Installation Conditions

Confirm the minimum installation clearance

If the radar module needs to be installed in a shell, then the shell must have good wave permeability at 24 GHz and contain no metal or materials that may block electromagnetic waves.

Installation Environment Requirements

This module needs to be installed in a suitable environment. The detection effect will be affected if it's used in the following environments:

• There are continuously moving non-human objects in the sensing area, such as animals, plants, continuously swinging curtains, etc.
• There are large-area high-reflectivity objects in the sensing area; high-reflectivity objects will interfere with the radar antenna
• When it's installed on the wall, the indoor top-mounted air conditioner, electric fan and other external interference factors should be taken into account.

Precautions During Installation

• Try to ensure that the radar antenna is facing the detected area, and the surrounding area is open and unobstructed
• Ensure the sensor is installed firmly and stably as the shaking of the radar itself will affect the detection effect
• Ensure that there is no moving or shaking object at the back side of the radar. Due to the penetrability of radar waves, the back lobe of antenna may mistakenly detect the moving object at the back side of radar. So it is recommended to use a metal shield or metal plate to shield the back lobe to reduce the influence caused by the back object.
• The theoretical distance accuracy of the radar is obtained by special algorithm processing based on the distance resolution (0.2m or 0.75m). Due to the differences in the size, state, and RCS of objects, the distance may fluctuate, and so does the farthest detection distance.
