RKB1126 is a highly sensitive 24GHz millimeter wave human body micro motion detection radar module. Unlike traditional radar, which detects large movements or limb movements of the human body to determine the presence of the human body, the main feature of this module is that it has the function of detecting the accumulation of micro motion amplitude of the human body based on the function of traditional human body induction radar. Therefore, compared to traditional Doppler radar, it has a certain range of presence detection and higher accuracy. Not easily overlooked. The module can penetrate non-metallic shells without the need for openings. Common materials include plastic, glass, wood, ceramics, etc. Especially for human presence detection applications, it is recommended to install plastic 86 box panels on the wall and suspended ceiling buckle shells on the ceiling.
