MiProbE Sentry -- Real-time Microbial Sensor Technology

The MiProbE™ Sentry Microbial Sensor is our newly developed proprietary microbial sensor probe technology.

The sensor probe is combined with a Microbial Signal Processor™ and cloud-based analytics platform to monitor in real-time the microbial biofilm response to process changes in single and multi-stage aerobic or anaerobic bioreactor processes.

The technology also works in situations where biofilm sensor fouling prevents reliable ORP (Oxygen Reduction Potential) or DO (Dissolved Oxygen) sensor readings, and can work alone or in conjunction with these other sensors for process optimization. The MiProbE Sentry itself requires no regular maintenance or cleaning -- the biofilm is the active surface for the sensor probe.

The technology is currently being used for process monitoring and control in large-scale wastewater treatment, industrial-scale fish farming and remote environmental subsurface monitoring applications. Preliminary algae process monitoring testing is being conducted in conjunction with Arizona State University. Contact us for inquiries about becoming a product development partner in your industry.

MiProbE Sentry Core Features

Remote Automated Monitoring

The automated MiProbE™Sentry is a solar-powered, cloud-based, complete microbial sensor system with minimum setup and continuous process monitoring in any environment.

Rugged & Reliable

These rugged systems can be installed in-situ for both remote lagoon & pond monitoring or at high-throughput industrial facilities with minimal setup costs. Each Sentry comes with a 5-watt Solar Panel and heavy-duty backup battery.


Each Microbial Signal Processor System Board supports up to three MiProbE Sentry sensors, up to three Temperature Sensors, and up to two 4-20 mA sensors for specific needs.

Built-in Cellular &Cloud Connectivity

Each system is provisioned with its own cellular modem and configured to upload to our cloud analytics platform for easy data access.

MiProbE Sentry Operating Specifications

MiProbE Sentry for Wastewater Treatment Applications

Direct Deployment

No 'Proxy' Measurements

Direct Data that Avoids Expensive Lab Analyses

The automated MiProbE Sentry can be deployed for directly monitoring microbial processes in wastewater treatment plants from simple aeration ditches to activated sludge tanks and settling basins.

The MiProbE directly reports microbial response to the process conditions rather than proxy measurements such as changes in the environment (e.g., Dissolved Oxygen, pH, or Oxygen Reduction Potential). The MiProbE requires no regular maintenance or cleaning – the biofilm is the active surface of the sensor probe.

No bio-fouling, no reference cell replacements. Direct microbial responses without expensive lab analyses or single-use bioassay kits. Instant real-time data from any bioreactor process.

Actionable Data in Real-Time
- Setup Monitoring Alerts to know when changes have taken place.
- Track contamination impacts to microbial treatment processes and stages.
- Optimize processes by monitoring microbial response to system changes (e.g., DO concentration).
- Know what the microbes are doing, not just that the environment has changed.
- Low variance microbial signal without needing complex data filtration and manipulation.
