Tubular soil moisture monitor

1. Product Overview of Tubular Soil Moisture Monitor
The Tubular Soil Moisture Monitor is also known as the Tubular Automatic Soil Moisture Monitor and the Automatic Soil Moisture Monitoring System . The Tubular Soil Moisture Monitor is a multi-depth automatic soil moisture monitor that can Directly measures moisture and temperature in the soil, and can monitor five layers of soil at the same time. The tubular soil moisture monitor is a sensor developed based on the principle of dielectric constant, which can quickly, accurately and comprehensively monitor the moisture and temperature content of different soil layers. The number of monitoring layers of this sensor can be customized. It can measure the soil temperature and humidity of a minimum of three layers and a maximum of ten layers of soil.
This product can quickly and comprehensively understand soil moisture information, provide decision support for drought relief, and minimize disaster losses. The product uses standard Modbus-RTU485 communication, which can communicate up to 2000 meters and supports secondary development.
The products are suitable for agricultural and rural bureaus, universities, scientific research institutes, water conservancy bureaus, environmental protection bureaus, enterprises and institutions.

2. Product features of the tubular soil moisture monitor
1. The outer shell is made of PVC plastic pipe, and the interior emits high-frequency detection waves of nearly 1G Hz, which can penetrate the plastic pipe and effectively sense the soil environment.
2. It is not affected by salt ions in the soil. Agricultural activities such as chemical fertilizers, pesticides, and irrigation will not affect the measurement results, and the data is accurate.
3. The electrodes of the sensor are not in direct contact with the soil to avoid electrical interference on the soil and plants in the soil.
4. The product adopts the standard Modbus-RTU485 communication mode, with a maximum communication distance of 2000 meters.
5. Supports 10-30V wide voltage charging.
6. The integrated device can monitor five layers of soil temperature and humidity at the same time.

4. Tubular soil moisture monitor equipment installation instructions
1. Use a soil drill to drill holes at the appropriate location.
1.1 Hold the soil drill vertically on the ground, hold the handle tightly with both hands, press down and turn clockwise at a slow speed. (Note: Do not use too much force, and be sure to turn it slowly and several times to prevent the drill bit from wandering and causing the hole to become crooked.)
1.2. Take out the soil drill from the hole, put it into a bucket, and collect the soil in the drill into the bucket. Next step and mud. (Note: The first drilled soil will not be collected because there are too many impurities)
1.3. Repeat the above-mentioned drilling and soil extraction, and during this process, try to gently put the sensor into the hole (do not touch the device with force) bottom) to test whether the depth of the hole is appropriate; if there is any jamming, use a soil drill to correct it to ensure that the sensor is put in and taken out smoothly; until the hole depth is flush with the installation position marked by the sensor, the drilling is completed 2
. Making mud
2.1 Pick out the impurities in the soil removed by the soil auger, such as stones, grass roots, and soil clods that are not easily dissolved. Rub the soil finely so that
it can be mixed with the mud 2.2. Pour in an appropriate amount of water and stir thoroughly until it becomes viscous; the loam mud should generally not be thicker than "tahini"; and the mud is completed
3. Grouting installation
3.1 Slowly pour the mud into the hole, approximately to the hole 1/2 position; it can be increased or decreased according to the actual situation.
3.2 Slowly put the sensor into the hole, slowly turn it in one direction and press down. If the speed is too fast, the bubbles may not be completely discharged (note: turn it again Do not pull up the sensor during the pressing process to prevent gas from being sucked into the hole again)
3.3 When the sensor is installed to the correct depth, some mud will overflow around the equipment and the grouting is completed; at this time, the installation depth of the sensor is consistent with the hole (note: install the sensor around the hole) Remove excess mud beyond 3CM to prevent caking and affecting water penetration)
