Yl-105 Datasheet Work Page

The designation typically refers to two distinct types of devices in the electronics world: a PIR Motion Sensor Alarm unit and a Transceiver Adapter Module used for wireless communication.

The YL-105 adapter is a popular breakout board designed to solve power stability issues with . Because these radio modules are sensitive to voltage fluctuations, the YL-105 provides a regulated 3.3V supply from a 5V source. Key Specifications Input Voltage 4.8V – 12V DC Output Voltage 3.3V DC (Regulated) Onboard Regulator AMS1117-3.3 Max Current ~800mA (Peak) Pinout Compatibility 8-pin (2x4) nRF24L01 modules Features & Benefits

🛠️ : Bridges the gap between 5V microcontrollers (like Arduino Uno) and 3.3V wireless chips. yl-105 datasheet

: Temporary protection for rooms, closets, or sheds.

: These pins pass directly through to the nRF24L01. Connect them to your SPI pins as required by your library (e.g., RF24 Library for Arduino). Which YL-105 are you working with? The designation typically refers to two distinct types

In consumer electronics, the YL-105 is a standalone . It is commonly used for home, garage, or shed security to detect human movement via heat signatures. Technical Data Detection Range : Up to 5 meters (approx. 16 feet). Detection Angle : 110° wide-angle field of view. Siren Volume : 105dB (high-pitched deterrent).

: Can be modified by hobbyists to trigger external relays or IoT notifications. 🔌 Pinout & Wiring (Adapter Version) Key Specifications Input Voltage 4
