The human presence sensor uses the principle of microwave radar and has the functions of detecting human presence, motionlessness, human micromovements and human movement. Thanks to mmWave Radar Detection technology, the device is able to detect the slightest movement, even breathing, hot flashes and sleep. P : Does the human presence sensor need a control panel (gate)? O : Yes, it is manufactured with the ZigBee protocol, so the Tuya ZigBee control panel is required. It acts as a central bridge for all Tuya ZigBee smart devices, providing an extremely stable signal and being an essential necessity for intelligent whole-home management. P : What is the difference between a human presence sensor and a PIR motion sensor? A : The intelligent human presence sensor is more sensitive and has more necessary functions in the app to explain the meaning of home security in the true sense of the word than the PIR motion sensor, it can even accurately detect a static state such as staff sleep. Functional intelligent human presence sensor ZigBee, PIR infrared sensors can only detect human movement, but are unable to detect when people are stationary and the risk of false alarm is serious. P : Can I set a detection delay to reduce the number of false positives? Answer . A: Yes, you can set the detection delay from 0 do 10 seconds to avoid irrelevant annoying movements. P : Can I set the wait time to provide the best detection function? O : Yes, there is a wait time set available in the app that allows for much more accurate detection. 【New design】 Set sensitivity from 1 do 10 according to your needs, as well as a minimum detection range of 0,00 m and a maximum of 10 m to ensure flexible detection requirements. At the same time, it was designed with a holding time set to 0 to 3600 s and a detection delay set to 0 to 10 s to avoid irrelevant annoying movements and reduce the number of false positives. 【Intelligent Connection】 Can create smart scenes together with Tuya switches, lamps, curtains and other smart products, providing energy saving, environmental protection, alarm safety and other functions. In combination with other smart devices, it can realize extensive automation and scene control. Make smart equipment respond faster and control more smoothly. 【Energy saving】 It can be used not only do detect moving objects, but also stationary ones. For example, the light in the kitchen turns on when you enter the do room and turns off when you leave. 【Remote control via the app】 The micro/macro motion detection feature allows you to detect human presence at a configured distance and receive real-time alerts through the app. 【Wide Application】 The motion microsensor can be widely used in lighting, security systems, household appliances, hotels, garages, buildings, transportation, LOT internet of things and other industries where it is necessary to detect human micromovements, motion and control detection distance.
