## What is LightFi Air?

This app displays live indoor Carbon Dioxide (CO₂) levels and other sensor data measured by LightFi sensors. Multiple sensors can be monitored simultaneously. You can give each sensor a unique name. When it scans the app sorts each sensor by approximate distance nearest first.

It is important to monitor your indoor CO₂ levels for your health, well-being, and productivity. Research from Harvard University shows that continuous exposure to high CO₂ levels can diminish productivity, cause headaches, and increase the risk of viral transmission. When indoor CO₂ levels are high please increase fresh air flow, by opening a window for example.
