Abstract

The invention relates to an occupancy sensor (1) for detecting occupancy comprising an ultrasound transmitting device (2), at least one microphone (M1-M4), a processor unit (3) adapted to receive data from said microphone and send and receive information to/from said ultrasound transmitting device (2), a memory (4) storing instructions to be performed by the processor unit (3), wherein said processor unit (3) is adapted to detect movements and presence of objects from data of reflected ultrasound measured by said at least one microphone (M1-M4), wherein the at least on microphone (M1-M4) is a broad band microphone used for receiving both ultrasound and audible sound, wherein said processor unit (3) is further adapted to use audible sound to enhance detection of living presence. The invention further relates to a method of determining occupancy using an occupancy sensor (1) for detecting occupancy comprising an ultrasound transmitting device (2), at least one broad band microphone (M1-M4), able to record both audible sound and ultrasound, a processor unit (3), a memory (4) storing instructions to be performed by the processor, said method comprising the steps of: sending an ultrasound pulse from said ultrasound transmitting device, receiving data from said microphone of the echo of said ultrasound pulse, making a first calculation using said processor unit of a probability of movements and/or presence of objects from data of the measured reflected ultrasound measured by said microphone, making a second calculation using said processor unit of a probability of movements and/or presence of objects from measured audible sound.
