Datasheet - Yl-105

A compact footprint of 26 x 18.6 x 10mm and a weight of roughly 3g .

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

Features an onboard potentiometer to calibrate the sensitivity of the digital trigger. Indicator LEDs: A compact footprint of 26 x 18

Note: Some budget clones swap the pin order. Always check the back of your PCB for labels. The sensor usually requires a 4-wire or 6-wire

The sensor usually requires a 4-wire or 6-wire configuration for excitation (V+, V-) and signal output (S+, S-).

. 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
