Frequently Asked Questions
Q. What is the Wulian Smart Human Presence Sensor?
The Wulian Smart Human Presence Sensor is an advanced smart home detector that utilizes high-frequency radar technology to identify human presence. Unlike standard motion sensors, it can detect micro-movements such as breathing, ensuring it knows when someone is in the room even if they are completely still.
Q. How does it differ from traditional PIR motion sensors?
Traditional PIR (Passive Infrared) sensors only detect active movement across their field of view. The Wulian Smart Human Presence Sensor detects static presence, meaning it will not turn off lights or automation systems while you are quietly reading, working, or sleeping.
Q. Does the sensor support smart home automation?
Yes, it integrates with smart home protocols (like Zigbee) to connect with your smart hub. You can configure custom automation scenes, such as turning on lights, adjusting thermostats, or activating alarms when presence is detected or when a room becomes vacant.
Q. Where is the best place to install the sensor?
For optimal coverage, it is recommended to install the sensor on the ceiling or high on a wall, facing the main area where people spend time. Ensure there are no large metallic objects blocking its direct line of sight to maximize detection accuracy.
Q. Is the radar technology safe for daily home use?
Absolutely. The sensor utilizes low-power millimeter-wave radar waves that are completely safe for humans, infants, and pets. Additionally, it respects your privacy as it does not capture any video or image feeds, making it ideal for bedrooms and bathrooms.
