“The Stick” The Stick, a FLOOD-Mesh solar sensor node mounted on a pole
Off-grid flood intelligence

Real-time flood awareness, even when the grid is down.

A low-cost network of solar-powered sensors that measures flood levels and road conditions across your area, relaying data over long-range LoRa radio to live maps and alerts. No existing infrastructure required.

01What is it?

A city-wide fabric of low-cost sensors.

Each node, comprised of a radio, solar and configurable sensor suite, mounts to existing poles or infrastructure and reports road and water conditions continuously. Deploy one, or a thousand.

Always reporting

Nodes sample conditions around the clock and stream readings continuously, no site visits, no guessing.

Deploy anywhere

Strap a node to a lamp post, sign or a provided pole. There's nothing to trench, wire or connect. The communication network self assembles.

02How it works

From a sensor on a pole to a live situation map.

Nodes use LoRa for ultra-low-power, long-range links and intelligently relay readings through the network to a gateway. A central server turns the stream into live maps and predictive road-closure alerts. If a node fails, the mesh simply re-routes around it.

  1. 1

    Sense

    A node measures water level and road conditions where it stands.

  2. 2

    Relay

    Readings hop node-to-node over long-range LoRa radio. No cellular, no mains.

  3. 3

    Gateway

    A gateway collects the mesh traffic and forwards it on to the server.

  4. 4

    Map & alert

    The server publishes live maps & provides real time insights across the deployment.

03Why it matters

Resilient by nature, built to scale, open by design.

Who benefits

Residents, first responders and city planners get timely, ground-truth visibility of road and water conditions, helping the whole community make safer decisions and accelerating recovery after severe weather.

02

Resilient by nature

The mesh keeps communication flowing during power and cellular outages, adding an extra layer of emergency communication when it's needed most.

03

Built to scale

At roughly one-tenth the cost of a traditional river station, FLOOD-Mesh is designed for mass deployment across an area.

04

Open & flexible

Data is stored in non-proprietary, open formats that integrate with a wide range of software, so you can implement it however your team needs.

04FAQ

Common questions.

Q.Does it need internet or mains power to work?
No. Every node runs on solar and battery and communicates over its own long range LoRa mesh, so the network keeps working off grid with no new infrastructure to install.
Q.What happens if a node fails or goes offline?
The mesh re-routes automatically. Neighbouring nodes find a new path to the gateway, so a single failure doesn't take the network down.
Q.How does the cost compare to traditional monitoring?
A FLOOD-Mesh node costs roughly one tenth of a traditional river station. That is what makes mass, area wide deployment practical rather than a handful of fixed sites.
Q.Can we use the data in our own systems?
Yes. Data is collected and stored in non proprietary, open formats, so it integrates with a wide range of software and you can implement it however you need.
Q.Does it still work during a storm or outage?
That's the point. The mesh keeps communicating through power and cellular outages, and because data flows both ways it can double as an extra emergency communication channel.
