Yl-105 Datasheet ✪ [ TESTED ]

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.

The module has an onboard potentiometer (blue box). This adjusts the reference voltage for the LM393 comparator.

Common calibration: Place the sensor 5mm above a white surface. Turn the potentiometer until the onboard LED just turns off. Now, the module will trigger reliably when seeing white vs. black.

If you need a reliable receipt of signals from standard wireless remotes or sensors, the YL-105 is the superior choice over the cheaper "green board" receivers.

(General Purpose) FIT-300 (Dual Wall/Adhesive) Cross-linked Polyolefin Cross-linked Polyolefin with Adhesive Shrink Ratio Shrink Ratio Operating Temp -55°C to +135°C Operating Temp -55°C to +125°C Shrink Temp 90°C (minimum) Shrink Temp 110°C (minimum) Voltage Rating Voltage Rating Flame Retardancy UL 224 VW-1 (for 'V' models) Flame Retardancy Self-extinguishing 3. 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.

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.

Connect DO to a microcontroller input. Set the threshold so the output is LOW only when a magnet is within 5mm. Mount the magnet on a door and the sensor on the frame. When the door opens, the magnet moves away, and the output goes HIGH, triggering an alarm.

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.

Here’s what to do:

The LM393 does not have built-in hysteresis, but many YL-105 modules add a small positive feedback resistor. Check your board; if not present, you may experience output jitter near the threshold. The datasheet often omits this, so add hysteresis in software (debouncing) or external resistors if needed.

Because the YL-105 acts like a digital switch, wiring is simple.

Wiring:

Arduino Sketch:

const int sensorPin = 7;  // Digital input
const int ledPin = 13;     // Built-in LED
void setup() 
pinMode(sensorPin, INPUT);
pinMode(ledPin, OUTPUT);
Serial.begin(9600);

void loop() 
int sensorState = digitalRead(sensorPin);
if (sensorState == LOW)   // Object or white surface detected
digitalWrite(ledPin, HIGH);
Serial.println("Detected!");
 else 
digitalWrite(ledPin, LOW);
Serial.println("Clear");
delay(100);
