If the radar needs to be fitted with an enclosure, the enclosure must have good wave-transmission characteristics in the 24 GHz band and must not contain metals or materials that have a shielding effect on electromagnetic waves; The presence of large strong reflective planes in the sensing area, strong reflective objects are directly in front of the radar antenna cause interference.When wall mounting, external interference factors such as air conditioners and electric fans on top of the room need to be considered. This product needs to be installed in a suitable environment, if it is used in the following environment, the detection effect be affected: -There are non-human objects with continuous movement in the sensing area, such as animals, continuously swinging curtains and large green plants directly facing the wind. Power supply considerations, power supply input voltage of 3.0V ~ 3.6V, power supply ripple within 100 kHz without significant peaks, this program is a reference design, users need to consider the corresponding ESD and For interface surge and other electromagnetic compatibility design., Weight: 0.0110231131 pounds, Manufacturer: susaa
