What is SenseOS indoor air quality monitoring?

SenseOS indoor air quality monitoring uses wireless sensors to continuously measure CO₂, PM2.5, temperature, humidity and VOC. Readings stream to the web platform and mobile app, property teams are alerted automatically when limits are exceeded, and long-term reports can support IAQ certification applications. Most floors are installed within half a day, without cabling or shutting down air-conditioning.
