MC-GSW Ultrasonic Tube Type Automatic Soil Moisture Monitoring System

MC-GSW Ultrasonic Tube Type Automatic Soil Moisture Monitoring System

1、 Product principle and application:

Pipe type automatic soil moisture monitoring station, also known as ultrasonic pipe type soil moisture monitoring station according to its working principle, is an ABS plastic pipe with built-in ultrasonic signal transmitter and wireless signal receiver. The ultrasonic generator emits high-frequency pulse signals at a frequency of 1GHz in the soil, and then reflects back to provide feedback signals. Due to the basic linear correspondence between the time difference of emission and reflection and the soil moisture content, the soil moisture content data is calculated based on this principle. According to this working principle, environmental factors such as soil salinity and acidity have little impact on testing accuracy. At the same time, it is resistant to external electromagnetic interference and can dynamically observe soil moisture and temperature data for different soil layers. Moreover, it enables fast, accurate, and comprehensive observation, allowing professional technicians to timely grasp soil moisture content and temperature.

The automatic soil moisture monitoring station adopts a layered observation structure, with one temperature observation point on the ground and one soil temperature and humidity measurement point at different depths below the surface of the underground soil according to user needs, to observe the soil temperature and humidity within the corresponding range.

4、 Installation Guide

4.1 Preparation work

4.1.1 Open box inspection

Check if the outer packaging is damaged; Open the box and check if the equipment and accessories are complete according to the equipment list.

Attention: Earth drills and solar panels are not included in the factory accessories of Zhishui. If you need them, you can purchase them separately.

4.1.2 Tool Preparation

Earth drill, purified water or tap water, basin, gloves (prepared according to personal needs)

4.2 Formal Installation

4.2.1 Installation location selection instructions (applicable to agricultural crops)

a. Install equipment after sowing crops;

b. The installation location is on a flat terrain;

c. Under comprehensive irrigation conditions, priority should be given to selecting areas with less water harvesting as monitoring locations; Under local irrigation conditions, select moist areas as monitoring locations;

d. Select locations where crop growth is balanced and can represent the majority of crop growth;

e. To understand the root distribution of the monitored crops, it is generally recommended to choose a location closer to the water absorbing roots of the crops.

f. Choose to build a station on a plot of land with strong signals such as GSM/GPRS that can accurately send data SMS messages normally

4.2.2 Drilling

a. After completing the soil sampling drill bit, handle, and support rod, place the soil sampling drill vertically on the ground, hold the handle tightly with both hands, and slowly rotate it clockwise. (Attention: Do not apply too much force, make sure to rotate slowly for a few more turns to prevent the drill bit from deviating and causing the hole to become crooked)

b. Remove the soil drill from the hole and place it in a basin. Use tools to collect the drilled soil into the basin for mixing with the mud. (Note: The first drilling soil will not be collected due to excessive impurities)

c. Repeatedly drilling and taking soil as mentioned above, and during this process, try to gently insert the sensor into the hole (do not forcefully touch the bottom of the device) to test whether the depth of the hole is appropriate; If there is any lag, use a soil drill to correct it and ensure that the sensor is smoothly inserted and removed; Until the hole depth is flush with the installation position marked by the sensor, the drilling is completed.

4.2.3 Mud and Mud

a. Pick out soil impurities such as stones, roots, and insoluble soil blocks from the pot. Grind the soil fine to mix with the mud.

b. Pour in an appropriate amount of water and stir thoroughly until viscous; Loam mud generally cannot be thicker than sesame paste; Complete with mud.

4.2.4 Grouting installation

a. Slowly pour the mud into the hole, about 1/2 of the hole position; It can be adjusted according to the actual situation.

b. Slowly insert the sensor into the hole, rotate it in one direction and press it down. If the speed is too fast, it may cause the bubbles to not be completely expelled. (Note: During the process of rotating and pressing down again, do not pull up the sensor to prevent gas from being sucked into the hole again)

c. After the sensor is installed at the correct depth, some mud will overflow around the equipment, and grouting is completed; At this point, the installation depth of the sensor is flush with the hole opening. (Note: Remove any excess mud beyond 3cm around the sensor to prevent clumping from affecting water infiltration)

4.2.5 Installing solar panels (users who do not require solar power supply panels do not need to perform this step)

a. Site selection for solar panels

The installation position of solar panels should be as far away from sensors as possible, generally 50cm away from the sensor, but should not exceed the length of the power cord. The panel of the solar power supply panel should face towards the direction of the sun, that is, south, and there should be no obstruction in front as much as possible.

The solar panel bracket can be inserted into the selected position using two methods: discrete pole type and tripod type.

b. Fixed solar panel

Fix the solar panel panel onto the bracket, align the four holes in the center of the panel with the four holes on the bracket, and then tighten them with screws.

c. Connect the solar power panel to the measuring instrument

Firstly, connect the wiring terminals on the panel and bracket together and screw them together;

Secondly, to connect the solar interface of the device, it is necessary to pull out the top cover of the device upwards. On the opposite side of the switch is the solar interface (aviation jack); Align the other end of the bracket power cord with the interface and insert it. Tighten the bolt to complete the installation of the solar panel.

4.2.6 Installation completed

After pulling out the top cover of the device upwards, press the power button to activate the device. It is recommended to resume normal work after the mud has returned to its normal state.

Other precautions:

1. Key points for sand installation

The installation steps for sandy soil are no different from those for loam soil. It is important to prepare sufficient water, not less than 5L. Before grouting, pour water into the hole and wet the entire wall until excess water appears at the bottom of the hole. Then, following the steps, slowly pour the mud into the hole, approximately at 1/2 position of the hole. The remaining installation steps can refer to the installation of loam soil.

2. Key points for clay installation

The installation of clay is carried out after drilling and collecting soil, cleaning impurities, and soaking the clay in water for more than 4 hours to soften it and facilitate the formation of a relatively uniform slurry. After soaking, stir until viscous, and then grout. The remaining installation steps can refer to the installation of loam soil.
