- No Hub Required: Connects directly to your 2.4 GHz Wi-Fi network, simplifying setup.
- Mobile App Control: Compatible with TuyaSmart or Smart Life applications for remote control, scene linkage, and real-time presence monitoring.
- Wide Detection Range: Supports a maximum detection height of 3 meters and a maximum detection range of 6 meters with a 120° detection angle.
- Customizable Settings: Adjustable parameters via the app, including light value (10lux, 20lux, 50lux, 24H), light duration (3-10s), and detection distance (1.5-6m).
- Privacy Protection: Operates without a camera, ensuring user privacy.
- Embedded Installation: Designed for convenient ceiling installation.
4. Safety Information
WARNING: This device requires direct wiring to an AC 95-250V/60Hz power source. Improper installation can lead to electrical shock, fire, or damage to the device. Installation should only be performed by a qualified electrician or an individual with a thorough understanding of electrical wiring and safety procedures. Always turn off power at the circuit breaker before beginning any wiring work.
- Ensure the power supply is disconnected before installation or maintenance.
- Verify correct wiring connections according to the provided diagram to prevent damage to the sensor or connected devices.
- Do not expose the device to moisture or extreme temperatures.
- Avoid installing near moving objects such as curtains, plants, or pets to prevent false alarms.
- The wiring block is designed for small gauge wires. Ensure wires are cleanly and securely inserted.
5. Setup and Installation
5.1 Wiring Instructions
The sensor requires a continuous AC 95-250V power supply. Refer to the wiring diagram below for proper connection. Ensure all connections are secure and insulated.
Figure 5.1: Wiring diagram for connecting the sensor to an AC power source and various light fixtures. The diagram illustrates input (AC95-250V) and output (AC95-250V, 2A) terminals, showing connections for fluorescent tubes, table lamps, incandescent lights, chandeliers, and floor lamps.
5.2 Mounting the Sensor
The sensor is designed for embedded ceiling installation. The maximum recommended installation height is 3 meters. For optimal performance, avoid placing the sensor near objects that move frequently, such as curtains or large plants, as this can cause false detections.

5.3 App Connection
The Haozee Human Presence Sensor connects directly to your 2.4 GHz Wi-Fi network. Follow these steps to connect the sensor to the mobile application:
- Download the TuyaSmart or Smart Life app from your mobile device's app store.
- Register or log in to your account.
- Ensure your mobile device is connected to a 2.4 GHz Wi-Fi network.
- Power on the sensor. The LED indicator will flash, indicating it is in pairing mode.
- In the app, tap the "+" icon to add a new device.
- Select the appropriate device type (e.g., "Sensor" or "Presence Sensor").
- Follow the on-screen instructions to complete the pairing process, entering your Wi-Fi credentials when prompted.
- Once connected, the sensor will appear in your device list, and you can begin configuring its settings.

6. Operating Instructions
Once installed and connected to the app, you can customize the sensor's behavior to suit your needs.
6.1 App Settings
Within the TuyaSmart or Smart Life app, navigate to the sensor's settings page to adjust various parameters:
- Detection Distance: Adjust the maximum range for presence detection from 1.5 meters to 6 meters.
- Illumination Value (Lux): Set the ambient light threshold for light control. Options typically include 10lux, 20lux, 50lux, or 24H (always active regardless of light).
- Light Duration (Presence Time): Configure the delay (3-10 seconds) before connected lights turn off after presence is no longer detected.
- Motion Detection Sensitivity: Adjust the sensitivity for detecting movement.
- Motionless Detection Sensitivity: Adjust the sensitivity for detecting stationary presence.

6.2 Output Modes
The sensor supports two output modes:
- Automatic Mode: The sensor automatically controls connected lights based on presence detection and configured settings (lux, duration).
- Manual Mode: Allows for manual override or specific scene linkages through the app, independent of automatic detection.

7. Maintenance
- Cleaning: Gently wipe the sensor's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Firmware Updates: Check the TuyaSmart or Smart Life app periodically for any available firmware updates to ensure optimal performance and access to new features.
- Environmental Conditions: Ensure the sensor is not exposed to direct water spray, high humidity, or extreme temperatures outside its operating range.
8. Troubleshooting
- Sensor Not Connecting to Wi-Fi:
- Ensure your Wi-Fi network is 2.4 GHz. The sensor does not support 5 GHz networks.
- Check that the sensor is within range of your Wi-Fi router.
- Verify correct Wi-Fi password entry in the app.
- Try resetting the sensor (refer to app instructions for reset procedure) and re-pairing.
- False Detections or No Detection:
- Review the installation location. Ensure there are no moving objects (curtains, plants, fans) within the detection zone.
- Adjust the detection distance and sensitivity settings in the app.
- Ensure the sensor is mounted at an appropriate height (max 3 meters).
- Check for any obstructions blocking the sensor's field of view.
- Lights Not Turning On/Off:
- Verify the wiring connections are correct and secure.
- Check the illumination value (Lux) setting in the app. If set too high, lights may not activate in bright conditions.
- Ensure the light duration (Presence Time) is set appropriately.
- Confirm the sensor is detecting presence correctly in the app.
- Device Not Responding:
- Check the power supply to the sensor.
- Restart the sensor by cycling its power.
- Ensure your mobile app is up to date.
