soil temperature moisture sensor iot soil moisture sensors for smart farming

The soil temperature and humidity sensor is a high-precision, high-sensitivity soil moisture measuring instrument. The electromagnetic wave pulse emitted by the sensor is transmitted to the probe through the coaxial cable, and then enters the soil medium to measure the apparent dielectric constant of the soil, thereby obtaining the real water content of the soil. The influence of metal ions, etc. This instrument can be widely used in soil moisture monitoring, water-saving irrigation, greenhouses, grassland pastures, soil speed measurement and other fields.

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.

The wall-mounted temperature and humidity sensors are used to maintain the temperature and humidity inside the greenhouse so that the plants can produce well, but it is not enough to maintain the temperature inside the greenhouse, the plants also need the right soil temperature and humidity to grow.

To measure the temperature and humidity of soil, we usually use plug-in temperature and humidity sensors.

Soil temperature and humidity sensors can be connected to the corresponding sensors to collect data in real time, and can be used for computer management software to output data and generate reports.

Applications

With the emphasis on agriculture, soil temperature and humidity will be further adopted to serve agriculture, the sensor is widely used in scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grass pastures, soil speed measurement, plant culture, sewage treatment, food storage and a variety of particulate matter water content and temperature measurement, soil temperature and humidity will use its own excellent performance to serve agricultural production.

Soil sensors are playing an increasingly important role in monitoring crop irrigation conditions, soil air changes, and large area surface detection, data about soil moisture, soil nitrogen, phosphorus and potassium content and pH size, etc. Sensing technology is playing an increasingly important role in the development of precision agriculture, thus realizing scientific monitoring, rational planting, helping farmers to resist and mitigate disasters, improving the overall efficiency of agriculture, and promoting the transformation and upgrading of modern agriculture.
