Installation conditions

Confirm installation clearance

Before installing the radar, you need to test the installation gap between the antenna and the housing. When the housing is too close to the antenna, the radar reception will be saturated. However, the installation gap between different materials, different thicknesses, and different shapes of the housing and the radar antenna will be different.


Installation environment requirements

This product needs to be operated in a suitable installation environment. If it is operated in the following environment, the test results will be disturbed:

·There are non-human objects that move continuously 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 interfere with the radar antenna.


Precautions during installation

·When installing, make sure that the installation position of the sensor is firm and stable. The shaking of the radar itself will have a great influence on the signal processing.

·When installing, make sure that there is no object movement or vibration on the back of the radar. Due to the penetrating nature of radar radio frequency waves, the signal on the back of the antenna will also pass through the radar board. If there is an object moving on the back, it will also be collected by the antenna, which will affect the judgment effect. A radome or backplane can be used to reduce the impact of objects on the back of the radar.

·When installing, try to ensure that the radar antenna is facing the area to be detected, and the antenna is open and unobstructed.
