Fathom

Problem

Surface water quality shifts faster than monthly lab schedules can capture. Fathom deploys IoT probes for temperature, turbidity, dissolved oxygen, and related markers so environmental teams see trends before thresholds are breached.

What it covers

• Multi-sensor probe head with field-swappable cartridges
• Edge buffering when uplink is intermittent
• Threshold alerts for DO, pH, and turbidity bands
• Time-series export for agency reporting

WaterSample readSurfaceProbe() {
  return {
    .tempC = probe.temp(),
    .ph = probe.ph(),
    .turbidityNtu = probe.turbidity(),
    .doMgL = probe.dissolvedOxygen(),
    .at = rtc.unix(),
  };
}
