System Components
-
Zigbee Gateway: Unifies all smart sensors, connecting them to the cloud and the APP platform.
-
Door Contact Sensor: Monitors entry/exit and frequency of movement at home.
-
Human Presence / PIR Motion Sensor: Detects indoor activity and occupancy to identify when someone is active.
-
Water Leak Detector: Provides early warning for water leaks in bathrooms and kitchens.
-
Smoke Detector: Instantly detects fire and smoke to ensure life safety.
-
Air Quality Sensor: Monitors harmful gases, temperature, and humidity for early warning.
-
APP Backend Management Interface: Centrally displays device status, activity logs, and abnormal alerts.
Principles and Automation Functions
-
Whole-house Activity Detection and Risk Identification
-
Door contact, human presence, and PIR sensors continuously record activity. Abnormalities in water, smoke, and air quality are reported automatically and instantly.
-
Set "inactivity time limits" and "abnormality thresholds" for each sensor; for example, if the door contact shows no activity for over 6 hours, or if there is no detection by PIR/human presence sensors, the system automatically flags an abnormality.
-
-
Instant Multi-Channel Alerts
-
APP sends push notifications to administrators/family members.
-
SMS and phone calls automatically notify registered family members, social workers, or institutional staff to ensure incidents are known immediately.
-
-
Centralized Management Operations
-
The backend interface displays sensor data, alert history, and the real-time status of the whole house, supporting multi-unit and tiered management.
-
Alert workflows can be configured uniformly, automatically notifying the appropriate personnel based on specific situations.
-
Practical Application Scenarios
-
Homes of elderly living alone or individuals with disabilities: Comprehensive prevention of accidents such as falls, fainting, leaving doors ajar, water leaks, and fires.
-
Elderly Homes / Public Housing / Community Care Projects: Mass deployment for institutions with remote, centralized monitoring to improve management efficiency.
-
Personal/Family Care: Instant protection and immediate notification of abnormalities, providing peace of mind even from a distance.
FAQ
How does the system know if an elderly person might have had an accident?
The system sets "inactivity time limits" for door contacts and PIR human presence sensors. For example, if a door has not been opened or closed for over 6 hours, or if there has been no activity detected by the PIR sensor, it is automatically deemed an abnormality. Water leaks, smoke, and air quality abnormalities are also reported instantly.
How are family members notified when an abnormality is detected?
The system supports instant multi-channel alerts: the APP sends push notifications directly to administrators or family members, and SMS or automated phone calls are made to registered family members, social workers, or staff to ensure they are informed immediately.
Is this system suitable for mass installation in institutions or residential buildings?
Yes. The backend management interface displays the status of all devices, activity logs, and alerts, supporting multi-unit and tiered management, making it ideal for mass deployment and centralized remote monitoring in elderly homes, public housing, or community care projects.
What equipment is required to build this monitoring system?
The core is a Zigbee Gateway used to unify all sensors. By adding door contact sensors, human presence/PIR sensors, water leak detectors, smoke detectors, and air quality sensors, a complete whole-house monitoring system can be established.
