For System M. Presence detector for indoor use with creep-under protection. The sensor module detects moving heat sources (e.g. people) in an adjustable detection area and starts a staircase lighting time. The sensor module has a light sensor with an adjustable brightness threshold so that the lighting is only switched on below a certain brightness threshold. The presence function enables the sensor module to switch the lighting off even if a person is present if there is sufficient natural light.
