Soil Temperature Moisture Sensor 4-20mA/0-5V/RS485 Output IoT Agriculture

The soil temperature and moisture sensor is a high-precision, high-sensitivity soil moisture measuring instrument. The electromagnetic wave pulse emitted by the sensor is transmitted to the probe through the coaxial cable, and then enters the soil medium to measure the apparent dielectric constant of the soil, thereby obtaining the real water content of the soil. The influence of metal ions, etc. This instrument can be widely used in soil moisture monitoring, water-saving irrigation, greenhouses, grassland pastures, soil speed measurement and other fields.

Soil Temperature Moisture Sensor adopts the TDR principle, and reflects the soil water content by measuring the dielectric constant of the soil. The measured soil value is the soil moisture volume percentage, which is the current standard soil moisture measurement method.

Technical parameters of soil temperature and moisture sensor

The NBL-S-THR Soil Temperature and Moisture Sensor is a state-of-the-art instrument designed to accurately measure soil moisture, combining high accuracy with high sensitivity to ensure reliable data.

Working principle of NBL-S-THR soil temperature and moisture sensor:

Based on electromagnetic wave pulse technology: electromagnetic waves emitted by the sensor are transmitted through a coaxial cable to a probe, which introduces these pulses into the soil. In the soil, these pulses interact with the soil medium, and the sensor measures the soil's apparent dielectric constant - a physical quantity that is closely related to the soil's water content - by analyzing the returned signal. Thus, through this non-destructive method, the NBL-S-THR is able to accurately determine the true moisture content of the soil.

The strength of this sensor lies in its fast response and accuracy, while it also offers good stability and reliability for consistent performance under different environmental conditions. Notably, the NBL-S-THR is unaffected by changes in fertilizer composition or metal ion concentrations in the soil, which allows it to provide reliable data in a wide range of soil types.

In addition, the sensor is easy to install and use for a wide range of application scenarios, such as soil moisture monitoring in agriculture, water-saving irrigation systems, greenhouse and greenhouse management, maintenance of meadows and pastures, and soil snapshotting.

Whether in the field of scientific research or agricultural production practice, the NBL-S-THR soil temperature and moisture sensor is an indispensable tool to provide users with accurate soil moisture information, helping to achieve more scientific and rational water management and crop growth optimization.

NBL-S-THR Soil Temperature and Moisture Sensor Application Areas

The NBL-S-THR Soil Temperature and Moisture Sensor is suitable for a wide range of application scenarios related to soil moisture monitoring due to its high accuracy, high sensitivity and good adaptability to environmental factors. The following are some of the main application areas: 

1. Agriculture and Horticulture:

   - Water Saving Irrigation: by accurately measuring the moisture content of the soil, irrigation schemes can be optimized to reduce water wastage and increase crop yields.

   - Greenhouse management: In a greenhouse environment, maintaining proper soil moisture is critical for plant growth. The sensor helps the automatic control system to adjust the watering frequency and amount according to actual needs.

 2. Environmental monitoring:

   - Soil moisture monitoring: is used to assess the moisture status of the land, which is important for understanding drought conditions in the region, planning water management and protecting the ecosystem.

   - Grassland Pasture Management: To ensure that grassland has sufficient moisture to support the growth of pasture grasses, while avoiding waste of resources and environmental pollution caused by over-irrigation.

 3. Research and Education:

   - Soil research: provide scientists with accurate data to study soil properties, hydrological cycles and the effects of climate change on soil.

   - Teaching experiments: as a teaching tool to help students understand the principles of soil physics and learn how to make soil moisture measurements using modern technology.

 4. Urban Greening and Landscaping:

   - Parks and Golf Courses: maintain the aesthetics of green spaces while rationally controlling the amount of watering, saving costs and protecting the environment.

   - Home gardening: help enthusiasts take better care of their garden or balcony plants and make sure they are properly supplied with water.

 5. Engineering and Construction:

   - Slope Stability and Foundation Settlement Monitoring: understanding changes in soil moisture content can help predict potential geologic risks such as landslides or soil movement under building foundations.

 6. Ecological restoration projects:

   - During the rehabilitation of degraded land, monitoring soil moisture is one of the key steps to ensure successful vegetation recovery.

 In conclusion, the NBL-S-THR Soil Temperature and Moisture Sensor plays an important role in the above and any other areas where accurate soil moisture information is needed, thanks to its fast and accurate nature, which is not affected by soil composition.
