Installation

DETECT IAQ should ideally be mounted between 1.5 
to 1.8 m above the floor on the surface of a wall using 
screws, see figure 1.
The installation position needs to be selected with care to 
eliminate fault factors that can affect the measurement.
The sensor should not be exposed to sunlight, draughts or 
temperature differences caused by external walls.
