Soil/Moisture Sensor

The soil temperature, humidity and salt integrated sensor (soil integrated sensor) is a high-precision, high-sensitivity multi-parameter sensor. Based on dielectric theory and independently developed using frequency domain measurement technology, it can accurately measure soil temperature and humidity and the volumetric water content of other porous media. The sensor integrates soil temperature and humidity sensors, soil conductivity, and soil salinity, and is also an important tool for monitoring the occurrence, evolution, improvement, and long-term dynamic monitoring of saline soil.

Note: For analog output, only two of the elements can be selected for output.

Soil moisture sensor is a high-precision and high-sensitivity soil moisture sensor. By measuring the soil dielectric constant, it can directly and stably reflect the true moisture content of various soils. The soil moisture sensor adopts a soil moisture measurement method that meets international standards and can measure the volume percentage of soil moisture. It is suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouses, greenhouse control, precision agriculture, etc., and also for water conservancy, meteorology and the measurement of moisture content of various particles.

Soil moisture, temperature and conductivity sensor, which can measure soil volume moisture content, temperature, conductivity, dielectric constant, signal propagation time and signal attenuation. It can accurately measure moisture content without calibration for specific soil. Moisture content is calculated from dielectric constant. Soil conductivity is calculated from signal attenuation value. Soil temperature is measured by thermistor. Signal attenuation is used to correct reflected wave and signal propagation time. It can be installed anywhere.

Soil pH sensor, using internationally advanced solid dielectric and large-area polytetrafluoroethylene liquid junction, the sensor is not easy to clog, almost maintenance-free, more suitable for field soil pH online real-time monitoring. The sensor electrode uses high-quality low-noise cable, which can make the signal output length more than 20 meters without interference.

Soil temperature sensor, made of high-quality sensor core and 304 stainless steel shell. Fully sealed design, with strong structure, long service life, high measurement accuracy, good stability, micro power consumption, long transmission distance, strong anti-interference ability, etc., in line with the WMO World Meteorological Organization specifications (CIMO Guide). It can be widely used in meteorology, environment, agriculture, aquaculture, greenhouses, laboratories and other occasions where soil temperature measurement is required.

Soil heat flux sensor (also called soil heat flux plate) is a device that measures soil energy balance and thermal conductivity of soil layer in real time. The sensor uses a thermopile to measure temperature gradient, which is composed of two different metal materials. The thermopile detector receives thermal radiation, which can generate a temperature difference potential between two different material nodes and output a weak millivolt voltage signal proportional to the heat flux. It can also be used to measure the heat flux of building exterior walls and exterior coatings.

The soil nitrogen, phosphorus and potassium three-in-one sensor (also called soil nutrient rapid tester) is suitable for detecting the content of nitrogen, phosphorus and potassium in the soil. By detecting the content of nitrogen, phosphorus and potassium in the soil, the fertility of the soil can be judged, which is convenient for systematic evaluation of the soil conditions. It can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, and completely waterproof. Note: The pseudo-quantity output signal can only output two of the elements.

Soil moisture rapid tester/soil moisture tester, using embedded technology, modular structure, with built-in LCD display, this soil moisture rapid tester can be connected to soil temperature and humidity, salinity, nitrogen, phosphorus, potassium, pH value and other sensors. Modular structure, can flexibly add or reduce corresponding modules and sensors according to user needs (measured elements), any combination, convenient and fast to meet the needs of various users, this soil moisture rapid tester internal power supply system can power various sensors, wiring is simple and convenient.
