The challenge

Schools and universities are often located near busy roads, yet rely on little to no continuous air quality monitoring — indoors or out. Poor ventilation, high occupancy, and proximity to traffic mean that classrooms can accumulate CO₂, PM2.5, and VOCs well above healthy thresholds, often without staff or students being aware. The result is measurable harm to attendance, concentration, and wellbeing.

The Persium approach

Persium deploys indoor and outdoor sensors across educational buildings and campuses — continuously monitoring the pollutants and environmental conditions that most directly affect learning environments. Data feeds into an intuitive dashboard, giving facilities teams, health & safety leads, and academic researchers real-time visibility into how air quality varies by room, building, and time of day. Configurable alerts notify staff when conditions drift beyond safe thresholds.

What schools & universities use it for

Classroom CO₂ monitoring:

Track carbon dioxide levels in real time to identify when ventilation is insufficient and cognitive performance is at risk.

PM2.5 & VOC exposure:

Measure fine particulates and volatile compounds from traffic, cleaning products, and occupancy to understand indoor exposure.

Attendance & wellbeing evidence:

Build a continuous data record linking air quality to absence patterns, supporting investment in ventilation improvements.

Campus outdoor monitoring:

Track pollution from surrounding roads and identify the highest-exposure routes, entrances, and outdoor spaces across the site.

Academic research support:

The Persium Indoor Pill is purpose-built for institutional research, providing high-precision, fully customisable monitoring for exposure studies and health impact analysis.
