Soil moisture sensor network design for hydrological applications

Wireless Sensor Network Based Soil Moisture Monitoring System Design

Soil moisture is the amount of water in the soil. It plays a crucial role for efficient photosynthesis, respiration, transpiration and transportation of minerals and other nutrients through the plant. Proper irrigation schedule is very critical to plant growth. This paper presents a soil moisture monitoring system which comprises of commercially available soil moisture sensor Decagon EC-5, low ...

A Reactive Soil Moisture Sensor Network: Design and Field Evaluation

Wireless sensor network technology has the potential to reveal finegrained, dynamic changes in monitored variables of an outdoor landscape. But there are significant problems to be overcome in order to realise this vision in working systems. This paper describes the design and implementation of a reactive, event driven network for environmental monitoring of soil moisture and evaluates its effe...

Hydrological downscaling of soil moisture

Design and performance of a wireless sensor network for catchment-scale snow and soil moisture measurements

[1] A wireless sensor network (WSN) was deployed as part of a water balance instrument cluster across a forested 1 km headwater catchment in the southern Sierra Nevada of California. The network, which integrates readings from over 300 sensors, provides spatially representative measurements of snow depth, solar radiation, relative humidity, soil moisture, and matric potential. The ability of th...

The International Soil Moisture Network - An observational network for soil moisture product validations

In situ soil moisture measurements are invaluable for calibrating and validating land surface models and satellite-based soil moisture retrievals. On a worldwide basis the number of meteorological networks measuring soil moisture is still limited and their data lack standardization of technique and protocol. In response to this, the International Soil Moisture Network (ISMN) was initiated to se...
