Abstract :Water resources, which are indispensable for agriculture, industry and domestic use, are under threat today. In order to use water and soil resources efficiently and sustainably, it has become an important need to develop new systems and methods that can detect the moisture content of the soil. With the developing technology and different techniques, the moisture content of the soil began to be measured more accurately, reliably and quickly. One of these techniques is measuring soil moisture with high-precision and low-cost capacitive sensors. In this study, an example system for measuring and recording soil moisture was designed using the Arduino microcontroller board and capacitive sensors. In the study conducted in a climate-controlled greenhouse, a very high negative correlation was found between sensor and gravimetric measurement values. The regression relationship between sensor values and gravimetric measurement values was examined and R2 values between 85.6% and 95.0% were obtained.
