Yl-105 Datasheet -

Look at the YL-105 module (if you have it). Find the main chip on the PCB. It will likely be one of these:

Write down the number on the largest IC. That is the real part you need a datasheet for.

This means for every 100 Gauss increase in magnetic field, the analog output rises by 250mV.

If you’ve been searching for “YL-105 datasheet” , you’re likely working on a robotics or electronics project involving obstacle avoidance or line sensing. The YL-105 is a popular, low-cost infrared (IR) sensor module often sold alongside Arduino starter kits.

However, there’s a common frustration: the YL-105 is a clone of the more widely documented TCRT5000 sensor module. You will rarely find an official datasheet labeled “YL-105,” but don’t worry—by understanding the hardware, you can use the TCRT5000 datasheet as your go-to reference.

Here is everything you need to know, pulled from the technical specifications of its underlying components.

| Problem | Likely Cause | Solution | |---------|--------------|----------| | Output always LOW | Threshold too low or magnet always present | Turn potentiometer clockwise to increase threshold | | Output always HIGH | Threshold too high or no power | Turn potentiometer counterclockwise, check VCC/GND | | Jittery output near switching point | No hysteresis | Add a 100k resistor from DO to non-inverting input, or use software debounce | | No response even with strong magnet | Wrong magnetic pole | Use south pole of magnet | | AO reads constant voltage | Hall sensor damaged or VCC unstable | Check VCC with oscilloscope; replace module if needed |

This hypothetical datasheet outlines general and specific information that a manufacturer might provide for a component like the YL-105. Actual specifications would depend on the product's intended application, design, and compliance with various regulatory standards.

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)

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: Look at the YL-105 module (if you have it)

“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 commonly identified as an Infrared (IR) Obstacle Avoidance Sensor Module designed for basic object detection and proximity sensing in robotics and automation. It operates on the principle of reflecting infrared light off a surface to detect its presence. Key Technical Specifications Operating Voltage: 3.3V to 5V DC.

Sensing Range: Typically 2 cm to 30 cm (adjustable via onboard potentiometer). Detection Angle: Approximately 35°. Operating Current:

Output Type: Digital TTL signal (0 or 1). Usually, it outputs Low (0V) when an obstacle is detected and High (VCC) when the path is clear.

Comparator Chip: Often utilizes the LM393 voltage comparator for stable signal output. Module Interface (Pinout) The module typically features a 3-pin or 4-pin header: VCC: Power supply input (3.3V–5V). GND: Ground connection. OUT: Digital output signal.

EN (Optional): Enable pin; the sensor is active when this pin is Low and disabled when High. Visual Indicators & Adjustments IR Obstacle Avoidance Sensor Module - SunFounder

The YL-105 (also known as the AMS1117-3.3 Adapter) is a power regulator module specifically designed to simplify the connection of nRF24L01+ wireless transceivers to microcontrollers like Arduino. Core Purpose

The primary challenge with the nRF24L01 module is its strict 3.3V power requirement, while most standard Arduinos operate at 5V. Connecting a wireless module directly to a 5V pin can permanently damage it. The YL-105 Adapter bridges this gap by converting a 5V input into a stable 3.3V output for the radio. Key Specifications Onboard Regulator: Integrated AMS1117 3.3V chip.

Input Voltage: DC 4.8V to 12V (typically powered via the Arduino 5V pin). Output Voltage: Fixed 3.3V.

Interface: 8-pin socket for direct plug-and-play with the nRF24L01+ module.

Output Current: Capable of providing up to 800mA, which is more than sufficient for both standard and high-power (PA+LNA) versions of the radio. Wiring & Pinout

The adapter features a 2-pin header for power input and a standard SPI header for data: VCC: Connect to 5V on your microcontroller. GND: Connect to GND on your microcontroller.

SPI Pins (CE, CSN, SCK, MOSI, MISO, IRQ): These pass directly through to the nRF24L01. Why Use It?

Voltage Stability: Common Arduino 3.3V pins often lack the peak current capacity needed during radio transmission, leading to communication failures. The YL-105 provides much cleaner and more robust power.

Breadboard Friendly: It breaks out the double-row pins of the nRF24L01 into a format that is easier to wire with standard jumper cables.

Troubleshooting: If your YL-105 indicator LED is off when power is applied, it likely indicates a short circuit or a faulty regulator.

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 Write down the number on the largest IC

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.
