|
| Q7: How fast is the response speed of this radar? A: The radar can detect and report the presence of a human body within about 0.5 seconds, realizing real-time sensing of human presence. |
|
| Q8: Where should I install the sensor? A: It is recommended to install it on the ceiling, away from direct sunlight, heat sources, and strong air currents for optimal performance. |
|
| Q9: Can the detection sensitivity of this radar be adjusted? A：Yes, the radar provides 3 levels of sensitivity adjustment (High/Default/Low) for both stationary and motion detection, which can be set via the Tuya APP. |
|
| Q10: What should I do if the sensor doesn't connect to my Wi-Fi network? 1. Check the Basics Power: Ensure the sensor is properly powered. Wi - Fi Signal: Make sure the sensor is within range of your Wi - Fi router. 2. Reset the Sensor 3. Re - add the Device in the App 4. Check Router Settings 5. Update Router and App Firmware |
|
| Q11: Is this radar safe for human body? A: Yes, this radar has extremely low output power (≤10dBm), which will not cause any physical harm to the human body, and there is no risk of privacy leakage. |
|
| Q12: Does the sensor work with voice assistants? A: It supports Amazon Alexa and Google Assistant. |
|
| Q13. What if I can't connect it to the app? Ensure your WiFi network is working and the password is correct. Make sure the device is in pairing mode. If the problem persists, try resetting the device by pressing and holding the red button for a longer time (usually 10 - 15 seconds) and then attempt to connect again. |
|
