Radar and ZigBee Sensors for Senior Care Monitoring

Short answer: The OWON FDS315 uses a 60 GHz radar to detect falls, location of activity, out-of-bed events and breathing rate during sleep, and the OPS305 detects presence by radar even when a person is stationary. Both join a ZigBee gateway and can be combined with door, leak and multi-sensors.

Which sensors can be used?
