TELEMETRY QUALITY ASSURANCE

Sensor & Data Confidence API — Telemetry QA, anomaly detection & coverage screening.

Real-time screening for stale telemetry packets, ultrasonic bounce anomalies, rapid jump artifacts, and spatial rainfall radar blind spots before inputs reach sirens, downstream digital twins, or emergency dashboards.

THE DECISION IT SUPPORTS

Can we trust this river sensor reading before activating warning sirens?

River sensors face battery drops, debris entanglement, turbulent surface reflections, and transmission lag. This API evaluates reading freshness, physical rate-of-change plausibility, acoustic signal-to-noise ratio, and neighboring gauge consistency to assign each sensor a confidence tier.

Built for

  • River sensor network operators
  • Catchment flood warning authorities
  • Hydrological digital twin platforms
  • Municipal flood defense & siren controllers

WHY TEAMS USE IT

Turn broad data into a clearer next step.

Each result is designed to narrow a decision, show the inputs behind it, and surface what must still be checked locally.

01

Prevent false siren alarms

Filter out ultrasonic bounce artifacts and debris snag spikes before they trigger municipal alarms.

02

Automate sensor maintenance dispatch

Flag sensors with decaying battery voltages, weak SNR, or stale packet transmissions.

03

Spatial cross-validation

Compare paired upstream-downstream gauges to detect unphysical water level discrepancies.

04

Data integrity guarantee

Provide a single machine-readable confidence tier (trusted, degraded, anomaly) for every telemetry stream.

FROM REGION TO FIELD

Images illustrate the operational setting. They are not live observations; use source timestamps and local measurements for decisions.

Flag stale packets exceeded 45 minutesTELEMETRY FRESHNESS

Flag stale packets exceeded 45 minutes

Prevents sirens from sounding or emergency gates from moving based on out-of-date telemetry.

Catch acoustic jumps and debris snaggingANOMALY DETECTION

Catch acoustic jumps and debris snagging

Isolates sudden jump artifacts caused by sensor turbulence, acoustic surface bounce, or snagged debris.

Verify precipitation radar beam coverageRADAR COVERAGE SCREENING

Verify precipitation radar beam coverage

Flags terrain blockages where radar underestimates rainfall in deep mountain headwaters.

THE INFORMATION STACK

What goes in—and what it helps explain.

Availability is stated per input. AtmosGrid never converts a missing parcel observation into a made-up field value.

A PRACTICAL WORKFLOW

From input to reviewable decision.

The workflow keeps model context, field evidence and human approval in their proper places.

  1. 01

    Ingest raw sensor telemetry

    Receive raw water level, flow velocity, and diagnostic packets from field sensors.

  2. 02

    Evaluate temporal freshness

    Flag any station where data packets are older than the 45-minute operational limit.

  3. 03

    Run physical plausibility tests

    Check for ultrasonic jumps (>0.5m in 5 min), flatline freezes, or signal-to-noise degradation.

  4. 04

    Output sensor confidence tier

    Return clear confidence classifications (trusted, warning, degraded, rejected) to downstream systems.

HOW INFORMATION BECOMES USEFUL

Examples of decisions it can inform.

These are screening patterns, not automatic instructions. Operational thresholds and local advisories remain authoritative.

SCENARIO 01

Sudden 0.7m level jump in 5 minutes with zero upstream rainfall

Signal
Acoustic jump anomaly flag raised; SNR drops to 11 dB (likely turbulence or floating debris).
Useful action
Suppress siren activation; quarantine reading and apply 3-ping temporal persistence filter.
Check before acting
If upstream gauge also surges, jump may represent an actual dam release or flash wave.
SCENARIO 02

River gauge battery falls below 11.0V during multi-day overcast storm

Signal
Battery status flag "LOW_VOLTAGE_DEGRADED"; telemetry age rises to 52 minutes.
Useful action
Mark gauge as degraded; switch downstream digital twin to tributary rainfall proxy.
Check before acting
Dispatch maintenance technician once water levels subside.
SCENARIO 03

All sensors reporting with fresh packets and nominal SNR

Signal
Network data integrity is 100%; zero anomalies detected across all catchment gauges.
Useful action
Pass telemetry directly to real-time flood warning dashboard with high-confidence badge.
Check before acting
Routine calibration checks recommended every 90 days.

A transparent API contract.

The response exposes gaps and limitations so an application can explain confidence instead of hiding it.

CAPABILITY BOUNDARIES

Useful now. Honest about what comes next.

Supported now

  • Packet freshness and staleness screening (flagged at >45 min)
  • Ultrasonic & radar jump anomaly detection
  • Battery voltage, signal-to-noise ratio, and hardware health scoring
  • Rainfall radar coverage and beam blockage diagnostics

Additional data required

  • Raw sensor diagnostics (battery, SNR) if hardware scoring is required
  • Paired sensor topology for spatial cross-validation

BUILD RESPONSIBLY

Use the result to focus attention—not replace field judgment.
