DS200 Stable resistant stainless steel digital rs485 humidity measuring instrument temperature sensor with high accuracy

 

 

 

 

 

 

 

Feature

•  High stability, easy installation and maintenance operations, ABS plastic. 
•  Sealing, buried in the soil for long-term use, from corrosion.
•  Soil moisture sensor output signals using a standard current loop transmission technology to anti-interference ability, transmission distance, high accuracy, fast response. 
•  High accuracy, wide range, variety of materials can be measured more, and faster response speed can be used to automate online monitoring

Priciple

 

Ht-1 type auto temperature sensor oem applying crystal oscillator produces high frequency signal, and transferred to the parallel metal probe, produce the superposition of the sending signal and the returned signal ,which can measuring the soil moisture content through measure the amplitude of the signal .Due to the dielectric constant of water is much larger than normal material, so when the soil moisture content increases, the dielectric constant will increases , so it can measure the soil moisture according to the corresponding relationship between soil dielectric constant and the soil moisture .

 

Application of the humidity meter

•  Soil moisture sensors are widely used in agricultural irrigation systems, soil moisture monitoring, hydrological monitoring and other aspects of water conservation, and the number of mining and its long distance transmission equipment which may constitute a telemetry system. 
•  For example, when the soil is arid, remote alarm system, while the control system automatically switch es the pump and valve control, to automate irrigation. 
•  When combined with some additional sensors, you can also calculate the evaporation of soil moisture and crop water needed parameters.

digital humidity measuring instruments

 

1.Can this sensor monitor both humidity and temperature of the soil?

YES,this sensor can monitor both the humidity and temperature of the soil.

 

2.What signal output it support?

For this humidity sensor,it support both analog and digital rs485 signal output,so it can be connected with pc or controller.

 

3.If this sensor support both humidity and temperature,how can I monitor both data?

If you want to monitor the humidity and temperature at same time,you can connect 2 signal output.
