In the burgeoning field of environmental monitoring and smart agriculture, the ability to digitally quantify the clarity of a liquid is a fundamental requirement. While industrial water quality stations utilize nephelometers costing thousands of dollars, the hobbyist and prototyping markets rely on accessible, low-cost alternatives. Chief among these is the .

The YL105 designation itself is not a standalone part number but a used by Alpha Wire. In the company’s nomenclature, "YL" stands for Yellow , and "105" typically indicates a specific packaging configuration (commonly a 4‑foot length supplied as part of a multi‑piece package).
Controlling multi-speed settings or sleep timers.
A rating of provides excellent electrical insulation, helping to prevent short circuits and electrical breakdown in densely packed cable bundles. yl105 datasheet
An evaluation of the specifications confirms how this breakout board resolves these hardware incompatibilities. By embedding a dedicated on-board low-dropout (LDO) voltage regulator and breaking out the complex 8-pin RF footprint into a standard, breadboard-friendly layout, the YL-105 simplifies low-power wireless networking. Technical Specifications & Operating Limits
is a specialized power regulator and hardware interface module designed specifically for the popular Nordic Semiconductor nRF24L01+ 2.4GHz RF transceiver module . It addresses one of the most widespread challenges encountered by embedded systems engineers and electronics hobbyists: supplying stable, noise-free current to an ultra-low-power radio component from a standard 5V system microcontroller, such as an Arduino Uno.
: Power input pin connected to the 5V line of the microcontroller. GND : Common ground pin connected to the system ground.
Placed closest to the 8-pin female terminal to clear away high-frequency RF ripple noise, stabilizing the transceiver's onboard Phase-Locked Loop (PLL) synthesizer. 🔌 Hardware Hookup Guide to Microcontrollers In the burgeoning field of environmental monitoring and
: Transmits configuration data from the MCU to the radio.
Disclaimer: Specifications are based on common manufacturer standards for the "YL-105" or "NRF24L01 Adapter" components.
The sensor consists of a waterproof probe containing two key components:
: SPI data input. Connects to the hardware SPI MOSI pin (Pin 11 on Arduino Uno). Arduino and NRF24L01 : 6 Steps (with Pictures)
For projects requiring more robust mechanical protection and sealing, the FIT®-300 series is an excellent choice. This tubing is classified as "semi-rigid" and provides superior wall thickness and abrasion resistance. It differs from the FIT®-221 series in two major ways: a higher and a higher recommended shrink temperature of 140°C .
The YL-105 break-out board features two main connector sections: a 6-pin male header row for your microcontroller connections and an 8-pin (2x4) female socket designed to seat the radio transceiver module. Microcontroller Interface (Input Headers) : Common Ground return connection.
