Our company independently develops and produces a mobile soil moisture monitoring device, also known as a soil moisture analyzer. The mobile soil moisture monitoring device has GPS positioning function. Can display the information of sampling points (longitude, latitude) at any time, and display the location information of sampling points at any time.

Mobile soil moisture monitoring device/Soil moisture analyzer​Principle:
The mobile soil moisture monitoring device emits a signal of a certain frequency, which is transmitted by the signal source probe and reaches the soil end. Due to impedance mismatch, some signals are reflected back to the transmission line, forming a standing wave superposition with the original signal. Since the reflectivity depends on the dielectric constant of the soil, which is linearly related to the soil moisture content, the standing wave superposition signal can be detected to obtain the soil moisture content.

Mobile soil moisture monitoring device/Soil moisture analyzerFunctional features:
Host functional features:
1. Equipped with wireless transmission function, uploaded through GPRS, the measured data can be sent to the server in real-time with one click or set the data transmission interval. The data can be viewed and downloaded from anywhere as long as there is internet access;
2. Equipped with a mobile app that supports both Android and Apple systems, real-time data can be viewed from anywhere as long as there is internet access;
3. Low power design, increased system monitoring and protection measures to avoid system crashes;
4. Chinese LCD display, capable of displaying current date and time, sensor measurement data, storage capacity, number of stored data, and other information;
5. The host has a large data storage capacity: the internal Flash of the device can store the latest 30000 pieces of data, and the standard 4G memory card can store unlimited amounts of data, and can also store data simultaneously with Flash;
6. Built in lithium battery power supply: 7.4V2.8Ah lithium battery, with charging protection and low voltage prompt function. The external power supply is an 8.4V (1000mA or above) DC power supply;
7. Collection settings: Used without human supervision, it can be set to collect data at regular intervals or manually;
8. Voice settings: The voice broadcast function can be set to be on/off/over limit as needed;
9. Voice alarm function: When the host voice is set to over limit, it can broadcast over limit information through voice;
10. The host can connect different types of sensors through a hub without affecting each other's accuracy;
11. Equipped with GPS positioning function, the geographic coordinates of the collection point can be automatically displayed during data collection;
12. Expandable sensor types and quantities, up to 32 types (with IP67 extension cable and integrated structure).
Manage cloud platform functions:
1. The built-in instrument cloud management platform includes a C/S architecture, which can summarize and analyze data from all portable and online devices without losing data backup. The viewing and operation methods include both web and mobile devices (available on Android/Apple systems);
2. Display the data collected by each sensor, detection time, and GPS coordinate information of the collection location;
3. Data can be uploaded to the management cloud platform through GPRS or USB data cable import. Data within the platform can be downloaded, analyzed, and printed;
4. The platform supports device data storage and provides sufficient capacity for unlimited storage;
5. The platform provides report formats such as curves and tables for device data, and the data can be exported and imported;
6. The platform can combine data to create reports, print reports, and export reports;
7. The software can be upgraded online.

Introduction to the Collector and Accessories:
Collector:A data acquisition device is a system that collects environmental data. A data acquisition device can be connected through a multi-channel hub and can be externally connected to multiple sensors of the same or different types. Each sensor can also be connected separately and work independently

Hub:If multiple sensors need to be connected at the same time, they need to be connected through a hub. Hubs have one to four and one to six configurations, which can be configured as needed during actual use (wireless sensors are not required)

data line:The data cable is used to connect the data acquisition device and the computer, and can upload the data from the acquisition device to the upper computer software for data reading, management, and querying

The power adapter:Use a power adapter to charge the data acquisition device. Check if the charging is complete according to the charger's instructions

Other soil instruments:Soil nutrient rapid tester, soil acidity meter, soil moisture analyzer, soil moisture, temperature, salt three parameter rapid tester, soil water potential analyzer, soil bulk density analyzer, soil hardness tester, soil compaction analyzer
