Yl-105: Datasheet Verified

if (sensorState == LOW) // Object or white surface detected digitalWrite(ledPin, HIGH); Serial.println("Detected!"); else digitalWrite(ledPin, LOW); Serial.println("Clear");

This module is a breakout board designed to simplify the use of the 8-pin nRF24L01 wireless transceiver with microcontrollers like Arduino.

: 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.

RCSwitch mySwitch = RCSwitch();

Connecting remote, low-power sensors to a central hub.

Ensures the NRF24L01+ receives a stable and reliable 3.3V power supply, which is critical for reducing signal noise and ensuring reliable wireless communication.

The following is a sample YL-105 datasheet:

Detects when soil is too dry (needing water) or sufficiently wet, allowing for the automation of irrigation systems. 2. Technical Specifications (YL-105 Datasheet) yl-105 datasheet

The is a critical hardware accessory designed specifically for the popular nRF24L01+ 2.4GHz RF transceiver module . It solves the most common issues engineers and makers face when working with the transceiver: power supply instability and strict voltage constraints.

The YL-105 is often confused with or used in combination with popular sensors like the HR202 humidity sensor element. The module typically includes a humidity-sensitive resistive element and a comparator IC (such as LM393) to provide a clean digital signal alongside analog voltage changes.

Because “YL-105” is a module assembly rather than a single silicon component, there is from a major semiconductor house. However, you can obtain all necessary documentation by downloading:
