Flood Monitoring & Early Warning Solutions

A low-cost, easy-to-install and easy-to-maintain early warning system for flood-prone communities and river basin management. Radar water-level sensing + rainfall monitoring + acoustic/visual alarms + solar power + 4G/LoRa auto-switching deliver warnings 6–12 hours ahead — and keep running in remote areas with no signal and no grid power.

Provides early warning with a lead time of 6–12 hours

Maintains operation under no-signal conditions

Supports off-grid operation without utility power

What Is Flood Monitoring & Early Warning?

Sensors and hydrometeorological instruments collect real-time water level, flow, rainfall and soil-moisture data across the basin. Combined with hydrological models, the system predicts when floods will occur, their peak levels and inundation extent — then pushes early warnings to riverside communities and authorities in time for evacuation, cutting loss of life and property.

How It Works / System Architecture

Sensor → RTU → 4G/LoRa → Platform → Alarm

① Data acquisition

Radar water-level gauge · tipping-bucket rain gauge

② Edge computing

RTU aggregates · caches during outagee

③ Remote transmission

4G / LoRa / Starlink

④ Platform analysis

Threshold triggers · multi-level warning

⑤ Warning broadcast

Local-language sound & light

Radar water-level gauges and tipping-bucket rain gauges collect data 24/7 in the field;
RTU / data collectors aggregate the data, cache it locally during outages, and auto-resend when reconnected;
Data is uploaded to our self-developed IoT platform via 4G / LoRa;
The platform automatically analyzes against water-level and rainfall thresholds and triggers multi-level warnings;
Roadside warning stations replay the alert in the local language with sound and light, and push it to responsible officers via SMS, email or app.
Sensor → RTU → 4G / LoRa → Platform → Alarm

Typical Configuration

Water-level gauge: measures river water level in real time

Rain gauge: monitors rainfall

Data collector / RTU: gathers data and sends to cloud

Solar panel: powers the station, no grid needed

Warning siren: sound and light alarm in danger

Mounting kit: secures all equipment

Extensible components: flow meter (rivers / channels), camera (live site view), video equipment (urban waterlogging).

Typical Configuration of Flood Monitoring & Early Warning

Core Advantages

Plug-and-play

Pre-configured at the factory, no on-site commissioning; local workers can maintain it.

Ultra-low power

Average <5 W, runs on a 60 W solar panel; mains + solar dual supply, monitoring continues through power cuts.

Multi-network

4G + LoRa + Starlink full coverage; LoRa self-organizing network where no public network exists.

Open API

MQTT / HTTP protocols connect to your own platform — no data silos.

Non-contact radar sensing

Contact-free, resists silt and floating debris, millimeter accuracy, IP67 all-weather protection.

Local-language multi-level warning

Built-in voice for flash flood / landslide / debris flow, multi-level risk broadcast, platform remote on/off to prevent manual shutdown.

Remote management

Remote dispatch, one-touch reach, remote upgrade and remote diagnostics.
