What is the function of mobile soil moisture monitor?

1. The mobile soil moisture monitor emits a signal with a certain frequency, which is emitted by the signal source probe and reaches the soil end. Due to impedance mismatch, part of the signal is reflected back to the transmission line, thus forming a standing wave superposition with the original signal. Because the reflectivity depends on the dielectric constant of the soil, and the dielectric constant of the soil has a certain linear relationship with the soil water content, the soil water content can be obtained by detecting the superposition signal of the standing wave.

Second, the characteristics of mobile soil moisture monitor/mobile soil moisture tester/soil moisture monitor:

1, compact and beautiful, easy to carry, light touch button, large screen dot matrix LCD display, full Chinese menu operation.

2. Collection setting: it can be used unattended, and can be set as regular collection or manual collection. Automatically record data and store it.

3, AC and DC dual-use, built-in lithium battery power supply: 3.7v4Ah lithium battery, with charging protection and low voltage prompt function. It can also be placed for a long time.

4. It has GPS positioning function, which can display the latitude and longitude of the acquisition point in real time and save it. (optional)

5. With voice broadcast function, voice alarm can be set for overrun values, real-time Mandarin voice broadcast can be performed for overrun parameters, and real-time environmental parameter values can also be directly broadcast.

6. The data storage function is powerful. The internal flash memory of the device can store the latest 30,000 pieces of data, and the standard 4G memory card can store it indefinitely or simultaneously with the data in the flash memory.

7. You can view the data on the host computer or import it into the computer.

8. After unexpected power failure, the data saved in the host will not be lost.

9. The probes are consistent, and the host can access different types of sensors through the hub, which does not affect the accuracy of each other.

10. After the sensor is plugged into the host, you can manually collect different kinds of sensors for several minutes (similar to the automatic sensing when the USB flash drive is connected to the computer).

1 1. This instrument has the extended function of 32 simultaneous detection, which can realize multi-point synchronous detection and can be combined by itself as required.

12. Wired RS485 communication. The farthest communication cable of sensor can reach 100 meter.

13. Low power consumption design, adding system monitoring and protection measures to prevent the power supply from being damaged due to short circuit or external interference and avoid system collapse.

Four, mobile soil moisture monitor/mobile soil moisture tester/soil moisture tester PC software functions:

1. Displays the process curve trend of each parameter, and displays the functions of viewing, zooming in and zooming out.

2. It has the function of setting the coloring of the overrun area, which makes the display more intuitive and brings more convenience to customers.

3. The recorded data can be backed up and saved in EXCEL format for future use.

4. Reports and graphs of various parameters can be queried and viewed by time period, and can be printed by computer.

5. The curve coordinates can be set and moved by themselves, which can analyze the historical trend more clearly and grasp the time more clearly.

Verb (abbreviation of verb) mobile soil moisture monitor/mobile soil moisture tester/collector and accessories introduction: collector: collector is a system for collecting environmental data. A collector can be connected through a multi-channel hub, and multiple sensors of the same or different kinds can be connected externally, and each sensor can also be connected and operated independently. Hub: If you need to connect multiple sensors at the same time, you need to connect through the hub. The hub has one for four purposes and one for six purposes, and it is configured as required in actual use (no wireless sensor is used). Data line: the data line is used to connect the acquisition instrument and the computer, and the data in the acquisition instrument can be uploaded to the upper computer software for data reading, management and inquiry. Power adapter 8.4V/ 1.5A: Use the power adapter to charge the collector, and whether the charging is completed shall be subject to the instructions of the charger.
