HT-1 Digital analog output soil temperature electronics digital temperature and humidity sensor

Specifications

HT-1 Digital analog output soil temperature electronics digital temperature and humidity sensor  

Feature

digital temperature and humidity sensor

•  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

digital temperature and humidity sensor

 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 digital temperature and humidity sensor

•  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.
