Yl-105 Datasheet __hot__ May 2026

The YL-105 datasheet likely refers to a specific model of a lithium-ion battery or a related component, given the naming conventions often used in electronics and battery manufacturing. Without a direct reference to a widely known component, I'll create a hypothetical datasheet feature for a product named "YL-105," assuming it's a lithium-ion battery designed for various portable electronic applications. Here are some features that might be included:

Example 1: RPM Measurement (Tachometer)

Connect DO to an Arduino digital pin with a pull-up resistor enabled (or use INPUT_PULLUP). Place a small neodymium magnet on a rotating shaft. Each time the magnet passes the YL-105, the output goes LOW. Use interrupts to count pulses per minute.

Arduino Code Snippet:

int sensorPin = 2;
volatile int pulseCount = 0;

void setup() 
pinMode(sensorPin, INPUT_PULLUP);
attachInterrupt(digitalPinToInterrupt(sensorPin), countPulse, FALLING);
Serial.begin(9600);



void loop() 
// Calculate RPM every second
// ...

Usage and Precautions

  • Recommended Charge/Discharge Rate: 0.2C to 1C
  • Handling Precautions: Avoid short circuits, do not bend or crush

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 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)

This is a common wireless security device used to detect motion and trigger a loud siren for home or commercial security. Specification Detection Technology PIR (Passive Infrared) Siren Volume Detection Range Approx. 5 meters Detection Angle 110 degrees wide Alarm Unit Power 4 x AA batteries Remote Power 3 x AG13 button cells Standby Current Alarm Current Material ABS plastic (White) Key Features:

Loud Alert: Emits a piercing 105dB alarm to deter intruders.

Wireless Operation: Ideal for garages, sheds, and shops without complex wiring. yl-105 datasheet

PIR Motion Tracking: Triggers only when heat signatures (like a person) move through its field of view. 2. YL-105 Mechanical Seal

In industrial contexts, the YL-105 is a standard mechanical seal used for pumps.

Structure: Single end, multiple springs, and unbalanced design. Specifications: Inner diameter ranges from 35 mm to 180 mm. Pressure Rating: Designed for low-pressure environments.

Standard Compliance: Follows the JB/T1472-94 industrial standard.

Applications: Used in chemical centrifugal pumps, screw pumps, and sewage treatment equipment across industries like oil refining and pharmaceuticals. Related Modules often confused with YL-105 The YL-105 datasheet likely refers to a specific

YL-17 / YL-105 Socket Adapter: A breakout board for nRF24L01 wireless modules that includes a 3.3V voltage regulator.

YL-69: A widely used soil moisture sensor often found in similar DIY electronics listings. YL 105 - YALAN Seals - China Mechanical Seal Standard Maker

Pinout Configuration

Most YL-105 modules come with a 4-pin header:

  1. VCC – Power (3.3V – 5V)
  2. GND – Ground
  3. DO – Digital Output (HIGH/LOW based on threshold)
  4. AO – Analog Output (Direct voltage from phototransistor)

Note: Some budget clones swap the pin order. Always check the back of your PCB for labels.
