Ph-dgtws-gprs soil moisture sensor is a soil moisture measuring instrument with high precision and high sensitivity. It can measure soil temperature and humidity at the same time. By measuring the dielectric constant of soil, it can directly and stably reflect the moisture content of various soils. The sensor has the advantages of low power consumption, small volume, convenient carrying, simple installation, operation and maintenance, etc
characteristic. Gprrs wireless is a built-in acquisition device, which can directly upload data to the Internet of things platform by matching the corresponding IP and port, and view data in real time with mobile phone; ◆ high quality plastic pipe is adopted, which can prevent aging and more resistant to the corrosion of acid, alkali and salt in the soil; ◆ using epoxy resin as sealing material can soak in water for a long time without seepage
Leakage; ◆ high measurement accuracy, reliable performance and less affected by soil salt content. It is used in various fields
Planting soil; ◆ impact resistant packaging is adopted for safer transportation and storage; ◆ it has multi-directional anti misconnection protection for power line, ground wire and signal line;
◆ it supports the monitoring of soil temperature and moisture in 4 layers by default, and can be customized if more layers are required; The sensor is used in water-saving agricultural irrigation, greenhouse vegetables, flower gardening, grassland and pasture, soil rapid measurement, plant culture, scientific experiment and other fields;
