Uživatelská příručka k senzoru pohybu osoby WENZHI MmWave

1. Úvod

The WENZHI MmWave Human Presence Motion Sensor is an advanced smart device designed for home automation, offering precise human presence, motion, fretting, luminance, and distance detection. It integrates with the Tuya Smart Life ecosystem and is available in WiFi, ZigBee, and Bluetooth connectivity options. This manual provides detailed instructions for installation, operation, and troubleshooting to ensure optimal performance of your sensor.

3. Nastavení

3.1 Možnosti montáže

The sensor is available in two mounting types:

• Držák na strop: Designed to be installed like a downlight.
• Montáž na stěnu: Can be attached to a wall or any desired surface.

3.2 Napájení zařízení

• Ceiling Mount Sensor: Requires 80-240VAC direct power connection.
• Wall Mount Sensor: Powered via USB 5V.

3.3 Connectivity and Pairing

For ZigBee and Bluetooth versions, a Tuya ZigBee/Bluetooth gateway (hub) is required to connect the sensor to your smart home system. The sensor integrates with the Tuya Smart APP for configuration and control.

4.1 Detection Functions

The sensor offers various detection capabilities:

• Fretting Detection: Detects subtle movements such as head tilting, waving, hand raising, body flicking, mobile phone use, or turning book pages.
• Detekce přítomnosti: Identifies the presence of a human body even in a stationary state.
• Detekce pohybu: Recognizes movements like walking, trotting, running, circling, or jumping.
• Měření vzdálenosti: Accurately filters targets outside a specified area.

4.2 Luminance Detection

The integrated illuminance monitor allows for smart scene linkage. For example, you can configure your house lights to turn ON/OFF automatically based on changes in ambient brightness. This feature enables intelligent home automation when linked with other smart devices in the Tuya Smart APP.

4.3 App Parameter Settings

The Tuya Smart APP allows you to customize various parameters for optimal performance:

• Citlivost: Adjustable from 1-9. Higher values increase sensitivity to object presence.
• Unmanned Delay Time: Sets the duration (0-1500s) after a person leaves before the system switches to an 'unmanned' state. Default is 90 seconds.
• Farthest Detection Distance: Configures the maximum detection range (0.00m to 9.5m). The detection angle is 110°, so a greater distance results in a larger detection area.
• Detection Latency: Adjustable from 0-10s to reduce false alarms from irrelevant movements.

4.4 Propojení scén

Automation can be triggered based on two conditions: the light-sensing value and the sensing state (someone present or no one present). For example, you can set up an automation: "If sensing state is 'someone', then turn on the living room light."

4.5 Installation Location and Area Considerations

The sensor uses microwave technology to detect micro-motion. While algorithms suppress interference from things like fluttering curtains, actual testing may be required for specific environments.

• Držák na strop: Easier to detect 'standing still' or 'squatting still'. For 'sitting still', wall mounting may be slightly better, but higher sensitivity and longer delay can improve ceiling mount performance.
• Montáž na stěnu: Can detect 'sitting still', 'standing still', and 'squatting still'.

Poloměr detekce:

• Presence detection radius: 1 ~ 3 meters
• Fretting detection radius: 5 ~ 7 meters

Large Area Inspection (approx. 20 square meters, e.g., lobby, living room):

• No Static Condition: Install in the center of the area for maximum coverage. If static scenes (e.g., sitting on a couch) are present, consider an additional presence device for that specific static area.
• Static Condition: For rooms around 20 square meters, install above the static human body's typical location. For areas larger than 20 square meters, add more presence devices for static areas, ensuring a spacing of more than 1.5 meters between devices.
• Over 20 Square Meters: Use an array method. The distance between each sensor should be less than the installation height. Refer to 'Sensor Boundary Settings' for specific boundaries.

Small Area Presence Detection (within 8 square meters, e.g., bedroom, bathroom, study):

Install the presence device as close as possible to where the human body is frequently stationary.

5. Údržba

To ensure the longevity and optimal performance of your WENZHI sensor, follow these simple maintenance guidelines:

• Čištění: Gently wipe the sensor's exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Umístění: Ensure the sensor is not obstructed by furniture, curtains, or other objects that could interfere with its detection capabilities.
• Napájení: For wall-mount sensors, ensure the USB power supply is stable. For ceiling-mount sensors, ensure stable AC power.

6. Řešení problémů

6.1 Často kladené otázky

Q1: The lights turn off while a person is still in the detection area, and only come on when the human body moves slightly.

Odpověď: This indicates that the sensitivity may be too low to accurately detect subtle presence. Please adjust the sensitivity setting in the Tuya Smart APP by increasing it by +1. Repeat if necessary until accurate breathing status is obtained.

Q2: The light stays on after a person leaves the detection area.

Odpověď: This suggests the unmanned delay time or sensitivity needs adjustment.

• Krok 1: Appropriately decrease the unmanned delay time. For short-term debugging, set it to 10 seconds. Once resolved, you can revert to your desired normal use time.
• Krok 2: After setting the unmanned delay to 10 seconds, gradually decrease the sensitivity by -1 until the light turns off after the person leaves.

8. Uživatelské tipy

• Optimalizace nastavení: Experiment with sensitivity and unmanned delay settings in the Tuya Smart APP to fine-tune detection for your specific environment and usage patterns.
• Consider Pet Interference: Be aware that pets might trigger the sensor if sensitivity is set too high, as the sensor detects micro-motion. Adjust sensitivity or placement accordingly.
• Placement for Static Presence: For detecting static presence (e.g., someone reading on a couch), wall-mounted sensors or ceiling-mounted sensors with increased sensitivity and delay are recommended, placed close to the static area.
• Vyhněte se překážkám: Ensure a clear line of sight for the sensor to maximize its detection range and accuracy.
