LD6001C is a 60GHz mmWave radar sensing module that can realize non-sensing active sensing monitoring of entrance and exit personnel all day long. Compared with traditional visual, infrared and other sensing methods, millimeter wave radar is not affected by light and has personal privacy protection function. The solution uses domestically produced chips and is self-controllable. When in use, the module can be installed on the top of the door entrance and exit, set the sensing range, and judge the entry and exit status according to the trajectory of people entering and leaving the sensing area to realize the counting function. Due to different batches, there may be differences in product appearance, color, and printed text, which will not affect the use.
