Yl105 Datasheet Better -

The YL-105 is commonly known as a . It detects water or moisture levels and outputs both:

Integrated 1.2-A synchronous boost converter with I2C interface for brightness control. Potential Match 3: LDO Voltage Regulator (NCP105) If used for power regulation, it may refer to the , a 150 mA Low Dropout (LDO) regulator. Input Voltage: 1.7V to 5.5V.

10 ~ 30VDC (12V recommended), allowing compatibility with most PLC and SCADA systems. yl105 datasheet better

: Supports the standard 8-pin nRF24L01+ and nRF24L01 PA LNA modules. Dimensions : 26 x 19 x 12 mm. Pinout and Connection Guide

Place high-frequency ceramic decoupling capacitors as close as possible to the VCC and GND pins. Keep trace lengths under 2mm to minimize stray inductance. Power Loops The YL-105 is commonly known as a

The nRF24L01 and nRF24L01+PA+LNA modules require a . Many Arduino boards (like the Uno or Nano) have a 3.3 V output, but that output often cannot supply enough current for reliable operation, especially when the radio transmits at high power. Moreover, the nRF24L01’s 2×4 pin header is physically awkward to breadboard. The YL‑105 adapter fixes both issues.

voltage regulator chip to convert 5V–12V input down to a stable 3.3V for the radio. Power Stability : Includes integrated bypass capacitors Input Voltage: 1

// Datasheet threshold: 30 µs is the boundary if(duration > 30) = (1 << (7 - i));

Connect the remaining SPI pins to the corresponding hardware SPI pins of your specific controller (e.g., Pins 11, 12, and 13 on an Arduino Uno).

The datasheet is better than online tutorials because it confirms you must disable interrupts during the 40-bit read. If you use delayMicroseconds() without disabling interrupts, you will get CRC errors. Use noInterrupts() and interrupts() in Arduino, or portDISABLE_INTERRUPTS() in ESP-IDF.
