Understanding the pinout is essential. The YL-105 module typically exposes four pins (or a 4-pin header):
. This module is a versatile, low-cost sensor often paired with an LM393 comparator chip to provide both digital and analog outputs. While frequently used as a soil moisture sensor (similar to its sibling, the ), the YL-105 is also found in configurations for rain detection liquid level sensing Technical Specifications yl-105 datasheet
