Yl-105 Datasheet

: Connect to 5V power (External or Microcontroller 5V pin). GND : Connect to common Ground.

Note: In some niche electronic contexts, "YL-105" may also refer to an 8-pin adapter board specifically designed for the radio module to simplify wiring and power regulation. Infrared Motion Sensor Alarm YL-105 Instruction Manual yl-105 datasheet

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). : Connect to 5V power (External or Microcontroller 5V pin)

Because it is a generic Chinese module, there isn't a single official manufacturer datasheet like you would find for a major IC (e.g., from Texas Instruments). However, the module is built around a specific RF chip, and its specifications are well-documented in hobbyist electronics. Infrared Motion Sensor Alarm YL-105 Instruction Manual In
