MICROWAVE SENSOR DEVICE, AND SENSING METHODS, AND LIGHTING SYSTEM USING THE SENSOR DEVICE

WIPO Patent Application WO/2020/035314

A8

A microwave sensor device is for detecting activity and for sending and/or receiving a communications signal to/from a second microwave sensor device. A microwave transceiver is used for transmitting a microwave transmit signal and for receiving a microwave receive signal. For motion detection, the microwave receive signal is a reflected version of the microwave transmit signal and the signals are processed to identify first signal characteristics. For communication, the microwave transmit signal is a communications signal for detection at another sensor device. The transmit and microwave receive signals are processed to identify second characteristics. This sensor device detects motion and also transmits and/or receives a communications signal using the same transceiver. In particular, the communications signal is designed to be detected by a remote sensor device in the same way as for motion detection.
