Description：
Soil water potential sensor is a practical method to study soil water movement from the perspective of energy. Soil water potential sensor is a very practical instrument to reflect soil moisture and guide irrigation. The soil water tension measured by soil water potential sensor is the suction of soil to water.The wetter the soil is, the smaller the suction is; otherwise, the greater the suction is. When the soil moisture increases to the point where all the 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, with many small pores. The sensitivity of the instrument depends on the water permeability (seepage) speed of the ceramic head. It has the advantages of fast water permeability , high sensitivity and small error of basic potential value.
(2)Intelligent chip: the soil water potential sensor uses low-power MCU high-quality operational amplifier to ensure low-power consumption, high sensitivity, stable signal transmission and other functions of the sensor.
(3)Vacuum pressure gauge, side irrigation port, user-friendly design, convenient to check the amount of water in the tensiometer, replenish water in time.
Monitoring parameters：
The soil water potential sensor can reflect the soil condition in real time and measure the soil water suction and irrigation index in field or pot. Monitoring the dynamic changes of soil water, including soil water and groundwater. It can grasp the soil condition in real time through the remote platform, tabulate the data, and support the computer to receive the remote cloud to view the data.
application：
Soil water potential sensor is widely used in agricultural planting, fruit base vineyard, intelligent planting and other places where soil moisture needs to be detected.
