TheRS-WS-*-TR is suitable for the measurement of soil temperature and moisture. By studying the dielectric properties of the main types of soils in China, and analyzing the physical and chemical characteristics of soils that may cause differences, three types of soils are used for comparative analysis. RepresentativeSoil moisture content(θ_v) andDielectric constant(K_a)Relationship modelAnd the suitability of various models. The test uses indoor packed soil columns. Different soils get a series of water content from drying to saturation and thenTDRDetermination. In order to improve the measurement accuracy, eight kinds of soil θ_v-K_a~(0.5) calibration formulas were established based on the actual water content and the measured dielectric constant. The accuracy of the water content measured after correction is 3-5 times higher than the accuracy of traditional measurement methods. This product has high precision, fast response and stable output. Less affected by soil salt content, suitable for all kinds of soil. It can be buried in the soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum potting, waterproof and corrosion resistant.

This product control chip adopts 16-bit high-precision imported processor to ensure sampling accuracy, 64M frequency, and ensure efficient operation speed. This product output signal 485 (Modbus protocol) and 4-20mA factory optional, please choose according to actual needs.

Centralized monitoring data customers can have the following options:

(1) The customer brings his own computer and uploads the concentrator data to our monitoring software

(2) Upload concentrator data to our free cloud platform

(3) Customer secondary development

TheOur 485 type transmitter is connected to our RS-RJ-K Renke temperature and humidity monitoring platform through the 485 bus. The centralized monitoring of temperature and humidity devices can be achieved through wired methods.

Monitoring platform software installation:

Monitoring platform interface operation:

RS-RJ-K software can set parameters locally and remotely via web pages. Local view, map mode, export historical data, SMS alarm settings, alarm data Word, Excel, ppt, pdf, local view, print historical curves and export pictures. Remotely view, export, and export history data and alarm data through web pages, view and print history curves and export images.

TheOur 485 type transmitter can be connected to our RS-ETH-M or RS-WIFI-M or RS-GPRS-M type concentrators and send data to the data via network port, WIFI or GPRS. Remote monitoring platform, a concentrator can access 8 485-type transmitter, a monitoring platform can access thousands of concentrators.

The environmental monitoring cloud platform is an environment monitoring platform developed and deployed on a cloud public network server based on the B/S architecture. The maintenance and management of the cloud platform is under the responsibility of our company. Users can apply for free access. Cloud platform can provide device data overrun, offline SMS alarm and email alarm service, free mobile phone APP, one-click login, easy to use.

Cloud platform address: www.0531yun.cn, neutral interface, easy to use the project. Customers can enjoy the "cloud platform use application form" when they purchase equipment.ofRight of use. At the same time, the company will issue customer names and passwords to customers. The customer can log in to the cloud platform to manage the equipment under the jurisdiction of the user name and password, and can assign sub accounts and sub account rights.
