The HALO Smart Sensor measures relative humidity which plays an important role in the survival of virus’s in the air as well as how long they remain airborne.

The recommended Humidity level is 40-60% relevant to comfort but also infectious disease. If the humidity sensor detects humidity levels above 60% or below 40% it will trigger a Health Index event.

At 60% humidity or higher the moisture in the air allow virus’s live longer.

Below 40% humidity particular matter stay suspending in the air longer allowing it to travel a greater distance.
