Now in early access

One sensing platform,
built for anything you need to monitor.

A self-healing network of mutualized LTE gateways and low-cost sensors, scaling to virtually any size. Redundant and self-deploying, running for years without a battery change or a maintenance visit — even where there's no power outlet and no WiFi.

The problem

Deploying sensors at scale shouldn't be this hard

Most IoT monitoring solutions force a trade-off: cellular sensors that are expensive and power-hungry, or WiFi sensors that need power outlets and dense coverage. Neither scales to dozens or hundreds of measurement points.

Cost per sensor

Cellular radios and large batteries make individual sensors too expensive to deploy redundantly.

Power & wiring

Running power to every measurement point is often impossible in the field.

Connectivity gaps

WiFi doesn't reach outbuildings, remote sites, or spread-out equipment.

Fragile networks

A single point of failure — one gateway going down — takes the whole network offline.

One sensor, four senses

Temperature, humidity, vibration, and sound — out of the box

Temperature

Track thermal conditions on equipment, environments, or stored goods in real time.

Humidity

Detect moisture buildup before it becomes damage — indoors or outdoors.

Vibration

Catch abnormal movement, impacts, or mechanical wear as it happens.

Sound

Pick up acoustic signatures — from machinery noise to unusual activity.

How it works

From unboxing to live data in minutes

01

Drop the sensors

Battery-powered sensor nodes pair over Bluetooth — no wiring, no configuration.

02

Bridge relays over LTE

One shared LTE bridge collects data from every sensor in range and sends it to the cloud.

03

Network self-organizes

Sensors and bridges synchronize wake-up cycles and heal around failures automatically.

04

Configure rules & alerts

Every reading flows into a central platform. Set thresholds for your use case and get notified the moment something needs attention.

Innovation

Engineered for scale, battery life, and resilience

Generic Bluetooth sensor

Low-cost, low-energy compared to cellular, with multiple sensing capabilities in one node.

Mutualized LTE bridge

One bridge serves many sensors, with time synchronization that lets them wake up together and sleep the rest of the time.

Auto-healing network

Deploy multiple bridges: if one goes down, sensors automatically find another bridge to relay through.

Configurable & adaptive

Tune network behavior to your use case from a real-time web dashboard — and let it adapt automatically as conditions change.

Over-the-air updates

Ship improvements to sensors and bridges remotely, without a single field visit.

Mass-producible sensors

Low unit cost makes large-scale, redundant deployments affordable.

Fully battery-operated

No power outlet, no WiFi network required — sensors and bridges run independently for years without a battery change or a maintenance visit.

Zero-configuration setup

Drop the sensors and the bridge — the network discovers itself and starts reporting.

Two-way platform: collect data, send commands

Every reading reaches one central platform, and commands flow back to the field just as easily. Configurable rules turn signals into alerts today — the same dataset is what makes AI-driven analysis possible next.

Verticals

Build your product on KerSignal

We provide the sensing network — gateways, sensors, data platform. You build and brand the product for your market. Meliflo, our own build, shows what's possible.

Industrial & Agriculture

Predictive Maintenance Lite

For industrial SMEs & mechanized agriculture

Give industrial SMEs vibration, temperature and sound monitoring on isolated machines — no cabling, no per-machine gateway. Help them catch a failing motor or compressor before it costs a shift.

  • Ventilation motors, pumps & conveyors
  • Commercial refrigeration & cold rooms
  • Compressors & boiler rooms
  • Elevators, silos & small production lines
Heritage & Remote Sites

Heritage & Remote Buildings

For churches, museums, archives & vacant sites

Offer discreet, battery-only sensors for places that can't be rewired — humidity and temperature for conservation, vibration and sound for early warning. Installed in minutes, no drilling, no WiFi.

  • Rural churches, chapels & crypts
  • Municipal archives & small museum reserves
  • Vacant buildings, second homes & remote sites
  • Historic monuments & private estates
Live today

Smart Apiary

For professional beekeepers, co-ops & researchers

Our own build, live in the field. Meliflo runs on KerSignal, serving professional beekeepers, cooperatives, research institutes, and agricultural insurers.

  • Hive temperature, humidity, vibration & sound
  • Swarming and colony-stress detection
  • Theft alerts for remote apiaries
  • Fleet monitoring for professional operations

FAQ

Frequently asked questions

What can the sensors measure?
Every sensor node reports temperature, humidity, vibration, and sound. The same hardware adapts to different use cases through configuration, not custom builds.
How long does the battery last?
Because sensors and bridges synchronize their wake-up cycles, nodes typically run for years on a single battery, depending on reporting frequency.
What happens if a bridge fails?
With more than one bridge deployed, sensors automatically detect the outage and reconnect through another bridge in range — no manual intervention needed.
Do I need WiFi or a power outlet?
No. Sensors run on Bluetooth and battery power; bridges connect over LTE and can also run on battery, so the whole network can be deployed anywhere with cellular coverage.
Can I use this for a use case that isn't listed?
Yes — the platform is generic by design. We focus on three verticals today (predictive maintenance, heritage & remote buildings, and Smart Apiary); new ones are added as they're needed.
How is KerSignal different from Meliflo?
KerSignal is the underlying sensing platform. Meliflo is one application of it, purpose-built for beekeeping. KerSignal is for any business that needs the same technology configured for a different need.
