Uncovering a for the YL-105 module means looking past the bare-bones retail listings and synthesizing the specifications of the core components: the AMS1117 regulator and the nRF24L01 pinout architecture. Why a Standard YL-105 Datasheet Is Hard to Find
The YL-105 is a popular, low-cost capacitive soil moisture sensor. Unlike its resistive counterpart (the YL-69 or FC-28), the YL-105 uses a copper-plated probe to measure dielectric constant. In theory, this prevents corrosion. In practice, without a better datasheet , you face calibration hell. yl105 datasheet better
