7.Installation Notes
Radar Enclosure Requirements
If the radar requires an enclosure, the enclosure must have good wave-transmitting properties in the 24 GHz band and must not contain metal or be sensitive to electromagnetic waves.
wave shielded
The material of action. See the mmWave Sensor Radome Design Guidelines for more considerations.
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, and large green plants facing the air outlet.
