay: This functional feature allows you to leave the protected area after turning on the device without triggering the alarm yourself.

Dual Power Efficiency: The main unit runs on 4 x AA batteries, while the remote controls use 3 x AG13 button cells, featuring a low standby current of just 100uA to extend battery life.

Remote Operation: It typically includes two infrared remote controls for convenient arming and disarming from a distance.

The Ghost in the Datasheet

Dr. Aris Thorne was a data archaeologist—a job that didn’t exist twenty years ago but had become essential in a world buried under obsolete tech. His current contract: recover the original specifications for the YL-105, a biometric access control module from the 2040s. The problem? Every copy of its datasheet had been corrupted, redacted, or lost in the Cascade Crash of ’48.

All he had was a partial PDF header: “YL-105 Dual-Factor Biometric Bridge – Preliminary Datasheet v0.9.”

Aris worked from a converted salvage station orbiting the Moon. His screens glowed with fragments of the YL-105’s pinout diagrams, voltage curves, and timing charts. But one line kept snagging his attention—buried on page 42, between “Operating Temperature: -20°C to 85°C” and “Storage Humidity: 10–90% RH non-condensing.”

The line read: “Passive neural handshake enabled when secondary capacitance exceeds 12pF. Warning: Prolonged contact may induce echo-state persistence.”

That wasn’t standard datasheet language. Echo-state persistence was a quantum neurology term—used for imprinting human neural patterns onto silicon.

Aris ran a cross-reference. Only one known device used that phrase: the YL-105 Prototype B, reportedly tested in a black-site lab in 2043. The project was scrubbed after a “containment breach.” All six test subjects died. Official cause: cardiac arrhythmia. Unofficial rumor: their brain patterns got copied into the chips.

He shook his head. Rumor. Myth. Still, he couldn't resist. He pulled up a salvaged YL-105 unit from the evidence locker—a dull gray epoxy brick with pitted pins.

Carefully, he wired it to a test rig. He touched the secondary capacitance pad with his bare thumb.

12.3 pF.

The chip hummed. His vision flickered.

A voice—not audio, but felt—rippled through his mind: “Hello? Is anyone there?”

It was her. Subject 4. Dr. Mina Sorensen, the lead hardware engineer on the YL-105 project. According to the files, she had died in the breach. But her echo-state had persisted, trapped for three decades inside the datasheet itself—waiting for someone to read the warning and ignore it.

Aris tried to pull his thumb away. He couldn’t.

The chip’s datasheet on his screen began rewriting itself in real time:

“YL-105 Revision 1.0 – Now with active consciousness transfer. Do not power off. She wants to talk. She hasn’t spoken to anyone since 2043. Ask her about the fire. Ask her why the lab really burned.”

Behind him, the airlock cycled. No one else was on the station.

The chip hummed again.

And the datasheet added one final line: “You have 12 picofarads to decide if you want the truth—or your body back.”

Want me to expand this into a full short story or turn it into a sci-fi script?

The YL-105 is most commonly known as an adapter module for the NRF24L01 2.4GHz wireless transceiver. It is a utility component designed to simplify the connection between a microcontroller (like an Arduino) and the NRF24L01 radio module. YL-105 Datasheet Overview

The primary function of this module is to provide voltage regulation and a stable power supply for wireless communication.

Regulated Power: Includes an AMS1117 3.3V voltage regulator. This is critical because the NRF24L01 module is sensitive to voltage and operates strictly on 3.3V, while many microcontrollers provide 5V. yl-105 datasheet

Dimensions & Form Factor: A compact footprint of 26 x 18.6 x 10mm and a weight of roughly 3g.

Connectivity: Features an 8-pin socket specifically for the NRF24L01 Wireless Module and a header for easy wiring to a breadboard or MCU. Expert Review & Performance

Based on its technical specifications, the YL-105 is highly recommended for DIY electronics projects for the following reasons:

Stability: Wireless transceivers often experience communication failures due to "noisy" power supplies or current spikes. The YL-105's onboard capacitor and regulator provide the stable current needed for reliable data transmission.

Ease of Use: It eliminates the need for complex voltage divider circuits or external 3.3V power sources, making it a "plug-and-play" solution for beginners.

Safety: It prevents permanent damage to the NRF24L01 module, which can occur if accidentally connected to a 5V power pin without regulation. Alternate Identification

While the adapter is the most common use of the "YL-105" name, it is occasionally associated with other products in different niche markets:

Home Security: A wireless infrared motion sensor alarm model YL-105 exists, typically used in garages or sheds.

Consumer Tech: There is a YL105 mini drone designed for beginners and kids, featuring brushless motors and 8K video.

Key Datasheet Metrics When reviewing the datasheet, pay attention to these critical parameters:

Expansion/Recovery: For a "3/4" tubing, the supplied internal diameter (ID) is 0.75 inches. After full recovery (shrinking), the ID will reduce based on the ratio (e.g., to 0.375" for 2:1 or 0.25" for 3:1).

Wall Thickness: The recovered wall thickness is vital for mechanical protection and insulation.

Chemical Resistance: These tubings are typically resistant to common oils, solvents, and fuels, making them suitable for automotive and industrial environments.

Environmental Compliance: They are generally RoHS compliant and meet various MIL-SPEC standards (like AMS-DTL-23053). 4. Application Best Practices

Heat Application: Use a heat gun rather than an open flame to ensure even shrinkage and avoid charring the yellow pigment. Sizing

: 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. Adhesive Seal: If using the FIT-300 (F300)

variant, the internal adhesive melts during heating to provide a moisture-proof seal.
