Wenzhi WZ-M100 Human Presence Motion Sensor – Ceiling-Mounted WiFi Presence Detection
Create a more responsive smart home with the Wenzhi WZ-M100 Human Presence Motion Sensor, a radar-based device described for detecting human presence and movement inside a room.
Unlike basic motion detection, human presence sensing can respond to smaller movements, helping compatible automation systems recognize when a person remains in a space.
This WiFi Human Presence Sensor is intended for ceiling installation and can support compatible smart lighting automation through Tuya Smart or Smart Life.
When correctly configured, the sensor can form part of presence-based scenes, automatic lighting routines and other compatible smart home functions.
Advanced Human Presence Detection
The sensor is designed to help detect whether a person is present within its monitored area.
Radar-based detection can recognize certain subtle movements that may not trigger a conventional motion-only detector.
Actual performance depends on sensitivity, installation position, room layout and the specific hardware version.
Millimeter-Wave Radar Technology
The WZ-M100 product family is described as using radar sensing technology to monitor movement and presence.
The available descriptions mention 5.8GHz and 24GHz variants within the broader product range.
The exact operating frequency must be confirmed for the supplied WiFi model.
Smart WiFi Connectivity
The WiFi version can connect to compatible smart home functions without using a Zigbee connection.
Supported features may be configured through Tuya Smart or Smart Life, depending on the model.
A suitable wireless network and proper device pairing are required.
Ceiling-Mounted Design
This Ceiling Mounted Presence Sensor is designed for installation at a suitable position above the monitored area.
Ceiling installation can provide a convenient view of room occupancy in spaces such as living rooms, offices and internal corridors.
Installation height, coverage and orientation must follow the actual product manual.
Key Features of the Smart Presence Sensor
- Human Presence Detection: Monitors occupancy-related movement within the configured detection area.
- Radar-Based Sensing: Supports the detection of selected subtle movements.
- WiFi Connectivity: Designed for compatible WiFi smart home setups.
- Ceiling Installation: Suitable for overhead mounting according to the supplied model.
- Tuya Integration: Supports compatible smart scenes and automation settings.
- Adjustable Detection: Sensitivity and distance settings are described for supported variants.
- Lighting Automation: Can trigger compatible presence-based lighting scenes.
- Ambient Light Functions: Available on variants that include illuminance sensing.
Human Presence Detection vs. Motion Detection
A conventional motion sensor often responds to obvious movement such as walking across a room.
A Smart Human Presence Detector uses a different detection approach to identify occupancy-related movement, including smaller changes in some situations.
This can help compatible lighting systems stay active while a person remains inside a room.
Sensitivity and correct placement are important to reduce unwanted triggers and improve detection.
Automatic Smart Lighting Control
The sensor can be used in compatible automation routines based on room presence.
For example, a smart scene may switch on lighting when presence is detected and switch it off after the room has remained unoccupied for a configured period.
These automations can improve everyday convenience and help avoid unnecessary lighting use.
The connected lighting products must support the selected automation platform and scene settings.
Tuya Smart and Smart Life Automation
The Tuya WiFi Presence Sensor can be integrated into compatible app-based smart home routines.
Depending on device support, users may be able to create automation rules, adjust selected parameters and link sensor states to supported smart devices.
The available controls should be checked after pairing the sensor with the correct application.
Ambient Light Detection
The original product information mentions ambient light monitoring for some versions of the sensor family.
A stated range of 0–2000 lux appears in the existing specifications.
Where supported, this information may help build automation rules based on both room occupancy and light level.
Illuminance detection must be verified for the supplied ceiling-mounted WiFi variant.
Adjustable Detection Sensitivity and Range
The product family is described as offering adjustable sensing parameters on supported versions.
The existing description mentions sensitivity levels from 1 to 9, alongside adjustable detection distances.
Some variants list a range of up to 9.5 meters.
These figures should not be assumed to apply to every version; confirm the exact limits using the device specifications.
Ceiling Installation and Electrical Requirements
The existing information lists a ceiling-mounted variant with an 80–240V AC power requirement.
Other versions in the same product family are described as using 5V USB, particularly wall-mounted configurations.
Do not use power requirements from a different model.
Check the rating label and supplier instructions before installation, and use a qualified technician for mains electrical wiring.
