Abstract:
A method for controlling a light, comprising: providing a first sensor device (11) comprising a first transmitter and a first occupancy sensor;providing a lighting controller (1) comprising a receiver and a second sensor; and transmitting an occupancy signal from the first transmitter to the receiver. The occupancy signal comprises a repeated cycle of transmission phases and silent phases, such that during a transmission phase the transmitter transmits and during a silent phase the transmitter does not transmit. The method further comprises activating the light when the second sensor is triggered; and deactivating the light after a period of time, the length of the period being determined at least in part by the occupancy signal transmitted by the first transmitter.
