The TH301 soil water content monitoring system is mainly composed of a data logger and TH series of soil moisture sensors. The measurement data of multiple monitoring samples can be viewed and downloaded online in real time on a freely provided data management platform.
Data logger:
The
data logger is low-cost, low-power, multi-functional, which integrates solar
charge controller, polymer lithium battery, GPRS, GPS and true color touch
screen. The data can be downloaded from a mobile phone via bluetooth or
remotely wirelessly transmitted, and has an Android APP data viewing and
management tool. The edge of the case is sealed with an O-ring, which has good
water resistance and is convenient for monitoring in the field. Moreover, it
can connect various types of sensors and supports SDI-12 and RS-485 interfaces.
TH
series of soil moisture sensors:
TH series of soil moisture sensors have three types. TH-10 is to measure soil volumetric water content. TH-20 is to measure soil volumetric water content and temperature. TH-30 is to measure soil volumetric water content, temperature, and electrical conductivity.
TH-10 TH-20 TH-30
TH series of soil moisture sensors can directly measure the volumetric moisture content of soil by measuring the dielectric constant of the soil, which is a method of measuring soil moisture in accordance with current international standards. It is suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant cultivation, sewage treatment, precision agriculture and other occasions.
The sensor has the following characteristics:
The electrode adopts specially processed synthetic material, which can withstand strong external impact and is not easy to damage.
Excellent sealing, better than similar imported products, can be buried in the soil or directly into the water for long-term dynamic monitoring.
High precision, fast response, good interchangeability, probe insertion design ensures accurate measurement and reliable performance.
Perfect protection circuit and multiple signal output interfaces are optional.
IP68 waterproof interface.
