FDR Soil Sensor Soil Temperature Moisture Tester For Precision Agriculture

Soil temperature and humidity sensor is equal to the combination of soil temperature sensor and soil humidity sensor. The monitoring of soil temperature and humidity enables us to understand the soil condition in time, analyze the soil drought and flood conditions and the impact on the growth and development of crops, which helps transform traditional agriculture into modern agriculture and promotes the development of "smart agriculture".

In addition, based on the measured soil temperature and humidity data, we can predict floods, droughts and other natural disasters in a timely manner to help protect and build the ecological environment.

Based on the principle of dielectric constant, the sensor can monitor soil temperature and humidity at different levels in real time, realize dynamic observation of moisture content in each soil layer, visualize soil salt accumulation, and quickly and accurately monitor soil temperature and humidity in different soil layers. Soil parameter quick test instrument is widely used in the field of soil testing in smart agriculture, orchard nursery, demonstration park, smart city, etc.

Soil moisture sensors, also known as soil moisture meters, are mainly used for measuring soil volumetric water content, monitoring soil moisture, agricultural irrigation, forestry protection, etc.

At present, the commonly used soil moisture sensors are FDR type and TDR type, i.e. frequency domain type and time domain type.

NiuBoL soil moisture sensor is using FDR frequency domain method measurement, the sensor built-in signal sampling and amplification, drift zero and temperature compensation function, user interface is simple and convenient.

Measuring range: 0~100%, measuring accuracy: ±3%. The product is compact, corrosion resistant, accurate and convenient to measure.        

The soil moisture sensor is a device that measures the current soil moisture. The sensors are integrated into agricultural irrigation systems to help efficiently schedule water supply. This meter helps to reduce or enhance irrigation for optimal plant growth. 

Capacitive soil moisture sensors: Using the dielectric properties of soil to measure soil moisture content is also an effective, fast, simple and reliable method.

For the capacitive soil moisture sensor with a certain geometric structure, its capacitance is proportional to the dielectric constant between the two poles of the measured material.

Since the dielectric constant of water is much larger than that of ordinary materials, when the moisture in the soil increases, its dielectric constant increases accordingly, and the capacitance value given by the moisture sensor increases during measurement.

The correspondence between the capacitance of the sensor and the soil moisture can measure soil moisture. Capacitive soil moisture sensors have high accuracy, wide range, a wide variety of measurable materials, and fast response time, and can be applied to online monitoring.
