Professional & Technical Excellence
Unlike traditional PIR sensors that only detect motion, this ceiling-mounted smart sensor utilizes advanced 24GHz mmWave radar technology. It provides real-time detection of human presence, including stationary individuals and sleeping states. The integration of a dedicated illuminance (Lux) sensor allows for intelligent, context-aware lighting control, ensuring lights only activate when necessary and stay on while the room is occupied.
Authoritative Specifications & Installation
Designed for flush ceiling mounting (suggested at a height of approximately 2.75 meters), the sensor offers a precise 90° detection angle. The detection zones dynamically adapt to user activity:
Motion Detection: Up to 6m x 8m
Stationary/Geostationary Motion: Up to 4m x 6m
Sleep Detection: Up to 3.6m x 2.2m
(Note: This device requires a Zigbee 3.0 compatible gateway to function and does not operate standalone).
Trustworthy Safety & Automation
This device prioritizes personal safety, particularly for elderly individuals. By utilizing its fall detection algorithm, if a fall is detected in high-risk areas like bathrooms or restrooms, an immediate alarm notification is pushed to the user's app, allowing family members or caregivers to respond quickly. Furthermore, it enables comprehensive smart home automation, such as automatically turning on lights and air conditioning when returning home at night, and turning off appliances when leaving—all controllable remotely via the app and voice commands (powered by AC 220V).
FAQ
Q1: Does this sensor require a gateway to function?
A1: Yes, this device operates on the Zigbee 3.0 protocol. As explicitly noted in the product specifications, it cannot work standalone. It must be connected to a compatible Zigbee gateway, which then connects to your Wi-Fi router to enable app control, remote monitoring, and smart automation.
Q2: How is mmWave radar technology better than standard PIR sensors?
A2: Standard PIR sensors rely on infrared heat changes and will turn lights off if you are sitting still. The 24GHz mmWave radar technology used in this sensor detects micro-movements, allowing it to accurately detect human presence even when you are stationary, sleeping, or reading, preventing sudden blackouts.
Q3: How does the fall detection feature work?
A3: The sensor features a dedicated fall detection function. When a fall is detected (such as an elderly person slipping in a bathroom), an alarm status is immediately triggered and pushed to the connected app. This ensures caregivers or family members are alerted in real-time for prompt rescue.
Q4: What are the recommended installation height and detection ranges?
A4: For optimal performance, it is recommended to install the sensor on the ceiling at a height of about 2.75 meters. It provides a 90° detection angle. The detection range is approximately 6m x 8m for active motion, 4m x 6m for stationary motion, and 3.6m x 2.2m for sleep detection, allowing flexible placement based on room structure.
