How does Sentinel Cloud work?

We read satellite data (VIIRS, MODIS y GOES-19) and combine it with geospatial information and artificial intelligence to flag likely fire hotspots and send a geolocated alert. Our accuracy target is 98%: it is a goal, not yet a result measured in the field. Today the reading is satellite-based; we are adding sensors and drones step by step.

What if the AI gets it wrong and raises a false alarm?

It can happen, and it is the first question any fire brigade asks: a false alert costs time and resources. That is why the model cross-checks several sources before alerting, and that is the basis of our 98% accuracy target, which we must validate in pilots together with each client.

How much does it cost to implement Sentinel?

There is no upfront investment in equipment (CAPEX): the model points to a Sentinel Cloud subscription over the coverage you need. The price is defined according to the territory. We start with a limited pilot to validate results before a larger contract.

How long until it is operational in my territory?

Our goal for a pilot is to generate alerts within 4 to 8 weeks of the start (internal estimate, to be confirmed depending on the territory). The platform is cloud-based: there is no construction or infrastructure to install on your side, you only need to define the area to cover and have internet access.

Is the live data on the website from the Sentinel network?

No, and we want to be clear: the risk index and the hotspot map use public sources (Open-Meteo and NASA FIRMS) for illustration, to show the same kind of variables our system processes. A client's deployment data is not public and is not shown on the website.

Sentinel Cloud | Early wildfire detection

Sentinel reads the satellites and sends a WhatsApp alert with location and access to whoever has to act. For municipalities, fire brigades and producers across Patagonia. All from the cloud, nothing to install.

What Sentinel does

Early wildfire alerts, for municipalities, fire brigades and producers.

We detect
We read the fire hotspots that satellites (NASA FIRMS and GOES-19) see over the Patagonian Andes.
We verify
We cross-check the sources and rule out industrial heat before alerting anyone.
We alert
We send a WhatsApp alert with location and access. Target: 8 minutes from detection.

Everything runs in the cloud, no equipment to install. We are running an open pilot today: there are no published cases with measured results yet.

The problem

A fire is stopped by a crew or becomes a front.

Almost every big wildfire starts small: in the first minutes, a crew and a pump are enough.
In the mountains and the steppe there are almost never witnesses: the fire is noticed when the smoke column is already visible from far away.
If the brigade arrives early, it works on a small perimeter. Our goal is to alert it within 8 minutes.

What is at stake

Who we are

We are four engineers from Patagonia who want fires to be seen sooner.

We started Sentinel at university and we keep building it ourselves. We don't have pilots with measured results yet, so we show you who we are, what recognition the project has received and how we measure what we claim.
