  • Patent number: 11819315
    Abstract: A human condition detection device comprises a depth image-taking module for taking a depth image of a target area. A millimeter-wave radar module detects breaths or heartbeats in the target area to provide a signal. A thermal image-taking module takes a thermal image of the target area. A processor module determines whether a person is in the target area based on the depth image. The processor module determines whether there is any breath or heartbeat based on the signal if a person is in the target area. The processor module determines whether there is any abnormal vital sign of the person in the target area based on the signal and the thermal image if there is a breath or heartbeat in the target area. The processor module actuates the warning module to provide a warning if there is an abnormal vital sign of the person in the target area.
