Matters needing attention: If a radar needs to be equipped with a casing, the casing must have good wave transmission characteristics in the 24GHz frequency band and must not contain metals or materials that have a shielding effect on electromagnetic waves 2. This product needs to be installed in a suitable environment. If used in the following environments, the detection effect will be affected 2.1 There are continuously moving non-human objects in the sensing area, such as animals, continuously swinging curtains, and large green plants facing the air vent. 2.2 There is a large area of strong reflection plane in the sensing area, and the strong reflection object directly facing the radar antenna can cause interference. When installing on the wall, external Confounding such as air conditioners and electric fans on the top of the room need to be considered. 3. Precautions during installation 3.1 Try to ensure that the radar antenna is directly facing the area to be detected, and that the surrounding area of the antenna is open and unobstructed. 3.2 To ensure that the installation position of the sensor is firm and stable, the shaking of the radar itself will affect the detection effect. 3.3 Ensure that there is no object movement or vibration on the back of the radar. Due to the penetrability of radar waves, the antenna back lobe may detect moving objects on the back of the radar. Metal shielding covers or metal backplates can be used to shield the radar backplate and reduce the impact of objects on the back of the radar. When there are multiple 24GHz frequency band radars, please do not align the beams and try to install them as far away as possible to avoid possible mutual interference. 3.5 Power precautions: The input voltage of the power supply is 5VDC, and there is no obvious spectral peak within 100 kHz of the power supply ripple. This plan is a reference design, and users need to consider corresponding electromagnetic compatibility designs such as ESD and lightning surge.
