Real-time, street-level air quality intelligence for local authorities and urban planners.



The Challenge

Most cities still rely on a handful of fixed monitoring stations and periodic reports. That leaves entire neighbourhoods, schools, and transport corridors effectively invisible.


The Persium Approach

Persium deploys dense sensor networks across key urban locations — capturing real-time, street-level data that reflects how people actually experience pollution. That data feeds into interactive dashboards, MapView heatmaps, and 3D digital twin environments, giving cities the visibility they need to act with confidence.


What cities use it for


Plan smarter:

Identify pollution hotspots, model new infrastructure, and test interventions before committing.


Protect communities:

Target resources where exposure is highest, from school streets to residential zones.


Report with evidence:

Meet regulatory requirements and communicate progress publicly with verifiable, continuous data.

Hyperlocal data for smarter planning:

deploy sensor networks across your city and collect street-level air quality data where it matters most.


Model before you build:

use digital twinning to forecast how new roads, green spaces, or traffic changes will affect pollution levels before implementation.


Design for cleaner streets:

pinpoint hotspots and plan spaces that encourage walking, cycling, and low-emission transport.
