Product Details

Product Description:

The soil moisture monitoring system is a soil moisture wireless sensor acquisition system with wireless data collection and transmission functions. Composed of a low-power, high-precision wireless data acquisition terminal and a soil temperature and humidity sensor. The data collection terminal has the ability of automatic collection and long-term low-power operation, and supports SDI-12, the internationally recognized sensor data collection protocol; Support 1-5 soil temperature and humidity probes. The temperature and humidity sensor is based on the frequency domain dielectric constant detection principle and is compatible with internationally recognized soil detection sensor specifications.

1、 Functional characteristics of soil temperature sensor

1. The temperature is calibrated using a professional constant temperature bath (usually manufacturers do not have professional calibration equipment, even if the sensor accuracy is high, the accuracy and stability will still decrease after integrated transmission)

2. Humidity adopts imported high-precision industrial chips

3. Integrated design with strong scalability, capable of simultaneously selecting measurement elements such as temperature, humidity, and air pressure

4. Scalable wireless function, easy installation, saving labor and material costs for wiring

5. The anti radiation cover design protects the sensor from harsh environments such as strong winds, rain, and snow, as well as interference from radiation and other factors, allowing the sensor to truly sense changes in the external environment

2、 Functional characteristics of soil moisture sensor

1. The soil moisture sensor is calibrated using the drying method specified in the Agricultural Meteorological Observation Specification

2. The soil moisture sensor adopts a 4-probe ring structure design, which can measure the area inside the ring. It has a large measurement area and high stability (different from the 3-probe flat structure, which can only measure strip areas, with fewer probe measuring points and poor stability)

3. The soil moisture sensor uses ABS engineering plastic with high compressive strength, which can be directly applied to harsh environments such as saline alkali soil (different from environmentally friendly PVC plastic with low cost and poor impact resistance)

4. Adopting long-distance 485 communication without external transmission equipment, it is convenient to embed pipes and greatly enhances anti-interference ability (solving the problem of sensor 485 communication requiring external transmission and inconvenient pipe routing)

5. Optional soil moisture and soil temperature sensors are available for easy pre embedding and wiring, saving wiring materials and labor costs, while also facilitating the implementation of layered pre embedding requirements in meteorological observation standards

3、 Meteorological data acquisition instrument

Adopting a new generation ARM core 32-bit processor with fast computing capability, equipped with a 12 bit A/D sampling conversion module and high-precision components, combined with temperature compensation and precision correction technology, data acquisition becomes more accurate.

1. Strong scalability, capable of expanding 16 analog/counting channels, 16 digital I/O channels, 4 serial ports, 1 CAN bus interface, and 1 USB storage interface

2. Adopting industrial standard design and scientific research acquisition instrument, suitable for various end environmental conditions

3. Strong compatibility, can integrate various sensors

4. Support LED monochrome screen and color touch screen expansion

5. Support remote switch control function expansion

6. Support remote application updates, program changes, and upgrades without the need to return to the factory

7. Support time calibration function

8. Supports WIFI, Ethernet ZIGBEE、 optical fiber GPRS、 Multiple communication methods such as satellites

9. Support XPH and standard MODBUS dual protocol switching; Facilitating secondary development for users
