Calibration of a Capacitance Soil Sensor Required to Achieve the Level of Accuracy Required for Satellite Ground Truthing

This study published in American Meteorological Society’s BAMS journal demonstrates the extent of variability in readings one can expect with a soil moisture sensor based on capacitance technology. To obtain the highest level of accuracy that is required for remote sensing applications, capacitance-based soil sensors often need to be recalibrated. The HydraProbe is an impedance-based …

Free Software Lets You Use HydraProbe to Determine Soil Water Retention Curve

The Soil Water Characteristics software is a hydraulic properties calculator, developed by the US Department of Agriculture and Washington State University. It estimates soil water tension, conductivity and water holding capability based on the soil texture, organic matter, gravel content, salinity, and compaction. The Soil Water Characteristics software is a hydraulic properties calculator, developed by …

Using the HydraProbe Soil Sensor for Determination of Flood Risk in the New York State Mesonet

In January 2014, the Department of Homeland Security established the New York State Early Warning Weather Detection System. The centerpiece of the system is the New York State Mesonet, a network of 125 weather stations across the state, with at least one site in every county. Each site measures temperature, humidity, wind speed and direction, …

HydraProbe selected to be used in Canada’s RISMA Network for Agricultural Monitoring

A new study published in the Soil Science Society of America Journal investigated the field performance of 5 soil moisture instruments in heavy clay soils. The HydraProbe outperformed TDR and capacitance-based soil sensors in terms of stability and accuracy in Manitoba’s agricultural soil. Much of soil in the Canadian Prairie farmland is vertisolic. A new …

Dial-up, Push, Pull, Scheduled or On-Demand: The flexibility of M2M

Stevens M2M remote communications products (Cell-Net and eTracker) offer lots of flexibility for getting your data from a remote site. And don’t forget that reconfiguring how and when data is sent can be done anytime, from any device using the web-based interface. Multiple ways to trigger a transmission: transmit data based on schedule, or triggered …

How to Add a Secondary Telemetry to Your GOES Station

GOES, for all it’s no-cost, reliable virtues, has some drawbacks. First, it’s a one-way transmission—there’s no way of sending any data to your station. This means there’s no way to reprogram a data logger or reboot a stuck data logger or purge a bubbler without (an unplanned) visit to the site. The Stevens SatCom GOES …
