4、 Product features:
The soil temperature and humidity recorder adopts an integrated structure, which integrates the data collector, sensor and into a chassis, which is very convenient to install
The outer case is pressed with plastic resin material mold, which is beautiful and firm, and the installation is extremely simple
It can be tested by hanging at any place

The portable waterproof and shockproof structure has the ability of wind, rain, shock, corrosion and strong magnetic interference
It does not need manual intervention during operation
It is suitable for use in the field and harsh climate environment

The recorder can be equipped with large screen LCD, with Chinese character and graphic display function
One screen displays multi-channel data, and can view real-time monitoring data and various setting parameters

The host of the instrument adopts high-performance microprocessor as the main control CPU and large capacity data memory, which can continuously store 100000 pieces of data
And the storage time can be set

The instrument is equipped with professional soil analysis software, which can store, download and store the stored data in Excel standard format into the microcomputer, and can also generate various soil analysis charts

In order to facilitate the setting of sensors for measuring depth and soil sampling, soil drills can be equipped

The machine has small volume, simple software operation and reliable performance
The recording interval can be set arbitrarily from 1 minute to 24 hours as required

The whole process * records the temperature and humidity data in the measured environment for a long time, and has the function of automatic storage and protection of power-off data


the power consumption of the whole machine is small, and the built-in battery is used for power supply

The software has powerful functions and convenient data viewing
The data in the recorder can be exported to the computer at any time, and can be stored as excel table file to generate data curve for further data processing by other analysis software

A single recorder can be connected with up to 16 temperature probes, which can measure the temperature and humidity distribution in air, water or soil

The recorder can work independently without the computer
When it is necessary to view the current environmental data, the data in the recorder can be read by the computer through the communication interface

A recorder can measure the temperature, soil temperature and humidity at multiple points at the same time

5、 Product overview
Suitable soil temperature and humidity is an important environmental condition for crop growth
It not only directly affects the growth and development of crop roots and the activities of soil microorganisms, but also affects the movement of water in soil
Therefore, in order to protect soil temperature and humidity and promote the growth of crops, people need to collect and deal with soil temperature and humidity to keep it within a certain range

The soil temperature and humidity recorder is a new type of environmental testing instrument launched by our company according to the market demand
The instrument can collect data in real time when connected with corresponding sensors, and can output data and generate reports with computer management software
The instrument can also collect the specific longitude and latitude position of each specified point through GPS receiver
The recorder can automatically store the soil moisture value, temperature value, longitude and latitude position value of each specified point, and can also be transmitted to the computer through RS-485 serial port for storage and processing

6、 Product composition
Soil temperature and humidity sensor, data collector, soil temperature and humidity tester, communication system, power supply device, etc

The system adopts master-slave structure, which is composed of sensor unit, power module, communication module, data acquisition center computer and so on; The small system composed of acquisition part belongs to the slave equipment, and the computer (server) of data acquisition center belongs to the master equipment
The networking mode between the computer of the data acquisition center and the on-site observation station adopts the GPRS data communication network to transmit the element data of the monitoring observation station
The central computer can carry out data transmission, remote update, remote configuration, remote debugging and other related operations with multiple slave devices

The multi-channel data acquisition instrument can be equipped with up to 16 soil temperature or soil humidity sensors, which can continuously measure the soil temperature and humidity of different soil layers; The equipped soil moisture sensor meets the TDR (time domain reflection method) technical standard of the water conservancy industry standard of the people's Republic of China sl364-2006 code for soil moisture monitoring, which is convenient for soil on-site calibration and measurement; The soil temperature sensor adopts high-precision imported sensor chip, with high measurement progress and good stability; The powerful soil moisture computer center software can synchronously process the data of multiple soil moisture sites and easily realize the networking management between soil moisture sites
