Improving classroom air quality and ventilation with IoT-driven acoustic and visual CO2 feedback system

In classrooms, air quality often depends on teachers opening windows—but what if smart sensors could help? Our study found that IoT CO₂ alerts cut CO₂ by ~20%, but raised new questions about comfort, energy use & air quality balance. 👉 Read more: h…

Can real-time data improve classroom air quality? 📊 This study shows a 19% drop in CO₂ with IoT alerts — but also trade-offs in thermal comfort & energy use. Smarter signalling = healthier schools. 🔗 Full study: https://t.co/HsXcG85V7e https://t.…
