Soil dryness sensor

NBL-S-THR High Precision Soil Temperature and Humidity Integrated Sensor

Soil dryness sensor product overview

NBL-S-THR Soil dryness sensor is a high-precision and high-sensitivity measuring instrument designed for agriculture, horticulture, environmental monitoring and other fields. It adopts advanced electromagnetic wave pulse technology to accurately and quickly obtain the real moisture content and temperature data of soil by measuring the apparent dielectric constant of soil. This sensor not only provides users with comprehensive soil environment information, but also supports a variety of output forms, which is easy to be integrated into a variety of monitoring systems, and is an ideal choice for realizing smart agriculture and green life.

Soil drying sensor technical parameters

Soil drying sensing working principle

The NBL-S-THR works by transmitting electromagnetic wave pulses, which are transmitted to the probe via a coaxial cable and then into the soil medium. The sensor measures the apparent dielectric constant of the soil and uses a specific algorithm to calculate the true moisture content of the soil. At the same time, the built-in temperature sensor acquires soil temperature data in real time, ensuring that the user receives comprehensive information about the soil environment.

Soil drying sensor product highlights

1. Precise monitoring:

   - High accuracy: electromagnetic wave pulse technology is used to ensure high data accuracy (±3%), wide temperature measurement range and high accuracy (±0.5℃).

   - Fast response: fast measurement speed, real-time reflection of soil moisture and temperature changes.   

2. Wide compatibility:

   - Multiple output forms: support RS485 communication, as well as current 4-20mA and voltage 0-5V output, easily integrated into various monitoring systems.   

3. Harsh environment adaptation:

   - Wide temperature operation: can work stably in the temperature range of -40℃ to 80℃, protection grade IP68, no fear of wind and rain, suitable for long-term outdoor use.   

4. low energy consumption design:

   - Energy-saving and environmentally friendly: only DC 12-24V power supply, product power consumption of about 0.3W, reducing long-term use costs.   

5. Multi-functional applications:

   - Comprehensive monitoring: not only monitor soil moisture, but also provide temperature data, applicable to farmland, greenhouse, garden, pasture and other multi-scenarios.

Soil dry sensing application scenarios in detail

1. intelligent agriculture:

   - Precision irrigation: deployed in farmland, through real-time monitoring of soil moisture, automatically triggering the irrigation system to realize on-demand irrigation, which saves water and promotes the healthy growth of crops.

   - Crop management: In greenhouses, sensors help regulate appropriate soil moisture to optimize the growing environment of crops and improve yield and quality.

2. Horticulture and landscape maintenance:

   - Personalized Maintenance: Plants in home gardens or public landscapes can be customized with watering schedules using the sensor to ensure that each plant receives just the right amount of water.

3. Environmental research and protection:

   - Ecological monitoring: used in nature reserves or research projects to monitor soil moisture changes over time and assess the impact of climate change on ecosystems.

4. Urban greening and lawn management:

   - Efficient Water Management: Installed on large lawns such as parks and golf courses to ensure efficient use of water and maintain lawns in optimal condition.

Soil drying sensing integration into existing irrigation systems

1. Data acquisition and transmission:

   - Sensors are installed near the crop's root layer to ensure that they accurately reflect the soil moisture in that layer. The sensor transmits data in real time to a control center or smart irrigation controller via RS485 or current/voltage output.

2. Intelligent control unit:

   - Irrigation systems require an intelligent control unit capable of receiving sensor data and making automatic decisions based on preset thresholds or algorithms. These algorithms may be based on a combination of factors such as soil moisture content, plant water requirements, weather forecasts, etc.

3. Automated response:

   - The control unit automatically starts the irrigation system when the soil moisture is lower than the set threshold; when the soil reaches the appropriate humidity, it is automatically turned off to realize precise irrigation.

4. Software integration:

   - Modern irrigation systems are often equipped with software interfaces that allow users to remotely monitor and adjust irrigation parameters, and sensor data is displayed directly in the software for easy management.

Soil drying sensing adapted to different types of soil

1. Calibration and calibration:

   - Different soil types (e.g. sandy, loamy, clay) have different dielectric constants that affect sensor readings. Therefore, sensors need to be calibrated for specific soil types before use to ensure measurement accuracy.

2. Multi-point monitoring:

   - Multiple sensors are installed in different soil types or different areas of the same plot to improve the representativeness and accuracy of the overall monitoring by weighted averaging of data.

3. Algorithm adjustment:

   - Develop or adjust algorithms to account for the effects of soil texture on water uptake and retention capacity to ensure that irrigation decisions are consistent with the water demand characteristics of different soils.

4. depth configuration:

   - Soil dryness varies with depth, and sensors should be installed at depths that best reflect the crop's water needs, based on crop root distribution and soil characteristics.

5. Long-term adaptability:

   - In long-term use, soil physical properties may change due to tillage, fertilization and other factors, recalibrate the sensor periodically to maintain the accuracy of the measurement.
