4.3 Pair the Sensor with the App

Follow these steps to connect your sensor to the Tuya Smart or Smart Life app:

1. Ensure your smartphone is connected to a 2.4GHz Wi-Fi network.
2. Open the Tuya Smart or Smart Life app and log in or create an account.
3. Press and hold the reset button on the sensor for approximately 5 seconds using a pin or a similar tool. The LED indicator on the sensor will begin to flash rapidly, indicating it is in pairing mode.
4. In the app, tap 'Add Device' or the '+' icon. The app should automatically discover the motion sensor. If not, select 'Add Manually' and choose 'Motion Sensor' from the list.
5. Follow the on-screen prompts to complete the pairing process, which may include confirming your Wi-Fi network and password.
6. Once successfully added, the sensor will appear in your device list in the app.

5. Installation

The Gaoducash Smart PIR Motion Sensor can be installed in various locations using either the provided adhesive film or screws.

5.1 Choosing a Location

Consider the following when selecting an installation spot:

• Detection Area: Place the sensor where its 128° detection angle and 6-40 feet range can effectively cover the desired area (e.g., corridors, doorways, garages, safes, rooms).
• Avoid Obstructions: Ensure there are no large objects blocking the sensor's field of view.
• Optimal Height: Install at a height that allows for optimal human motion detection, typically 6-8 feet (1.8-2.4 meters) from the floor.
• Environmental Factors: Avoid direct sunlight, heat sources, or areas with strong air currents, as these can cause false alarms.

5.2 Mounting Methods

Using Adhesive Film:

1. Clean the surface where you intend to mount the sensor.
2. Peel off the protective backing from the adhesive film.
3. Attach the film to the back of the sensor.
4. Press the sensor firmly onto the desired surface for at least 30 seconds.

Using Screws:

1. Mark the positions for the two screw holes on the mounting surface using the sensor's back plate as a guide.
2. Drill pilot holes if necessary.
3. Secure the sensor's back plate to the wall using the provided screws.
4. Slide the sensor onto the mounted back plate.

6. Operation

6.1 Real-time Monitoring and Notifications

Once installed and paired, the sensor will continuously monitor for motion. When motion is detected, the app will send an instant notification alert to your smartphone. You can view a history of all detected movements within the app.

6.2 Creating Smart Routines

Leverage the Tuya Smart/Smart Life app to create automated routines based on motion detection. This allows your motion sensor to trigger actions on other compatible smart devices.

Example Routines:

• Automatic Lighting: When motion is detected in a room, turn on smart lights.
• Security Alerts: If motion is detected when you are away, trigger a smart siren or send an alert to a security camera.
• Energy Saving: If no motion is detected for a set period, turn off lights or adjust smart thermostats.

7. Maintenance

7.1 Battery Replacement

The sensor will send a low battery notification to your app when the batteries need to be replaced. To replace them:

1. Slide open the back cover of the sensor.
2. Remove the old AAA batteries.
3. Insert two new AAA batteries, ensuring correct polarity.
4. Close the back cover securely.

7.2 Cleaning

To ensure optimal performance, periodically clean the sensor's lens and body with a soft, dry cloth. Avoid using abrasive cleaners or solvents.

8. Troubleshooting

• Sensor not connecting to Wi-Fi:
  Ensure your Wi-Fi network is 2.4GHz. Check that the sensor is within range of your Wi-Fi router. Verify your Wi-Fi password is entered correctly in the app. Try resetting the sensor and attempting the pairing process again.
• Delayed notifications:
  A slight delay (3-6 seconds) between motion detection and app notification can occur due to network latency. Ensure your Wi-Fi signal is strong and stable. Check for any app or device updates.
• False alarms:
  Review the sensor's placement. Avoid areas with direct sunlight, strong air currents (e.g., near vents), or rapidly changing temperatures. Ensure the detection area is clear of moving objects like curtains or pets if not desired to be detected. The sensor uses intelligent analysis algorithms to distinguish interference signals from human movement, but extreme conditions can still affect it.
• Motion not detected consistently:
  Check the sensor's orientation and height to ensure the detection area covers the desired path of movement. The detection range is 6-40 feet; ensure the target is within this range. Replace batteries if they are low.
• App not discovering device during pairing:
  Confirm the sensor's LED is flashing rapidly, indicating pairing mode. Ensure Bluetooth is enabled on your phone (some apps use Bluetooth for initial discovery before Wi-Fi connection). Try restarting your phone and the app.
