Description：
The soil water potential sensor is a practical method to study soil water movement from the energy point of view. The soil water potential sensor is a practical instrument that reflects soil moisture and guides irrigation. The soil water tension measured by the soil water potential sensor is the suction force of the soil to water. The wetter the soil, the lower the suction power; otherwise, the greater the suction power. When the soil moisture increases until all voids are filled with water, the soil water tension will drop to zero.
Features：
(1) High-quality ceramic head: The ceramic head is the sensing part of the instrument and has many small pores. The sensitivity of the instrument depends on the penetration rate of the ceramic head. This method has the advantages of fast permeability, high sensitivity, and small error of the basic potential value.
(2) Smart chip: The soil water potential sensor uses a low-power single-chip high-quality operational amplifier to ensure the sensor’s low power consumption, high sensitivity, and stable signal transmission.
(3) Vacuum pressure gauge, side filling port, humanized design, convenient to check the water volume in the pressure gauge and replenish water in time.
Monitoring parameters：
The soil moisture sensor can reflect soil conditions in real time, measure the water absorption and irrigation indicators of field or potted soil, and monitor the dynamic changes of soil moisture (including soil moisture and groundwater). It can grasp the soil condition in real time through the remote platform, make the data into a table, and support the computer to receive remote cloud viewing data.
application：
Soil water potential sensors are widely used in agricultural planting, fruit base vineyards, intelligent planting and other places that need to detect soil moisture.
