PulseWetProbe 0.3.7 — Production-ready Arduino Library Release

PulseWetProbe 0.3.7 — Production-ready Arduino Library Release

PulseWetProbe is an Arduino library for MCU-only pulsed electrode sensing. It is designed for wetness detection, soil-moisture trend monitoring, conductivity-trend estimation, surface-state experiments, diagnostics, calibration workflows, and low-power field sensing with common Arduino-compatible boards.

This release prepares PulseWetProbe for public use and Arduino Library Manager submission.

Highlights

• Arduino Library Manager-ready package structure.
• MCU-only two-electrode sensing without a dedicated external analog front-end.
• Pulsed electrode drive to reduce continuous electrode stress.
• Reversible two-plate role balancing for more stable long-term experiments.
• High-impedance rest behavior to help reduce corrosion and polarization effects.
• Dry/wet calibration and multi-point calibration workflows.
• Board-aware defaults for common AVR, ESP32, RP2040, SAMD, STM32, megaAVR, Renesas, and Teensy-style Arduino environments.
• Fixed-memory filtering suitable for embedded targets.
• Hampel-style outlier filtering, EMA smoothing, moving-average filtering, and adaptive filtering behavior.
• Wetness classification, moisture trend tracking, conductivity trend output, and surface-state style sensing.
• CSV and JSON output helpers for logging, serial monitoring, dashboards, and data pipelines.
• Diagnostics for raw ADC, filtered values, baseline behavior, noise, confidence, and state changes.
• Power-aware sampling support for battery-oriented sensing workflows.
• Example sketches for quick start, calibration, diagnostics, low-power use, JSON output, and advanced sensing workflows.

Bug fixes and hardening in v0.3.7

• Fixed moving-average circular-buffer behavior so the filter uses recent samples consistently.
• Fixed conductivity-trend weight-selection priority so conductivity and brine-style profiles are not unintentionally overridden by reversible-mode defaults.
• Added host smoke-test coverage for the moving-average and conductivity-trend fixes.
• Improved release metadata consistency for Arduino and GitHub publication.
• Updated README presentation with clearer installation, calibration, examples, diagnostics, and safety notes.

Intended use cases

• Arduino wetness sensor projects.
• Soil moisture trend monitoring.
• Two-electrode moisture sensing experiments.
• Conductivity trend and surface condition experiments.
• Low-power outdoor or field sensing prototypes.
• Industrial IoT and telemetry prototypes.
• Serial logging, CSV logging, JSON telemetry, and dashboard integration.
• Educational sensing, calibration, and embedded diagnostics projects.

Important accuracy note

PulseWetProbe reports relative wetness, moisture trend, conductivity trend, and sensor-state information from a simple two-electrode setup. It does not claim certified electrical conductivity, salinity, freezing-point, road-weather, RWIS, or laboratory-grade measurement accuracy.

For safety-critical, regulatory, environmental, agricultural, road-weather, or industrial-control use, validate the complete hardware, electrodes, calibration method, enclosure, installation, firmware, and data interpretation against suitable reference instruments and field conditions.

Arduino compatibility

This library is written for Arduino-style C++ projects and is intended to work across a broad set of Arduino-compatible architectures through board-aware defaults and portable code paths.

Typical target families include:

• AVR boards such as Arduino Uno and Nano.
• ESP32 boards.
• RP2040 boards.
• SAMD boards.
• STM32 Arduino cores.
• megaAVR boards.
• Renesas-based Arduino boards.
• Teensy-style Arduino environments.

Installation

After Arduino Library Manager indexing, the library should be installable from:

Arduino IDE → Library Manager → search for PulseWetProbe

Until then, it can be installed manually from this GitHub release ZIP or from the repository source.
