Yl105 Datasheet Better [updated] Jun 2026

The YL-105 datasheet ignores cable capacitance. If your cable to the sensor exceeds 30cm, readings drop by 10%.

Scour any YL-105 datasheet, and you will see a proud block diagram showing the PC817 optocoupler straddling the "input" and "output" sides. The implication? Galvanic isolation. This is the most dangerous half-truth in the documentation.

makes your system better, you must look at the constraints of the nRF24L01 chip datasheet:

: The nRF24L01 module operates at 3.3V, but many microcontrollers like the Arduino Uno supply 5V on their pins. Connecting a 5V power source directly to the nRF24L01 can damage it. The YL-105 adapter integrates a 3.3V regulator (typically an AMS1117 ) to provide the correct voltage. yl105 datasheet better

Here are the specs you actually need for your design calculations:

However, if you’ve tried looking for a standard "YL-105 datasheet," you know the struggle: documentation is often sparse, written in broken English, or simply non-existent. Many users confuse it with similar modules like the HC-11 or HC-12.

A full manual (10 pages) is available from Yi Lin, covering settings, connections, and technical data. The YL-105 datasheet ignores cable capacitance

Once you turn on the main unit, the green LED lights for of warm‑up. This gives you time to leave the protected area without triggering the alarm. After the green light turns off, any human movement within the detection zone triggers the red LED and, after a 5‑second delay , the 105 dB siren sounds for 45‑50 seconds (some versions: 30 seconds). After the siren stops, the unit automatically re‑arms itself. You can turn off the alarm at any time with the remote control; an intruder cannot silence the alarm.

: Integrated AMS1117-3.3 chip for low-dropout regulation.

: Wireless modules are sensitive to EMI. The onboard bypass capacitors on the YL105 serve as a "better" solution than manual wiring with loose electrolytic capacitors. The implication

When engineers search for a "better" datasheet, they are looking for comprehensive technical data, operational limitations, and clear installation guidance. The SRWQ100-YL105-9001 datasheet provides exactly that. Here is what makes it superior: 1. Robust Technical Specifications

: 5.0V DC (compatible with 51 microcontroller and Arduino systems). Output Voltage : Stable 1.9V to 3.6V DC (typically 3.3V). Operating Current : Approximately 12.3 mA.

The YL series is known for its high starting torque, generally around 1.8 to 2.2 times the rated torque. However, the YL105, owing to its larger motor frame, maintains this high torque across a broader operational spectrum. For high-inertia loads like compressors, the YL105 ensures smooth startup under load. B. Superior Power-to-Size Ratio
