Understand the patternFreshwater Sentinel • Remote water monitoring
A battery-powered sensor node and cellular dashboard bring water-quality trends into view. Built to help freshwater teams understand changing conditions and plan better follow-up.
Integrated prototype. Seeking partners for supervised field evaluation.
More context between samples
Periodic samples are essential. Freshwater Sentinel adds scheduled measurements between those visits, helping your team explore when conditions change and where a closer look could be useful.

Keep the site in viewMeet the system
The prototype brings sensing, internal battery power, cellular telemetry and a remote dashboard together. Sensor selection, sampling and installation are planned around the site and the questions you want to answer.

The pictured sensor package uses four probes for these five measurements. Sensor selection depends on your monitoring goals and wet or dry site conditions. Readings need calibration and field reference checks to establish accuracy at your site.
Scheduled acquisition from a sensor package matched to the site, powered by an internal battery.
Batched cellular delivery of readings and node-health information.
A remote dashboard for historical trends, data arrival and system status.
Start with your monitoring site
We're talking with park managers, freshwater monitoring teams, consultants and lake-management contractors about where more frequent measurements could help.
Tell us about your siteExplore trends between routine checks and add context around weather, treatment or other site events.
Explore monitoring at sites with continuous water or dry periods. Suitability depends on the sensor package, installation, cellular coverage and service access.
Evaluate remote measurements alongside your current sampling methods and the decisions your team already makes.
Current development stage
Freshwater Sentinel is an integrated prototype. We are seeking partners to define a supervised deployment and evaluate its usefulness alongside existing reference measurements.
of integrated bench operation
scheduled hourly sensor cycles recorded
Evaluate field accuracy, fouling, deployment durability and maintenance needs. The bench run demonstrates continuity; it does not establish field accuracy or maximum battery endurance.
First, we discuss your site and monitoring priorities. Then we agree on reference measurements, service access and what a successful evaluation would demonstrate. Scope and duration follow the site’s needs.
Practical questions
No. Freshwater Sentinel is being developed for supplemental monitoring and operational context. It does not replace required sampling, and field or regulatory suitability must be validated for the intended use.
Yes, with an appropriate sensor package. Dry-period operation and wet/dry transitions depend on the selected sensors and installation. We'll assess your site's conditions, sensor-care requirements and validation needs when planning a deployment. Water-quality measurements require suitable water contact for the selected probes.
The prototype uses an internal battery and cellular data connection. It does not require mains power or site Wi-Fi. Cellular coverage, sampling frequency and the service plan need to be assessed for each location.
We'll discuss your water body, current measurements and the gaps you'd like to understand. If there is a fit, we'll work through a supervised field-evaluation plan together. You do not need a finished specification to start the conversation.
