Installation conditions
Confirm the minimum installation clearance
If the radar needs to be installed with an enclosure, the enclosure must have good wave-
transmitting properties at 24GHz, and cannot contain metal materials or materials that can shield
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 constantly moving in the sensing area, such as
animals, curtains that continuously swing, and 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 a wall, external interference factors such as air conditioners and electric
fans at 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
• Make sure that 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. Metal shielding
cover or metal backplane can be used to shield the radar back lobe and reduce the influence 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 of the target's body shape, state, RCS,
etc., the target distance accuracy will fluctuate; at the same time, the maximum distance will also be slightly
fluctuation
