- APP Remote Control: Monitor your home's security from anywhere using the mobile application.
- Bewegingsdeteksje: Capable of detecting various human movements, from walking to subtle gestures.
- Statyske deteksje fan minsklike oanwêzigens: Advanced detection allows the sensor to identify human presence even when there is no active movement (e.g., sitting still).
- Aktiviteitslogboek: Review historical records of detected human presence directly through the app.
- Ferstelbere parameters: Customize settings such as detection distance and sensitivity via the mobile application.
- Scene Linkage: Integrate with other Tuya smart devices for automated actions (e.g., turning on lights when motion is detected).
- Alarm foar leech krêft: Receive notifications when the battery level is low, prompting a battery change.
- Wide-Angle Infrared Detection: Features a 105° horizontal and 105° vertical detection angle, with a maximum detection distance of 6 meters (20 feet).

- Slút de efterkant feilich.

Figure 5.1: The sensor is powered by AAA Alkaline batteries. Ensure batteries are installed correctly.
5.2 App-download en akkount oanmeitsje
- Download de Tuya Smart or Smart Life app fan 'e app store fan jo smartphone (iOS App Store of Google Play Store).
- Registrearje foar in nij akkount of meld jo oan as jo al ien hawwe.
5.3 Apparaatkoppeling
- Soargje derfoar dat jo smartphone ferbûn is mei in 2.4GHz WiFi-netwurk. The sensor does not support 5GHz WiFi.
- Iepenje de Tuya Smart of Smart Life app.
- Tik op it "+" ikoan yn 'e rjochter boppeste hoeke om in apparaat ta te foegjen.
- Select "Security & Video Surveillance" > "PIR Detector" or search for "Motion Sensor".
- Follow the on-screen instructions to put the sensor into pairing mode (usually involves pressing and holding a reset button until an indicator light flashes).
- Confirm the indicator light is flashing rapidly in the app and enter your 2.4GHz WiFi password.
- Wachtsje oant it apparaat ferbining makke hat. Sadree't it ferbûn is, kinne jo de sensor omneame en it oan in keamer tawize.
5.4 Montage fan de sensor
- Choose a suitable location for mounting. Consider areas where human movement is expected, such as hallways, entryways, or rooms.
- Ensure the chosen location is within the sensor's detection range (up to 6 meters) and has a clear line of sight.
- Reinigje it mounting oerflak yngeand.
- Peel off the protective film from the double-sided adhesive provided.
- Attach the adhesive to the back of the sensor and then firmly press the sensor onto the desired wall or surface.
6. Bedriuwsinstruksjes
6.1 Monitoaring op ôfstân fia app
Once paired, you can monitor the sensor's status and receive alerts directly on your smartphone through the Tuya Smart or Smart Life app. The app will display real-time notifications when motion or presence is detected.
6.2 Adjusting Sensor Parameters
Within the app, navigate to the sensor's settings to customize its behavior:
- PIR-gefoelichheid: Adjust the sensitivity level (e.g., Low, Middle, High) to prevent false alarms or ensure detection of subtle movements.
- Keep Time (Cooldown Time): Set the duration for which the sensor remains in a 'triggered' state after detection. This prevents repeated triggers within a short period. The shortest setting can be 30 seconds, and the longest 120 seconds.
- Motion Alarm: Enable or disable motion detection alerts.
- Notifikaasje foar legere batterij: Turn on/off alerts for low battery status.
- SMS/Phone Notification: Configure additional notification methods (may require subscription or specific regional services).

6.3 Scene Linkage with Other Smart Devices
Leverage the Tuya ecosystem to create smart scenes:
- In the app, go to the "Smart" or "Automation" section.
- Meitsje in nije automatisearring.
- Set the condition: "When device status changes" > select your motion sensor > "Motion detected".
- Set the action: "Run the device" > select another Tuya-compatible device (e.g., a smart light, smart curtain, or smart alarm) > define the action (e.g., "Turn On", "Open").
- Bewarje de automatisearring.
7. Underhâld
7.1 Batterijferfanging
When you receive a low battery notification from the app, or if the sensor's performance degrades, replace the AAA Alkaline batteries promptly. Refer to Section 5.1 for battery installation instructions.
7.2 Cleaning
To ensure optimal performance, periodically clean the sensor's lens with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the device.
8. Probleemoplossing
- Sensor detektearret gjin beweging:
- Check battery level in the app and replace if low.
- Ensure the sensor is mounted correctly and has a clear line of sight.
- Adjust PIR sensitivity settings in the app to a higher level.
- Wês bewust fan de cooldown time (Keep Time) setting. If the sensor was recently triggered, it will not re-trigger until the cooldown period has passed. This is normal operation.
- Faak falske alarmen:
- Adjust PIR sensitivity settings in the app to a lower level.
- Ensure the sensor is not facing direct sunlight, heat sources, or areas with significant air currents (e.g., near vents), which can cause false triggers.
- Sensor offline in app:
- Check your home's 2.4GHz WiFi network status.
- Soargje derfoar dat de sensor binnen it berik fan jo WiFi-router is.
- Kontrolearje it batterijnivo en ferfange as it nedich is.
- Try restarting the sensor by removing and reinserting batteries.
- If issues persist, try re-pairing the device with the app (refer to Section 5.3).

9. Wichtige notysjes en feilichheidsynformaasje
- This device requires a 2.4GHz WiFi-netwurk for connectivity. It is not compatible with 5GHz WiFi networks.
- The sensor has a built-in cooldown time (Keep Time) after each detection. During this period, the sensor will not re-trigger, even if further motion is detected. This is a standard feature to conserve battery life and prevent excessive notifications. The cooldown time can be adjusted in the app from 30 to 120 seconds.
- Stel it apparaat net bleat oan ekstreme temperatueren, direkt sinneljocht of hege fochtigens.
- Hâld it apparaat fuort fan sterke elektromagnetyske fjilden.
- Dit apparaat is allinich bedoeld foar gebrûk binnen.
- Besykje it apparaat net sels útinoar te heljen of te reparearjen. Nim kontakt op mei klanttsjinst as der problemen ûntsteane.
