Soil moisture and drought monitoring instrument

　　Soil moisture and drought monitoring instrument——Built in data collector and wireless communication module (such as 4G/5G, LoRa) can automatically collect data at preset time intervals (such as every hour) and send it to the cloud data center in real time through the network.Soil moisture and drought monitoring instrument

1、 Product Introduction

A tubular soil monitoring station is an online monitoring device used to monitor soil profile temperature, soil profile humidity, and soil profile conductivity. It can be widely used in agricultural engineering fields such as smart greenhouses, smart orchards, and smart irrigation by collecting soil temperature, moisture, and conductivity.

2、 Product parameters

Solar panel power: 8W

Standard operating voltage for solar panels: DC5V

Built in lithium battery capacity: 5000mAh

Sensor startup time: 60 seconds

Sensor supply voltage: DC12V

Sensor power supply current: 22mA

Sensor power consumption: 0.26W

Communication method: 485 Modbus RTU protocol

Measurement parameters: capable of measuring 10 layers simultaneously

Measurement principle: Establish a mathematical model by measuring the soil dielectric constant, and design a spiral measuring electrode to measure soil volumetric moisture content data.

3、 Advantages and Characteristics

A single soil tube sensor can simultaneously measure soil parameters at multiple depths, and the monitoring depth can be customized (less than 1M).

The sensor adopts a low-power design, with a power consumption as low as 0.26W, suitable for long-term unmanned monitoring in the field.

Each layer of the sensor can independently measure temperature, humidity, and conductivity parameters.

The sensor housing is made of imported PC material, which has high strength, corrosion resistance, and no pollution to the environment.

The waterproof level of the sensor reaches IP67, which is suitable for long-term outdoor monitoring.

The sensor measures the average humidity within a certain area, which compensates for the limitations of single point measurement.

The sensor adopts a self-designed spiral measuring electrode to improve the contact between the sensor and the soil, and to avoid measurement errors caused by air gaps as much as possible.

4、 Precautions for use

a. The use of sensors should strictly follow the installation and use instructions.

b. When multiple sensors are working simultaneously, they must be spaced at least 3 meters apart.

c. The measurement principle of sensors is limited, and there should be no electromagnetic cables or strong magnetic radiation interference within a radius of 3 meters from the center of the sensor measurement site to avoid causing huge errors and damage to the sensor measurement.

d. The installation environment of the sensor should comply with the measurement range of the sensor and avoid non-standard behaviors such as exceeding the range.

e. The installation of sensors should avoid environments with strong acids, strong alkalis, heavy oil pollution, and heavy metals.

f. The sensor is a soil measurement sensor, and it is prohibited to use this sensor to measure other substances.

g. The sensor installation environment should not have strong vibrations.

h. Sensors should not be subjected to excessive external forces.

i. Disassembly is prohibited. Unauthorized disassembly is considered non compliant and no further service will be provided.
