A quick and simple tool for estimating real-time natural ventilation rates in public indoor spaces and comparing them to building regulations and recommendations.

Use a blue-tooth linked COZIR CO2 sensor to determine instantaneous indoor ventilation rates.
The app will also define high, medium and low airborne transmission risk levels and recommend occupancy limits based on WHO recommendations.

Important:
CO2 sensor must be in streaming mode.
Pairing to blue-tooth device must be completed prior to launching app.
Bluetooth device must be named BTCO2 for recognition by app.
App will run in manual mode until correct blue-tooth device is found.
In-App calibration of sensor happens automatically. Just confirm the known outdoor reading from device and click accept.
Give sensor a few minutes to warm up before proceeding with measurements.
