- Control remoto de la aplicación: Monitor your home's security from anywhere using the mobile application.
- Detección de movimiento: Capable of detecting various human movements, from walking to subtle gestures.
- Static Human Presence Detection: Advanced detection allows the sensor to identify human presence even when there is no active movement (e.g., sitting still).
- Registro de actividad: Review historical records of detected human presence directly through the app.
- Parámetros ajustables: Customize settings such as detection distance and sensitivity via the mobile application.
- Enlace de escena: Integrate with other Tuya smart devices for automated actions (e.g., turning on lights when motion is detected).
- Alarma de baja potencia: Receive notifications when the battery level is low, prompting a battery change.
- Detección infrarroja de gran angular: Features a 105° horizontal and 105° vertical detection angle, with a maximum detection distance of 6 meters (20 feet).

Figure 5.1: The sensor is powered by AAA Alkaline batteries. Ensure batteries are installed correctly.
5.2 Descarga de la aplicación y creación de una cuenta
- Descargar el Tuya inteligente or Vida inteligente aplicación desde la tienda de aplicaciones de su teléfono inteligente (iOS App Store o Google Play Store).
- Regístrese para una nueva cuenta o inicie sesión si ya tiene una.
5.3 Emparejamiento de dispositivos
- Asegúrese de que su teléfono inteligente esté conectado a un Red WiFi de 2.4 GHz. The sensor does not support 5GHz WiFi.
- Abra la aplicación Tuya Smart o Smart Life.
- Toque el ícono "+" en la esquina superior derecha para agregar un dispositivo.
- 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.
- Espere a que el dispositivo se conecte. Una vez conectado, puede cambiar el nombre del sensor y asignarlo a una habitación.
5.4 Montaje del 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.
- Limpie bien la superficie de montaje.
- 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. Instrucciones de funcionamiento
6.1 Monitoreo remoto a través de la aplicación
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:
- Sensibilidad PIR: 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.
- Alarma de movimiento: Enable or disable motion detection alerts.
- Lower Battery Notification: 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.
- Crear una nueva automatización.
- 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").
- Guardar la automatización.
7. Mantenimiento
7.1 Reemplazo de batería
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 Limpieza
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. Solución de problemas
- El sensor no detecta movimiento:
- 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.
- Tenga en cuenta la 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.
- Falsas alarmas frecuentes:
- 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.
- Ensure the sensor is within range of your WiFi router.
- Verifique el nivel de la batería y reemplácela si es necesario.
- 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. Notas importantes e información de seguridad
- Este dispositivo requiere un Red WiFi de 2.4 GHz 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.
- No exponga el dispositivo a temperaturas extremas, luz solar directa o humedad alta.
- Mantenga el dispositivo alejado de campos electromagnéticos fuertes.
- Este dispositivo está diseñado únicamente para uso en interiores.
