Quick soil moisture detector

The soil temperature and humidity rapid measuring instrument has powerful functions and can be used for moisture monitoring and water-saving irrigation in agriculture, forestry, environmental protection, water conservancy, meteorology and other industries. It can conduct field mobile field tests on various soil types, quickly and accurately detect the soil volumetric water content and temperature. It can not only test the surface moisture and temperature of the soil, but also the deep soil moisture and temperature, which can meet the needs of scientific research, production, teaching and other related work in the above-mentioned industries.



The fast soil moisture detector integrates soil moisture and soil temperature sensors to facilitate the measurement and research of soil moisture and soil temperature. It has the advantages of convenient carrying, sealing, and high precision. It is an ideal choice for soil moisture and soil temperature measurement.

The soil moisture part is based on the principle of time domain reflection, using high-frequency electronic technology to manufacture high-precision, high-sensitivity sensors for measuring soil moisture. By measuring the dielectric constant of the soil, it can directly and stably reflect the true moisture content of various soils.



The soil temperature part is composed of two parts, the A-level ST-1-PT1000 precision platinum resistance and the high-precision transmitter imported from Heraeus, Germany. The transmitter part is composed of a power supply module, a temperature sensor module, a transmission module, a temperature compensation module, and a data processing module. It completely solves the measurement error introduced by the platinum resistance due to its own characteristics. There is a zero drift circuit and temperature compensation in the transmitter. The circuit has high applicability to the use environment.
