1）Measure the falling speed of the human body  

2）Reside through stillness 

3）Image by point cloud

Alarm for a long time of motionless human body; Usually used in the bathroom, kitchen and other places that are not stationary for a long time.

Accurate recognition of lying posture, applicable to a wide range of scenarios.

Through real-time radar wave transmitting and receiving, relevant radar wave change signals are collected, and noise points are removed from the relevant changes.

The characteristic values were extracted according to the motion amplitude of respiratory heartbeat, and the output frequency was calculated to realize the real-time respiratory heartbeat numerical output

Millimeter wave radar can output human azimuth information in real time by collecting human direction and distance information. And have an accurate sense of both stationary and moving creatures.

The detection Angle accuracy is about 5° and the range accuracy is about 0.3m.

Millimeter wave radar simultaneously collects the direction and distance information of multiple targets, and outputs the number of people and location information in real time. And have an accurate sense of both stationary and moving creatures.

The detection Angle accuracy is about 5°, the range accuracy is about 0.3m, the maximum number of people detected is 10, the maximum number of real-time track tracking is 3, the minimum Angle of multi-detection is 20°, and the minimum distance is 0.5m.

In normal state, the radar will accurately judge the human body's sedentary state and the existence of sleep, and output information such as falls, breathing, and vital signs.

Phenomenon 1) The radar scanning area is large, and the movement of the doorway and the next door of the wooden wall is detected

             Adjustment method: reduce the radar sensitivity, and the radar provides scene settings.

Phenomenon 2) The underside of the radar is facing the running air conditioner and fan

             Adjustment method: Adjust the radar position, do not directly face the air conditioner or fan.

Phenomenon 3) Object shaking caused by air-conditioning wind

             Adjustment method: cotton, non-metallic items will not cause false alarms. Metal items need to be secured.

Phenomenon 4) The radar is not fixed, and the vibration causes false alarms

             Adjustment method: Avoid support shaking and vibration.

Phenomenon 5) Occasional moving objects such as pets and birds

             Adjustment method: Since the radar measures fretting and has high sensitivity, this interference cannot be ruled out.

Phenomenon 6) Power supply interference, resulting in occasional misjudgment

             Adjustment method: try to keep the power supply current stable and reduce the ripple.
