Document Type and Number:
WIPO Patent Application WO/2023/162723
Kind Code:
A1
Abstract:
This monitoring device comprises a first transmission/reception unit for transmitting first radio waves in a first range and receiving reflected waves of the first radio waves, a first sensing processing unit for sensing the presence/absence of an object in the first range and acquiring first information relating to the object sensed in the first range, a second transmission/reception unit for transmitting second radio waves in a second range that is larger than the first range and receiving reflected waves of the second radio waves, and a second sensing processing unit for sensing the presence/absence of an object in the second range and acquiring second information relating to the object sensed in the second range, the first information including identification information with which it is possible to determine whether the object is a living thing.
