Yl105 Datasheet
The yl105 datasheet may not exist as a single official document, but the electrical, mechanical, and timing specifications are well-defined by the components that make up this ubiquitous relay module. With its opto-isolated design, jumper-selectable logic, and 10A switching capability, the YL105 is an excellent choice for hobbyist and industrial applications alike.
Whether you are automating your home, building a robot, or designing a safety cutoff, the YL105 offers a reliable bridge between the fragile world of microcontrollers and the demanding realm of high-power electronics. Always respect the voltage ratings, adhere to proper wiring practices, and consult the SRD-05VDC-SL-C and PC817 datasheets for deeper technical insight.
Final Reminder: When working with AC mains voltage (110V/230V), take all necessary safety precautions. Use insulated enclosures, avoid live testing, and never leave the module powered while unattended.

The YL-105 is an adapter breakout board specifically designed for the nRF24L01+ 2.4GHz wireless transceiver module. Its primary function is to resolve common power supply and wiring issues encountered when interfacing these wireless modules with 5V microcontrollers like the Arduino Uno. 1. Key Technical Specifications
The YL-105 integrates a voltage regulator and filtering components to stabilize communication. Specification Input Voltage 5V DC (Accepts range 4.8V – 12V) Output Voltage 3.3V DC (to power the nRF24L01) On-board Regulator AMS1117-3.3 chip Max Output Current Up to 800 mA Compatibility 8-pin nRF24L01+ or nRF24L01+ PA+LNA modules Operating Temp -40°C to +125°C Dimensions 26 x 19 x 12 mm 2. Problems Solved by YL-105
Voltage Regulation: The nRF24L01 module requires a strict 1.9V to 3.6V supply. Standard Arduino 3.3V pins often lack sufficient current stability, leading to "brownouts" and dropped connections. The YL-105 allows you to use the more robust 5V rail.
Filtering: It includes on-board capacitors that act as filters to reduce noise on the power line, which is critical for stable RF transmission.
Ease of Wiring: It converts the module's 2x4 (8-pin) header into a breadboard-friendly single-row header with clearly labeled pins. 3. Pinout and Connections
The YL-105 adapter has 6 pins for interfacing with a microcontroller and an 8-pin socket for the wireless module.

Warning: Do not exceed these ratings. The relay may weld shut or catch fire.
The most significant challenge with the YL-105 is translating voltage into a standard unit of measurement: NTU (Nephelometric Turbidity Units).
Because the YL-105 is not a calibrated scientific instrument, it does not output "NTU" directly. To achieve this, you must create a lookup table or formula.
Connect YL105 output to an interrupt pin. Count pulses per minute using a magnet attached to a rotating shaft.
One of the main reasons engineers search for the yl105 datasheet is to understand the isolation voltage. The YL105 uses a PC817 optocoupler, providing electrical separation between the low-voltage control side (microcontroller) and the high-voltage load side.
However, note that many low-cost YL105 modules do not maintain true isolation if the jumper JD-VCC is shorted to VCC. For proper isolation:
For data logging and smart monitoring, the A0 (Analog) pin is the primary interface of interest.
In an automated aquarium, the YL-105 monitors water clarity. If the voltage drops below a set threshold for 10 minutes (filtering out momentary disturbances), the system triggers a water pump to perform a partial water change.
Since an official unified datasheet for "YL105" is rare (the number often refers to a module, not a single IC), below are the typical electrical and magnetic specifications derived from common Hall sensors used in YL105 modules.
