Product Details
ZL6 Soil Moisture Monitoring System
ZL6 Soil Moisture Monitoring Systemis caused byMETERA monitoring system composed of a data collector, soil moisture sensor, and soil water potential sensor. Flexible and diverse configuration methods, easy installation, and convenient use. Widely used in the agricultural and forestry ecological industry, even in areas such as the Qinghai Tibet PlateauharshenvironmentThe operation still works well.
The soil moisture sensor developed by METER company adopts new technology and durable materials, with high measurement accuracy and cost-effectiveness. This sensor can continuously monitor the moisture content of multiple plots and different soil depths for a long time.The soil moisture sensor calculates the soil volumetric moisture content by measuring the dielectric constant of the soil. It is one of the sensors with relatively low sensitivity to soil salinity and temperature effects, and consumes fewer electrodesThis makes it easier to achieve long-term monitoring. Meanwhile, high resolution enables it toAccurately measure daily or even hourly water use efficiency.
METER company can integrate soil water potential sensors into this system, includingTEROS 21Soil water potential sensor andTEROS 32 field high-precision soil water potential and temperature tensiometer. Two types of sensors are suitable for monitoring soil water potential at the dry and wet ends, respectively.
The system adopts ZL6Cloud data collector, equipped with6The channel is the core component of this system.ZL6can be paired withMETERConnect any type of sensor. The operation is very simple, plug and play, and can be placed in the wild for a long time. Very low power consumption, supports solar charging. passGPRSConnect to the cloud server throughZentra Cloud enables remote monitoring of devices, management of data, and setup of instruments.
working principle
The soil moisture sensor is a dielectric type sensor that measures the dielectric constant or permittivity of the inserted medium by measuring the change in capacitance on the sensor. Another type of dielectric sensor TDRTime domain reflectometry is limited in its widespread use due to its high cost and complexity. Due to the very high dielectric constant of water, when the moisture content in the soil changes, the dielectric constant of the soil also undergoes significant changes.METERThe soil moisture sensor circuit can reduce the impact of temperature changes on measurementVery low.
The TEROS 21 sensor consists of a humidity sensor and a porous material with a known moisture release curve. When the porous material reaches moisture equilibrium with the surrounding soil, the humidity sensor measures the moisture content of the porous material and converts it into water potential based on the moisture release curve.
The TEROS 32 tensiometer can transmit soil water potential to the inside of the sensor through a ceramic cup, causing changes in water pressure inside the sensor. The pressure sensor located inside the sensor senses the signal output pressure changes and obtains the corresponding water potential.
