Datasheet Updated — Yl-105

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.

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: yl-105 datasheet

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.

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.

Note: In some niche electronic contexts, "YL-105" may also refer to an 8-pin adapter board specifically designed for the nRF24L01 radio module to simplify wiring and power regulation. Infrared Motion Sensor Alarm YL-105 Instruction Manual

The YL-105 designation typically refers to two distinct types of devices in the electronics world: a PIR Motion Sensor Alarm unit and a Transceiver Adapter Module used for wireless communication.

Depending on your project, the "datasheet" you need will cover either an infrared security device or a power stabilization board for nRF24L01 modules. 🏗️ Version 1: YL-105 Transceiver Adapter Module

The YL-105 adapter is a popular breakout board designed to solve power stability issues with nRF24L01+ 2.4GHz wireless modules. Because these radio modules are sensitive to voltage fluctuations, the YL-105 provides a regulated 3.3V supply from a 5V source. Key Specifications Input Voltage 4.8V – 12V DC Output Voltage 3.3V DC (Regulated) Onboard Regulator AMS1117-3.3 Max Current ~800mA (Peak) Pinout Compatibility 8-pin (2x4) nRF24L01 modules Features & Benefits

⚡ Voltage Stabilization: Includes an onboard 3.3V regulator and decoupling capacitors to reduce RF noise.

🛠️ Easy Integration: Bridges the gap between 5V microcontrollers (like Arduino Uno) and 3.3V wireless chips.

📐 Compact Size: Roughly 26mm x 19mm, making it ideal for breadboards or small enclosures. 🛡️ Version 2: YL-105 Infrared Motion Sensor Alarm

In consumer electronics, the YL-105 is a standalone PIR (Passive Infrared) Security Alarm. It is commonly used for home, garage, or shed security to detect human movement via heat signatures. Technical Data Detection Range: Up to 5 meters (approx. 16 feet). Detection Angle: 110° wide-angle field of view. Siren Volume: 105dB (high-pitched deterrent).

Power Source: 4 x AA batteries for the main unit; button cells for remote controls. Operating Temperature: -10°C to +50°C. Application Use-Cases An Arduino or electronics learning kit sensor module

Driveway Alerts: Notifying you when a vehicle or person enters a specific zone.

Indoor Security: Temporary protection for rooms, closets, or sheds.

DIY Smart Alarms: Can be modified by hobbyists to trigger external relays or IoT notifications. 🔌 Pinout & Wiring (Adapter Version)

If you are using the YL-105 Transceiver Adapter, wire it to your microcontroller using this standard mapping:

VCC: Connect to 5V power (External or Microcontroller 5V pin). GND: Connect to common Ground.

CE/CSN/SCK/MOSI/MISO/IRQ: These pins pass directly through to the nRF24L01. Connect them to your SPI pins as required by your library (e.g., RF24 Library for Arduino). Which YL-105 are you working with?

I can provide specific code or installation steps if you tell me: Are you building a wireless communication link? Are you setting up a motion-activated security system?

I searched for a specific "YL-105" datasheet, but it is not a standard industry component code (like for a major IC, transistor, or sensor). This code is most likely used in one of two contexts:

An Arduino or electronics learning kit sensor module (common with "YL" prefixes, e.g., YL-69 for soil moisture, YL-83 for rain sensor).
A cheap, generic component from Chinese suppliers where the marking is a batch or internal factory code.

Here is how to find a helpful paper/datasheet for the YL-105, depending on what the component actually is.

Safety and Usage Tips

ESD Sensitivity: The 49E Hall sensor is sensitive to electrostatic discharge. Ground yourself before handling.
Magnet Placement: Keep magnets away from other sensitive electronics (HDDs, credit cards, pacemakers).
Temperature Effects: The 49E’s quiescent voltage drifts slightly with temperature. For precision work, recalibrate the potentiometer after thermal changes.
Power Supply: Use a regulated 5V supply. Ripple above 100mV can cause false triggering.

Application Examples Based on Datasheet Recommendations

Pinout Configuration

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

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

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