5.5 Installation conditions

 Confirm the minimum installation clearance

If the radar needs to be installed with a casing, the casing must have good wave-transmitting

properties at 24GHz, and cannot contain metal materials or materials that have a shielding effect on

electromagnetic waves.

 Installation environment requirements

This product needs to be installed in a suitable environment. If it is used in the following

environments, the detection effect will be affected:

• There are non-human objects that are continuously moving in the sensing area, such as animals,

continuously swinging curtains, large green plants facing the air outlet, etc.

• There is a large area of strong reflectors in the sensing area, and the strong reflectors will cause

interference to the radar antenna.

• When installing on the wall, external interference factors such as air conditioners and electric

fans on the top of the room need to be considered.

 Precautions during installation

• Try to ensure that the radar antenna is facing the area to be detected, and the surrounding area of

the antenna is open and unobstructed

• To ensure that the installation position of the sensor is firm and stable, the shaking of the radar

itself will affect the detection effect.

• To ensure there is no movement or vibration on the back of the radar. Due to the penetrating

nature of radar waves, the back lobe of the antenna signal may detect moving objects behind the

radar. A metal shield or metal backplane can be used to shield the radar back lobe and reduce the

impact of objects on the back of the radar

• The theoretical distance accuracy of radar is the result obtained through special algorithm

processing on the basis of the physical resolution of 0.75 meters. Due to the difference in the size,

state, and RCS of the target, the target distance accuracy will fluctuate; at the same time, the longest

distance will also fluctuate slightly.
