About Soil Water Potential Sensor

Soil water potential refers to the amount of work (or energy) required to transfer a unit quantity of pure water from a reference state—typically defined as pure water at atmospheric pressure, at a temperature of 25°C, and at the same elevation as the soil water—to a specific point within the soil under isothermal and isobaric conditions.

How to install soil water potential sensor?

1. Preparation before installation

  • Inspect the sensor: check the soil water potential sensor and its accessories to ensure all components are complete and undamaged.
  • Prepare tools: gather necessary tools such as a soil auger, shovel, and water (for moistening the soil or preparing slurry).
  • Determine installation location: choose an appropriate installation site based on user requirements, typically near the root zone where plants absorb water. Determine the installation depth based on soil type and measurement needs, generally 30 cm or deeper.

2. Sensor installation

  • Digging: use a shovel or other tool to dig a hole of suitable depth at the chosen location.
  • Placing the sensor: prepare a soil slurry using some of the excavated soil and water, or moisten the soil directly. Coat the sensor with the wet soil or slurry and insert it into the hole. For deeper installations, slowly lower the sensor into the hole and gradually pour in the prepared slurry to ensure full contact between the sensing surface and the surrounding soil.

3. Connection and testing

  • Wiring: connect the sensor’s cable to the data acquisition device, ensuring a secure and stable connection.
  • Testing: before backfilling, test the sensor using the data logger to confirm proper operation and accurate data transmission.

4. Backfilling and protection

  • Backfill soil: once the sensor is confirmed to be working properly, backfill the hole with the remaining soil and compact it to restore the soil to its original state. This ensures close contact between the sensor and the surrounding soil for optimal measurement accuracy.

FAQs - LoRa Soil Moisture Sensor

1. What is soil water potential?

Soil water potential refers to the potential energy of water within the soil, defined as the amount of energy required to extract a unit of water from the soil under isothermal conditions. It is typically measured in kilopascals (kPa). When the soil is fully saturated with water, the water potential is zero. As the soil dries and the water content drops below saturation, the water potential becomes negative—the drier the soil, the more negative the value.

Soil water potential is a key parameter for assessing soil drought conditions and plays a crucial role in plant water stress research.

2. What is a soil water potential sensor?

A soil water potential sensor is a device used to measure the strength with which water is retained in the soil—that is, how easily or difficultly plants can absorb water. Unlike soil moisture sensors, which measure the quantity of water in the soil, soil water potential sensors measure the energy state of the water. This provides more meaningful insights into plant-available water and is especially useful for irrigation management, plant physiology studies, and drought monitoring.

3. How does a soil water potential sensor work?

A soil water potential sensor typically consists of a humidity sensor and a porous material with a known water release curve. When the porous material reaches moisture equilibrium with the surrounding soil, the humidity sensor measures the moisture content within the porous material. Using the known water release curve, the sensor then converts this moisture content into a corresponding soil water potential value.

This indirect method allows the sensor to accurately reflect the energy status of water in the soil, providing valuable data for evaluating plant water availability and optimizing irrigation practices.

4. What is the effect of soil water potential on soil?

Relationship between soil water potential and soil:

Water potential range (kPa)Soil stateDescrição
0 ~ -10SaturatedThe soil is too wet and the drainage may be poor
-10 ~ -30Field holding capacityBest for plant growth
-30 ~ -100Gradually dryPlants begin to be limited by water
Below -100DroughtPlants are seriously lacking water and may even wither
5. How to wire the sensor?

Brown wire: Connect to power supply positive (10–30V DC)
Black wire: Connect to power supply negative
Yellow wire: Connect to RS485 A (Data A)
Blue wire: Connect to RS485 B (Data B)

6. What are the applications for a soil water potential sensor?

Soil water potential sensors are widely used in smart agriculture, water resource management, scientific research, greenhouse automation, orchard irrigation, and forest ecology. They help improve irrigation efficiency, optimize water usage, and increase crop yields by providing precise data on soil water availability.

7. What should be noted during installation?
  • Ensure the sensor maintains firm contact with the surrounding soil
  • Avoid interference from rocks, air gaps, or loose soil
  • It is recommended to insert the sensor vertically at a representative location
  • Keep the installation depth consistent across measurement points to ensure reliable data comparison
