When comparing the YL105 adapter to a direct connection, the advantages are clear: : Standard Arduino pins often provide only . The YL105 leverages the rail to provide up to
The YL-105 is functionally identical to the FC-37 / YL-83 in most cases. If you find a datasheet for those, the pinout and usage match.
For advanced wireless projects, consider the Arduino and NRF24L01 tutorial for step-by-step wiring instructions. Maximise supply chain efficiency | BradyID.com
| Missing Parameter | Why You Need It | | :--- | :--- | | | Air vs. Water capacitance (pF) to calculate dielectric constant. | | Temperature Coefficient | Output drifts ~2-5% per 10°C. Unknown in original sheet. | | AC Frequency | Most clones run at 1-10 MHz; frequency stability affects linearity. | | Rise Time | How fast does the sensor respond to wetting (99% FS)? (Actual: ~2 seconds). | | Adhesion Curve | Water clinging to copper vs. soil interface. |
is the standard for these modules and is highly recommended for stability. Troubleshooting
