Environmental intelligence at street level

Real-time data from mobile sensor networks. Real measurements, not estimates.

The solution

The problem

Sparse static stations mean low-resolution maps and estimated data, not real measurements. Pollution stays invisible where it matters. No real street-level data.

Our approach

Sensors on fleet vehicles, 24/7 collection along real routes, processing in the cloud, delivery via APIs. The solution is one path: from the fleet to the cloud to you.

The Sparrow Nodes Fleet is that solution: fleet, cloud, you.

Nodes Fleet

Nodes on vehicles capture street-level data and send it to the cloud.

Sparrow Cloud

Processing, storage, and calibration in the cloud.

Data APIs

Validated data available via API for your apps and products.

Meet Sparrow Fleet

A network of vehicles fitted with Sparrow Nodes. They run normal routes while scanning streets and collecting high-resolution environmental data. Each vehicle is a mobile sensing unit for real-time, street-level coverage.

How it works

1Partner with fleet operators.
2Equip vehicles with Sparrow Nodes. Plug-and-play.
3Vehicles run normal routes. No change to operations.
4Data collected every few meters, uploaded in real time.
5Process and deliver via API.

Why fleet-based monitoring?

Full-city coverage

Coverage is what makes the data useful. Fleet vehicles cover entire cities daily, more streets scanned, more often, so your apps get street-level data where it matters.

High spatial resolution

Street-level data instead of a handful of fixed stations. Denser sampling means your maps, routing, and analytics reflect real conditions block by block. Better inputs for your models and user-facing features.

Scalable infrastructure

New city: partner with a fleet, install nodes, start scanning. No permits, grid planning, or large maintenance teams. Scale your data footprint with your business and bring street-level intelligence to new markets fast.

Cost efficient

Lower cost than building stationary sensor networks. Fleet-based collection spreads cost across existing operations. Premium environmental data at a fraction of traditional deployment cost.

Sparrow Node

What it does

The node is the core of our network. On the vehicle it captures environmental data along every route: air quality, road surface, noise. One device, many signals, continuously.

What it collects

Air: particulates, gases, climate. Road: surface quality and bumps. Noise: exposure and events. Plus GPS. Calibrated sensors, street-level resolution.

How easy it is

Plug-and-play. No structural change to the vehicle. Rugged, built for fleet use. Install and go.

What you get

Real measurements, not estimates. High resolution, frequent, mobile. Data ready for your maps, apps, and APIs.
