Yl-105 Datasheet

Since no official YL-105 datasheet exists, here are the actual technical specs you need for circuit design and coding.

Based on standard hardware data, the YL-105 module typically follows these parameters: Operating Voltage: Output Type: Dual output (Analog and Digital). Analog (A0):

The YL-105 is very popular in the Arduino community due to its simple interfacing. Wiring Diagram YL-105 Pin Arduino Pin GND DO Pin 2 (Digital) AO A0 (Analog) Example Code (Analog) yl-105 datasheet

: Communities such as Arduino Forum, Electronics Stack Exchange, and Reddit's r/AskElectronics contain discussions from users who have worked with specific YL-105 devices and can provide practical guidance.

YL-105 Datasheet: Complete Specification & Technical Guide The is a high-utility hardware accessory designed to resolve the power instability issues common to the nRF24L01 2.4GHz wireless transceiver module. While the Nordic Semiconductor nRF24L01 features 5V tolerant data inputs, its core power supply ( VCC ) must strictly remain between 1.9V and 3.6V DC . Since no official YL-105 datasheet exists, here are

The primary challenge with the nRF24L01 module is its strict , while most standard Arduinos operate at 5V . Connecting a wireless module directly to a 5V pin can permanently damage it. The YL-105 Adapter bridges this gap by converting a 5V input into a stable 3.3V output for the radio. Key Specifications Onboard Regulator: Integrated AMS1117 3.3V chip.

void setup() Serial.begin(9600); void loop() int moistureLevel = analogRead(A0); Serial.print("Soil Moisture Level: "); Serial.println(moistureLevel); if (moistureLevel > 800) Serial.println("Soil is Dry - Time to Water!"); else Serial.println("Soil is Wet - Good."); delay(1000); Use code with caution. 6. Tips for Longevity Wiring Diagram YL-105 Pin Arduino Pin GND DO

: Emits a piercing 105dB alarm to deter intruders.

: Optional pin to mask or trigger hardware interrupts for data-ready or transmission-sent flags. ⚡ Circuit Diagram and Schematic Overview

The YL-105 is a compact electromagnetic relay that is used to control the flow of electrical current in industrial control systems, power supplies, and other applications.
