4X 24G mmWave LD2420 Human Presence Sensor Motion Detection Module

4X 24G mmWave LD2420 Human Presence Sensor Motion Detection Module Popis

If the 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 electromagnetic waves;
This product needs to be installed in a suitable environment, if it is used in the following environment, the detection effect will 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.
The presence of large strong reflective planes in the sensing area, strong reflective objects are directly in front of the antenna will cause interference.When wall mounting, external interference factors such as air conditioners and electric fans top of the room need to be considered.
Power supply considerations, power supply input voltage of 3.0V ~ 3.6V, power supply ripple within 100 kHz without significant spectral peaks, this program is a reference design, users need to consider the corresponding ESD and For interface surge and other electromagnetic compatibility design.
