1. Product description

The fall detection radar makes algorithm judgment based on the

characteristics of personnel attitude parameters. It detects the falling

state of the target person through changes in speed, distance, attitude

and other motions, continuously records whether the target is in danger

of falling, and responds to the stationary residence alarm for long-term

abnormal stay. This product is installed on the top of the kitchen and

bathroom. The fall/still dwell function detection is not affected by

factors such as temperature, humidity, noise airflow, dust, light, and

complete stillness of the human body.

7. Radar Installation Instructions

7.1. Working range of radar module

beam coverage of the R60AFD2 radar module is shown in the figure below.

The radar coverage is a three-dimensional sector of 100 ° horizontally

and 100 ° vertically.

R60AFD2 radar coverage area

7.2. Radar installation direction and detection range

7.2.1 Wall-mounted tilting installation

*To ensure the accuracy of radar detection, please install it at an

angle of 45° !

radar is installed obliquely, and the inclination angle is 45 ° to

ensure that the main beam of the radar covers the detection area; the

recommended installation height of the radar is 2 meters ≤ H ≤ 2.4

meters , and it is recommended to install 2.2 meters by default. There

are no obvious obstructions and coverings in front of the radar.

Affected by the installation height of the radar and the range of the

radar beam, in this installation mode, the maximum radius of moving

human detection is R 3 ≈ 2.5 meters; the maximum radius of human

stationary detection is L2 ≈ 2.5 meters ; the maximum radius of fall

detection is L1 ≈ 2 meters.

Detection range

wall-mounted tilt radar when detecting human activity is about 6 meters

* 10 meters, the detection range when the human body is stationary is 4

meters * 5 meters , and the detection range of human falling is 4 meters

* 4 meters .

8. Guide to the actual installation steps of the radar

Step 1 : Confirm the main activity area of the person ( fall detection

area) , the middle of this position is the installation position of the

radar

Step 2: Confirm the actual installation height of the radar, and set the

height of the radar according to the specific height

Step 3: Determine the entrance and exit of the space, and point the long

side of the radar to the entrance and exit to ensure the trigger effect

of people entering

Step 4 : Confirm whether there is any interference source within the radar

detection range

Step 5 : Confirm whether the real use scene of the radar is a

bathroom/kitchen/bedroom and other scenarios that need to consider fall

detection and stationary parking detection, and use the fall alarm and

stationary parking alarm functions accordingly

Step 6: Follow the steps to confirm the final settings for normal use

Space size: 3.5 ㎡ - 6 ㎡

Possible sources of interference: exhaust fans /metal shutters/ blackout

coated curtains

Installation orientation: the long side faces the door

9. Layout Requirements for Antenna and Housing

PCBA: Need to keep the height of the radar patch ≥ 1mm than other devices

Shell structure: It is necessary to maintain a distance of 3mm between the

radar antenna surface and the shell surface

Shell detection surface: non-metallic shell, need to be straight, avoid

curved surface, affect the performance of the entire scanning area.

10.Common problem

Interference factors: Radar is an electromagnetic wave detection sensor,

and active non-living will cause false alarms. The movement of metals,

liquids, can lead to false positives. Usually, electric fans, pets close

to the radar, and the shaking of metal curtains can cause false positives.

Radar needs to be planned in terms of installation angle.

Non-interfering factors: radar electromagnetic waves will penetrate human

clothing, curtains, thin wood, and glass. The installation angle and

performance of the radar need to be determined according to the application.

Semi-interference factor: Radar judges the existence of human body and is

not suitable for directly facing the air conditioner. The motor inside the

air conditioner can cause the radar to misjudge. It is required that the

radar product does not directly face the air conditioner. Or in the same

direction as the air conditioner.
