Frequency Domain Probe Design for High Frequency Sensing of Soil Moisture

Accurate moisture sensing is an important need for many research programs as well as in control of industrial processes. This paper describes the development of a high accuracy frequency domain sensing probe for use in obtaining dielectric measurements of materials suitable for work ranging from 300 MHz to 1 GHz. The probe was developed to accommodate a wide range of permittivity’s ranging from...

Developing Irrigation Conservation Strategies Using Soil Moisture Sensors and ET

Soil Moisture and Temperature sensor based intelligent irrigation water pump controlling system using PIC 16F72 Microcontroller

This paper aims in providing a user friendly, reliable and automated water pumping system. The paper aims in designing a system which is capable of detecting moisture level in the soil and capable of taking the decision of switching ON/OFF water pump. The system also uses temperature sensor to detect the temperature and automatically the fan speed can be controlled like coolants. In this paper ...

Estimation of soil moisture using optical, thermal and radar Remote Sensing )Case Study: South of Tehran(

Traditional methods of field measurement of soil moisture in addition to the difficulty, the need for manpower and money and fail to take place on a large scale to be able to show moisture. Therefore, remote sensing has become a widespread use .Landsat 8 satellite data and Sentinel-1 radar satellite from Tehran were provided. 72 soil samples were taken at the same time by satellite passing from...

A In-Situ Soil Moisture Sensing: Optimal Sensor Placement and Field Estimation

We study the problem of optimal sensor placement in the context of soil moisture sensing. We show that the soil moisture data possesses some unique features that can be used together with the commonly used Gaussian assumption to construct more scalable, robust and better performing placement algorithms. Specifically, there exists a coarse-grained monotonic ordering of locations in their soil mo...
