netH₂O Smart Buoy for Inspection & Emergency Response
Rapid-deployment water-quality monitoring for inspection and emergency response, from the netH₂O B770 buoy.
The netH₂O B770 is purpose-built for periodic inspection of remote or difficult-to-access water bodies, and for rapid-response environmental assessment during incidents and construction works. Complete with sensors, on-board logging, and 4G/LTE telemetry in a single integrated package, it can be deployed by non-specialist staff — cutting cost while enabling far more frequent monitoring than manual sampling allows.
A power-gated, duty-cycled architecture gives up to 12 months of unattended autonomy on a single charge — long enough to cover an entire inspection programme or construction season without a battery swap.
Periodic Monitoring of Remote Sites
Many agencies must monitor water quality at remote locations on a fixed schedule — lakes, reservoirs, rivers, coastal sites, or wetlands far from staff and facilities. Manual sampling is costly, infrequent, and weather-dependent.
- Simple deployment: place the buoy and go — no technical expertise required
- Autonomous operation: measurements on a programmed, OTA-reconfigurable schedule
- Automatic upload: results reach the office over 4G/LTE without a site visit
- More frequent data, lower cost: continuous coverage replaces sparse spot-checks
Ideal for environmental agencies, water utilities, research institutions, and any organisation monitoring multiple remote sites.
Construction & Dredging Compliance
Temporary works — piers, cable-laying, dredging, outfalls — usually carry a turbidity-impact monitoring condition in the environmental permit. The B770 is well suited to the standard near-source / mid-field / far-field array used for sediment-plume compliance:
- Turbidity: TriOS TTurb, ISO 7027 nephelometric (90° NIR scatter), for ambient baseline and construction-plume excursions
- Impact attribution: a near-source station captures the works, a far-field station holds the reference baseline
- Threshold alarms: immediate alerting when a reading exceeds the permitted limit
- Audit-ready records: timestamped, geo-referenced logs for the regulator
Emergency Response & Incident Monitoring
Environmental incidents demand immediate, continuous assessment. The B770 can be on station and reporting within minutes of arrival:
- Harmful algal blooms: chlorophyll-a (TriOS nanoFlu) to map and track bloom extent; dissolved oxygen to flag fish-kill risk
- Fish kills & ecosystem events: dissolved oxygen, temperature, and turbidity to help identify causes and document recovery
- Discharge incidents: conductivity/salinity and turbidity to track plume dispersion and concentration
- Real-time situational data for incident commanders, without keeping crews on site
Hydrocarbon / oil-spill sensing is available as a custom configuration on request.
Post-Disaster Water-Quality Assessment
After floods, storms, or other events, rapid assessment is essential — exactly when infrastructure and power may be down. The B770 is self-contained and battery-powered, so it works where mains and networks have failed.
- Source-water safety: assess contamination after flooding
- Recreation safety: turbidity and water-quality indicators for closure decisions
- Infrastructure damage: detect releases from damaged facilities
- Recovery tracking: document environmental recovery over time
Event-Triggered Alerting — the Difference for Incidents
The B770 doesn’t just log on a schedule. Its event-triggered burst transmission sends an immediate upload the moment any reading crosses a configurable threshold — so a turbidity spike or an oxygen crash reaches your team within minutes, not at the next scheduled report. Between events, the buoy stays in a low-power duty cycle: frequent measurement during working hours, slower cadence overnight, a single batched upload per day, and instant bursts only when something matters. That is what lets one charge cover up to a year while still catching the incident the instant it happens.
Data, Telemetry & Deployment
- Telemetry: 4G/LTE cellular — scheduled daily batch upload plus event-triggered bursts
- On-board logging: full local record retained even through a connectivity gap
- Sensors (TriOS application packs): turbidity, dissolved oxygen, conductivity/salinity, chlorophyll-a — choose per site; temperature included
- Autonomy: power-gated duty cycling, up to 12 months on a single charge; field-swappable battery
- Data delivery: REST API, a hosted dashboard, and CSV export — your data stays yours
- Deployment: operational within minutes of arrival; no specialist crew, no mains power
