Yl-105 Datasheet _hot_ -

The YL-105 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.

, a common resistive sensor often used for environmental detection in DIY electronics and smart gardening projects. Understanding the YL-105 Sensor Module: Datasheet & Guide yl-105 datasheet

The "YL" prefix indicates the manufacturer or PCB designer family (often associated with generic Chinese sensor modules), but the underlying sensor follows the standard 49E Hall effect sensor specifications. The YL-105 designation typically refers to two distinct

Output Type: Digital TTL signal (0 or 1). Usually, it outputs Low (0V) when an obstacle is detected and High (VCC) when the path is clear. yl-105 datasheet
