luminosity and Rader sensor
It adopts dual-mode detection technology (millimeter wave radar + PIR (Passive Infrared)), breaking the limitations of traditional sensors: it can not only accurately identify moving human bodies but also capture stationary human bodies (e.g., standing, sitting quietly) and micro-movements (e.g., breathing, blinking, subtle reactions after a fall) without detection blind spots. Equipped with a 90° detection angle, it can cover common indoor spaces such as living rooms and bedrooms, avoiding missed detections caused by insufficient detection range. Meanwhile, it supports accurate judgment of "occupied/unoccupied" status, significantly reducing the probability of false triggers.
It supports dual wireless communication modes (WiFi and Zigbee) and must be operated with the "Tuya Smart" or "Smart Life" APP:
WiFi Version: No additional hub is required; it can connect directly to a home WiFi router for out-of-the-box use. Suitable for single-room smart renovations or rental scenarios.
Zigbee Version: Requires a Tuya Zigbee hub (not included in the package). The hub serves as the core of the whole-house smart system, connecting other Tuya Zigbee devices (e.g., lights, air conditioners, curtains) to achieve more stable multi-device linkage, meeting the needs of whole-house smart setups.
Power Adaptability: Supports AC 110V-240V wide-voltage input, no additional voltage converter needed. It can be directly adapted to most household and commercial power supply environments worldwide, with strong compatibility.
Detection Distance: Supports custom minimum/maximum detection distance within 0.1-9.5m (default effective distance 0.3-6m), allowing precise definition of the sensing area based on scenarios (e.g., small bedrooms, large living rooms).
Environmental Sensing: Integrates illuminance detection (0-2000Lux) to monitor ambient brightness in real time, providing data support for device linkage (e.g., "automatically turn on lights when illuminance is insufficient").
Working Parameters: Detection confirmation delay (Detec_Delay) and signal fading time (Fading_Time) are adjustable (default detection delay 0.0s, fading time 60.0s), adapting to the response speed requirements of different scenarios. The product is made of ABS material, white in color, impact-resistant, anti-aging, and has a long service life.
Flexible Installation: Offers two installation options (ceiling-mounted and wall-mounted)—ceiling-mounted installation requires a 53-58mm (2.09-2.28inch) hole, and the product dimensions are 61mm×39mm×46.5mm (2.4×1.54×1.83inch), suitable for most ceiling structures; wall-mounted installation dimensions are 58mm×58mm×11mm (2.28×2.28×0.43inch), which can be fixed without drilling, adapting to walls, cabinets, and other scenarios.
Packaging Configuration: Products are packed in retail packaging and then placed in cartons. A single package includes 1×human presence detector and 1×user manual, meeting basic installation and usage needs. Customization services are available (custom logos, packaging, graphics)—the minimum order quantity (MOQ) for logo customization is 100 pieces, and the MOQ for packaging and graphic customization is 1000 pieces, catering to branding needs.
It provides a 1-year product warranty to ensure stable performance during the service life. The product has passed compliance certifications such as RoHS and CE, meeting safety and environmental standards, and can be safely used in home, commercial, and other scenarios.
The combination of millimeter wave radar and PIR technology not only solves the defect that traditional PIR "cannot detect stationary human bodies" but also improves detection accuracy through the high-precision characteristics of radar (±10cm distance error). Meanwhile, it supports adjusting detection distance (0.1-9.5m), sensitivity, and delay time in the APP, which can be optimized according to scenarios—for example, reducing the detection range in bedrooms to avoid false triggers and expanding the range in living rooms to ensure full coverage, further reducing missed detections and false alarms.
The WiFi version requires no hub and can be used directly by connecting to a router, with a low entry barrier, suitable for "lightweight" needs such as renting or single-room smart upgrades; the Zigbee version achieves multi-device linkage through a hub, with stable signal transmission, and can build a whole-house smart system where "lights, air conditioners, and TVs respond collaboratively", balancing "convenience" and "scenario integrity" to meet the usage scenarios of different users.
One-stop smart management can be achieved through Tuya ecosystem APPs:
Real-Time Monitoring: Remotely check the "occupied/unoccupied" status and receive real-time alerts for human detection (e.g., push reminders when a human is detected during non-working hours).
Parameter Adjustment: Set parameters such as detection distance, sensitivity, and illuminance linkage thresholds directly in the APP without on-site operation.
Historical Records: Query past human detection and device linkage records to trace scenario usage patterns (e.g., checking "children's study duration" in home scenarios).
Linkage Configuration: Visually set linkage rules (e.g., "detect human → turn on study desk lamp", "5 minutes unoccupied → turn off living room air conditioner") without complex programming.
It supports in-depth linkage with smart devices in the Tuya ecosystem (lights, air conditioners, sockets, exhaust fans, etc.):
Convenient Scenarios: When returning home at night, the detector automatically turns on the entrance light and living room air conditioner after detecting a human, no manual operation required.
Energy-Saving Scenarios: After leaving home, it automatically turns off all non-essential appliances (e.g., TVs, desk lamps) to avoid energy waste caused by forgetting to turn off lights.
Eye Protection Scenarios: Combined with illuminance detection, when the illuminance in the study is below the threshold, it automatically turns on the desk lamp and adjusts it to an appropriate brightness to protect eyesight.
The wide-voltage design (AC 110V-240V) can adapt to most power supply environments worldwide, applicable to homes, hotels, and office buildings. The dual installation methods (ceiling-mounted/wall-mounted) require no complex wiring, and ordinary users can complete installation independently, adapting to different decoration styles and space structures, with strong practicality.
Entrance/Living Room: The WiFi version directly links to lights and air conditioners, realizing "automatically turn on lights and air conditioners when returning home, and turn off when leaving", enhancing daily convenience; in the living room scenario, it can automatically adjust devices such as TVs and humidifiers based on the "occupied/unoccupied" status to avoid energy waste.
Bedroom/Elderly Room: Using the micro-movement detection function of millimeter wave radar, it monitors the breathing, heartbeat of the elderly during sleep or their static state after a fall, and pushes alarm reminders via the APP in case of abnormalities; when getting up at night, it automatically turns on night lights to avoid safety hazards of fumbling for switches.
Study/Children's Room: Combined with illuminance detection and desk lamp linkage, when the ambient illuminance is below 200Lux (customizable threshold), it automatically turns on the desk lamp and adjusts brightness to protect children's eyesight during study or adults' eyesight during work. Meanwhile, it assists in managing study/work duration through detection records.
Hotel Guest Rooms: The Zigbee version is integrated with the hotel's whole-house smart system—when guests check in, it automatically turns on welcome lights and air conditioners; after check-out, it automatically cuts off power to non-essential devices to reduce hotel operating energy consumption. Meanwhile, it can assist in the efficient scheduling of cleaning staff through "unoccupied status" detection (e.g., notifying cleaners to tidy up the room after confirming guests have left).
Office Areas: In areas such as office corridors and meeting rooms, it automatically turns on lighting when a human is detected and turns it off when unoccupied to save office energy consumption; in meeting rooms, it can link with projectors and air conditioners to realize "automatically start devices when occupied and turn off after the meeting", improving work efficiency.
Kitchen: It automatically turns on kitchen lights and exhaust fans when a human is detected entering, and turns them off with a delay after leaving, avoiding the trouble of manually touching switches in an oily environment and reducing energy waste.
Bathroom: Combined with illuminance and human detection, it automatically turns on bathroom lights and turns off exhaust fans after no one is present, keeping the bathroom dry and reducing the risk of mold growth
