Wenzhi ZigBee Wifi MmWave Human Presence Motion Sensor

1. Pendahuluan

The Wenzhi ZigBee Wifi MmWave Human Presence Motion Sensor is a versatile smart device designed to accurately detect human presence, static states, micro-motions, and general movement within an area. It also features luminosity and distance detection capabilities, enabling advanced home automation scenarios through the Tuya Smart Life ecosystem. This manual provides detailed instructions for installation, setup, operation, and troubleshooting to ensure optimal performance of your sensor.

2. Spesifikasi

The WZ-M100 series offers both 5.8GHz and 24GHz radar options, available in wall-mount and ceiling-mount configurations. Refer to the table below for detailed specifications.

Note on Detection Distance: The detection distance refers to the maximum linear distance from the sensor to a target (moving, micro-moving, or breathing). It is not the maximum diameter or radius mapped to the ground. The sensor has a distance resolution of approximately 1m. For example, if set to 3m, triggering within ±1m of the 3m position is considered normal. The distance value is primarily for filtering through glass partitions, gypsum boards, and wooden partitions, not for strict area division in presence detection.

4. Instalasi

4.1 Prinsip Instalasi

• General Indoor Areas (Hallways, Changing Rooms, Kitchens): Install as centrally and firmly as possible.
• Bathrooms/Toilets: Install 0.4-0.6m in front of the top of the toilet/squatting position, away from doors, windows, and exhaust fans.
• Living Room/Dining Room/Conference Room: Position 0.5-1m in front of the sofa, directly above the table.
• Bedroom/Study: Directly above the bed, or within 0.6-1.5m behind/in front of the desk.
• Glass/Gypsum Board Partitions: Position the sensor as close to a solid wall as possible. If only glass/gypsum walls are present, install centrally and adjust detection range and sensitivity to prevent false detections outside the intended area.
• Sitting, Squatting, Standing Still Scenes: For ceiling-mounted sensors, position 0.4-0.8m in front of the head's top. Avoid direct overhead installation. Wall-mounted sensors are generally better for detecting sitting still.
• Dense Deployment: Maintain a linear spacing of at least 5m between sensors.

4.2 Instalasi Dinding

1. Ensure the installation location is 1.5 to 2 meters above the ground.
2. Power the sensor using a 5V 1A USB power supply.
3. Apply the provided double-sided adhesive to the back of the wall-mounted sensor.
4. Firmly attach the sensor to the desired wall position.

4.3 Ceiling-Mounted Installation

1. Create an opening in the ceiling with a diameter of 53-58mm (55mm recommended).
2. Connect the sensor to an 80-240VAC power supply.
3. Insert the sensor into the ceiling opening and secure it using the two end buckles.
4. It is recommended to complete network configuration before final installation in the ceiling.

5. Setup & App Operation

5.1 Instalasi Aplikasi

To control your sensor, download the "Tuya Smart" or "Smart Life" app from your device's app store. Alternatively, you can scan the QR code provided in the original PDF user manual for direct download. After installation, register and log in to your account.

5.2 Device Network Connection

For initial use, the sensor needs to be connected to your network. ZigBee versions require a ZigBee gateway (hub), while Wi-Fi versions connect directly to your Wi-Fi network.

1. Nyalakan: Upon first power-on or if not yet networked, the device will automatically enter pairing mode. The red indicator light will flash quickly. If pairing fails or the red light does not flash, re-power the device or press and hold the network button for more than 5 seconds to re-enter pairing mode.
2. Tambahkan Perangkat di Aplikasi: Open and log in to the Tuya Smart/Smart Life app. Tap the "+" symbol in the upper right corner and select "Add Device".
3. Discovery & Confirmation: The app will search for nearby devices. Once your sensor is discovered, tap "Add". After successful addition, the sensor's red indicator light will turn off.

5.3 ZigBee2mqtt Support

To integrate your ZigBee sensor with ZigBee2mqtt, ensure your ZigBee2mqtt installation is updated to the latest version. If issues persist, you may need to download the specific JS file and configure it according to the documentation available at: https://github.com/wzwenzhi/Wenzhi-ZigBee2mqtt

6. Petunjuk Pengoperasian

6.1 Detection Functions

The sensor provides various detection capabilities:

• Fretting Detection: Detects small movements like tilting the head, waving, raising a hand, flicking the body, playing with a mobile phone, or turning a book page.
• Deteksi Kehadiran: Detects the human body in a stationary state (e.g., standing still, squatting still, sitting still).
• Deteksi gerakan: Detects larger movements such as walking, jogging, fast running, circling, or jumping.
• Pengukuran Jarak: Accurately filters targets outside a specified area based on their distance from the sensor.

6.2 Luminance Detection

The sensor includes an illuminance monitor (0-2000 LUX) that can be used in the Tuya Smart app for smart scene linkages. For example, you can configure your house lights to turn ON/OFF automatically based on changes in ambient brightness.

6.3 Adjustable Parameters

A variety of parameters can be adjusted via the Tuya Smart Life app to customize the sensor's behavior:

• Kepekaan: Adjustable from 1-9 (default 7) to fine-tune detection.
• Jangkauan Deteksi: Set minimum (e.g., 0.00m) and maximum (e.g., 9.5m) detection distances.
• Unmanned Delay (Hold Time): Configurable from 5-1500 seconds (default 15s) to determine how long the sensor waits after no presence is detected before changing state.
• Presence Confirmation Delay: Adjustable from 0-100 seconds (default 0.1s) to confirm presence.
• Interval Laporan: Sets the frequency of data reporting (1-3600s, default 5s). Note that detection status changes are reported immediately, regardless of this setting.

7. Penyelesaian masalah

Here are common interference sources and recommended solutions:

• Kipas: Change the position of the fan or sensor. Ensure the fan is outside the presence detection area.
• AC: The air swing and louver vibration of the AC should be outside the sensor's presence detection area.
• Rolling Shutter with Aluminum Alloy Lower Rail: Set an appropriate detection range to filter out such interference.
• Kipas Buang: Avoid exhaust fans or vibrating surfaces within the sensor's detection range. Secure the exhaust fan to prevent ceiling vibration.
• Strong 5.8GHz WiFi Signal Interference:
  • For WiFi routers in the front area of the sensor, maintain a distance of at least 3m.
  • For routers in other directions, maintain a distance of at least 1.5m.
  • When using a top-mounted Access Point (AP), maintain a distance of at least 1.5m from the sensor.
• Air Flow (Wind): Adjust the sensor's sensitivity setting.
• Hewan: Adjust sensitivity and the nearest detection distance to minimize false triggers from pets.
• Low-Frequency Vibration: Avoid direct exposure of radar signals to sound systems or other vibration sources. Set a relatively low sensitivity to prevent false triggering and use a longer presence confirmation delay time.
• Restricted Usage Scenarios: Avoid installing in elevators, metal-sealed toilets, or similar all-metal sealed spaces. Also avoid scenarios where the plane area of metal decorative materials outside the non-ceiling area exceeds 20%.

8. Kiat Pengguna

• ZigBee Sensor Lag: Some users report a communication delay (lag) of 5 to 10 seconds for battery-powered ZigBee presence sensors. While this sensor is mains-powered (80-240VAC or USB 5V), it's good practice to test its response time in your specific setup, especially for critical automation.
• ZigBee2mqtt Integration: If you're using ZigBee2mqtt, always ensure it's updated to the latest version for best compatibility and performance with your Wenzhi ZigBee sensor. Refer to the official Wenzhi GitHub for specific configuration files jika diperlukan.
