Abstract
The invention relates to a method () for monitoring the density and the movement of humans using a grid () of a plurality of luminaires (-), each of the luminaires (-) comprising an acoustic sensor (), a motion sensor (), preferably a Doppler sensor, a controller () supplied with output signals of said sensors (), and a wireless interface () for a communication between the controller () and a gateway () for forwarding sensor information signals () to a central database (), wherein, based on the information in the database (), the density and/or the movement of humans in an area covered by the grid () is estimated by generating a time series of sensor values, such as sound pressure, motion speed and/or motion intensity, of each luminaire (-).
