Air Quality Monitoring
Creating healthier, more productive learning environments through real-time environmental monitoring.
Why Air Quality Matters in Schools
Indoor air quality is increasingly recognised as a key factor affecting student health, behaviour, and academic performance. Many UK classrooms suffer from poor ventilation, with CO2 levels regularly exceeding recommended thresholds — leading to drowsiness and reduced concentration.
EnviroSentry provides continuous, real-time monitoring of the key indicators that affect learning: CO2, PM2.5 particulates, volatile organic compounds (VOCs), nitrogen oxides (NOx), temperature and humidity.
Key Air Quality Indicators
CO2 (Carbon Dioxide)
Levels above 1,000 ppm impair concentration. EnviroSentry alerts staff when CO2 rises, prompting ventilation action before learning is affected.
PM2.5 (Particulate Matter)
Fine particulate matter can aggravate asthma and respiratory conditions. Laser particle analysis provides precise, real-time PM2.5 readings.
VOCs & NOx
Volatile organic compounds from cleaning products, furniture and building materials are tracked alongside nitrogen oxides from external traffic pollution.
Temperature & Humidity
Maintaining comfortable temperature and humidity levels directly supports concentration and wellbeing throughout the school day.
Actionable Data, Not Just Numbers
EnviroSentry doesn't just collect data — it helps you act on it. The local dashboard provides an intuitive overview of air quality across every monitored room, with colour-coded status indicators and historical trend charts.
When readings breach your configured thresholds, the system sends immediate alerts via the dashboard, SMS or email. Staff can take action within minutes — whether that's opening windows, adjusting ventilation, or relocating a class.
Historical data helps identify patterns over time, supporting evidence-based decisions about ventilation improvements and building maintenance.
What the Research Says
Classrooms with poor ventilation regularly exceeded CO2 levels of 1,500 ppm — well above the recommended 1,000 ppm threshold.
