Overview
The Onset ECH2O 10HS soil moisture smart sensor measures a large 1-liter volume of soil, providing a more accurate picture of average soil moisture. The sensor integrates the field-proven 10HS Sensor and a 12-bit A/D, providing ±3% accuracy in most soil conditions and ±2% accuracy with soil-specific calibration.
Mechanics
The 10cm probes measure soil moisture over a larger volume of soil, helping to average out any soil variability. Readings are provided directly in volumetric water content. The sensor's high-frequency design minimizes salinity and textural effects and gives it a wide measurement range.
Measurement range in soil: 0 to 0.570 m³/m³ (volumetric water content)
Accuracy:
±0.033 m³/m³ (±3.3%) typical 0 to +50°C (+32° to +122°F) for mineral soils up to 10 dS/m
±0.020 m³/m³ (±2%) with soil specific calibration
Resolution: 0.0008 m³/m³ (0.08%)
Soil probe dimensions: 160 x 32 x 2 mm (6.5 x 1.25 x 0.08 in.)
Weight: 190 grams (6.7 oz)
Decagon probe part no.: 10HS
Sensor operating temperature:
0° to +50°C (+32° to +122°F). Although the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F) and the smart sensor tube (the white portion of the sensor cable that houses the electronics) can be exposed to temperatures up to +70°C (+158°F), the soil moisture data collected at these extreme temperatures is outside of the sensor's accurate measurement range. Extended temperatures above +50°C (+122°F) will decrease logger battery life when using for the S-SMD-M005 smart sensor.
Volume of influence: 1 liter (33.8 oz)
Sensor frequency: 70 MHz
Bits per sample: 12
Number of data channels: 1
Measurement averaging option: No
Cable length available: 5 m (16 ft)
Length of Smart Sensor network cable: 0.5 m (1.6 ft)

Cal Poly, San Luis Obispo Manages Monitoring Efforts in Morro Bay
California Polytechnic State University, San Luis Obispo (Cal Poly, SLO), has been monitoring Morro Bay for decades, and while the monitoring program has changed over the years, the dedication to monitoring the bay has remained the same. The project started in 2006 as a Packard Foundation-funded initiative to monitor water quality flowing in and out of Morro Bay. The goal at the time was to use the data collected to develop and inform an ecosystem-based management plan in collaboration with the Morro Bay National Estuary Program (MBNEP). Since the estuary was the focus at the time, researchers were monitoring water flowing into the estuary from Chorro Creek and Los Osos Creek.

Green Water in Green Bay: Using Data Buoys to Monitor the Southern Bay
While the bay of Green Bay has been referred to as the largest freshwater “estuary” in the world, the watershed hosts intensive agriculture and contributes one-third of Lake Michigan’s total phosphorus load. The Fox River flows into the bay, carrying excess nutrients largely the result of non-point source runoff from the watershed. With a history of deterioration extending well into the last century, the bay ecosystem suffered significant declines in water quality. This, in turn, stimulated major clean-up and ongoing restoration efforts to improve water quality. Tracking these changes is an important aspect of ecosystem management.

Cross-Border Sewage Contaminated Flows: Monitoring the Tijuana River
The Tijuana River runs across the US-Mexico boundary, flowing into and throughout southern California, carrying with it nutrients and contaminants throughout the estuary. In recent decades, the flows have been heavily polluted with untreated sewage from the City of Tijuana. The wastewater enters the greater Tijuana River estuary, impacting coastal communities and disrupting the natural environment. In order to better understand these cross-border flows, researchers out of San Diego University sought to monitor the waterway test the capabilities of in-situ sensors to measure the contaminated water. Natalie Mladenov and Trent Biggs were two of the researchers involved in the project, deploying a real-time monitoring system in May of 2021.
