Soil Moisture Temperature sensor for Drip Irrigation Smart Agriculture IoT

Soil moisture is the water content of the soil and is the most important and commonly used soil information. It is the basis for scientifically controlling and regulating the very condition of the soil, for water-saving irrigation, and for scientific water use and irrigation automation. The soil structure and the spatial variability of soil moisture cause the soil water content to vary in the same plot, which requires the measurement of soil water content.

The soil temperature and humidity sensor is suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland and pastures, soil rapid testing, plant cultivation, sewage treatment, precision agriculture and other occasions. The sensor adopts the FDR principle, and reflects the soil water content by measuring the dielectric constant of the soil. The measured soil value is the soil moisture volume percentage, which is the current standard soil moisture measurement method.

Monitoring the temperature and humidity of the soil helps people to understand the growing conditions of their crops and to determine whether irrigation is needed, which not only saves water but also promotes the growth of crops.

Soil temperature and humidity sensors monitor soil temperature and humidity and provide detailed data on soil moisture.

Soil temperature and humidity sensors are capable of measuring soil information at different depths and are highly accurate, easy to use and work well even when buried in the soil for long periods of time.

Traditional irrigation methods are more frequent and take longer to irrigate because the temperature and humidity cannot be grasped, which results in a huge waste of water.

By using the sensors to obtain information on soil moisture, water saving irrigation can be achieved, both in terms of timing and quantity, and also in terms of reducing water waste.

Soil moisture sensor is to measure the soil moisture content of the sensor, we also called soil moisture meter, soil moisture content (amount) sensor, etc., it is an online measurement of soil moisture moisture content changes in the agricultural Internet of Things sensor, often used to support the collection device to generate soil moisture speed meter, agricultural weather station, etc..

Soil moisture sensors on the market in general, there are two categories: needle-type soil moisture sensors: three-needle hygrometer, five-pin type, two-pin type, etc.

Tube type soil moisture sensor: mostly used for measuring soil temperature and humidity in layered profiles, with a spacing of 10cm multiples, measuring layers ranging from 1 layer to multiple layers, most manufacturers can customize on demand.

Measurement principle: FDR frequency domain method measurement, using the principle of electromagnetic pulse, according to the frequency of electromagnetic wave propagation in the medium to measure the dielectric constant of the soil (ε), so as to obtain the soil volume water content (θv).

Soil moisture installation summary: pin-type soil moisture sensor can be used in two ways: horizontal and vertical insertion .    

Horizontal insertion: Generally applicable to multiple sensors measured together with a spacing of 10cm to prevent mutual interference between sensors.

Use range role: soil moisture sensor is used to measure the moisture content of the soil, suitable for water-saving agricultural irrigation, greenhouse greenhouse vegetables, flower gardening, grass pasture, soil quick measurement, plant culture, scientific experiments and other fields.
