The soil water potential sensor is a practical method to study soil water movement from an energy perspective. Soil water potential sensor is a very practical instrument to reflect soil moisture and guide irrigation. The soil water tension measured by the soil water potential sensor is the suction force of the soil on water. The wetter the soil, the less suction; otherwise the greater the suction. When soil moisture increases to the point where all voids are filled with water, soil moisture tension will drop to zero.
(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.
