The Sentry project uses an array of passive IR sensors placed in various rooms of a senior citizen residence to track motion about the facility. The system also uses motion sensors attached to chairs and beds to help determine if a resident is occupying the chair or bed. The systems are connected over an RF link to a processor with an attached WIZ550io to unobtrusively monitor the residents’ activity and decide if normal activity is present. Should the processing decide that the movement patterns are outside of normal behavior, an alert is sent to a remote family member or caregiver.
