[Three state sensing] Motion sensing and micro-motion sensing and existence sensing, accurately detect situations, not only sensing human movement, but also including: blinking, finger micro-movement, chest circumference changes during breathing and other movements. Within the detection range, no matter what posture you take, you cannot escape detection. [Sensitivity setting] Three levels of sensitivity adjustment are used to adapt to different product usage environments to avoid false alarms of the sensor when is there and missed alarms when someone is there. [WifiandBluetooth dual mode] Turn on the Bluetooth on the mobile phone, and the Bluetooth module can automatically search for for fast network configuration and connect to the APP faster. It is about 2 times faster than connecting to with only wifi single mode. Voltage:DC5V Current:Less than 1A Sensing angle:180 Sensing distance:0-5m Radar frequency:24.05-24.25GHz Transmitting power:2dBm Wireless type:2.4GHz Transmission rate:250Kbps Precautions: 1. Radar is an electromagnetic wave detection sensor. Moving metal and liquid will cause misjudgment such as: electric fans, pets close to the radar, shaking metal curtains, etc., and the installation location needs to be planned. 2. It is not suitable to face the air conditioner directly. The motor inside the air conditioner will cause radar misjudgment. 3. The radar action range is related to the target RCS, the material and thickness of the target cover. The effective action range of the radar will vary to a certain extent. 4. Bluetooth is only used for network signal connection, and Bluetooth cannot be used alone. WIFIandBluetooth is more stable.
