Data files for "Field Performance and Calibration Strategies for Low-Cost Capacitive Soil Moisture Sensors" published in Sensors

This dataset contains the full package of code, documentation, and laboratory and field data for a low-cost Arduino-based soil moisture monitoring system. The system uses capacitive soil moisture probes, an Arduino UNO, a Real-Time Clock (RTC), and a microSD card module to log soil moisture in the field.

For more information, please see Strypsteen, G., M. Persson, M. Miroshnychenko, and N. Rakonjac. (2026) Field Performance and Calibration Strategies for Low-Cost Capacitive Soil Moisture Sensors, published in Sensors. See this paper for a full desciption of the setup.
