Abstract:

Based on the traditional FDR automatic soil moisture sensor, we developed a new type of automatic soil moisture sensor by redesigning the measuring circuit. In the laboratory, the electrical performance, measurement performance, resistance to temperature changes and resistance to saline and alkali of the new automatic soil moisture sensor were compared with those of the traditional FDR automatic soil moisture sensor. The comparison results showed that: the new automatic soil moisture sensor could realize continuous monitoring of soil moisture and meet the measurement performance requirements; the calibration process of the new automatic soil moisture sensor was relatively simple, the measurement accuracy was higher, the anti-interference ability was stronger, and the stability was better. The new automatic soil moisture sensor could improve the accuracy and stability of soil moisture monitoring, and provide technical support for upgrading the automatic soil moisture observation instrument.

Key words: soil moisture, sensor, automatic observation, sensor performance
