[Domestic self-developed] Office scene test! Firefly Factory CEM5855H domestic 24GHz millimeter wave radar module!

CEM5855H is a domestically produced 24GHz millimeter-wave radar module independently developed by Firefly Factory. Different from traditional induction radar modules that detect human movement or limb movements to determine the presence of a human body, the 24GHz millimeter-wave radar module also has the function of detecting small movements such as human breathing, making the detection more sensitive and accurate, and better meeting the needs of various application scenarios.

Compared with the large-scale movements of the human body, breathing detection is an important detection feature of the human body at this stage. However, the characteristics of breathing are slow and small, and when converted into electrical signal characteristics, they are extremely low-frequency discontinuous signal characteristics. At this time, compared with low-frequency radar, the higher carrier frequency of 24GHz naturally has an incomparable advantage in detecting such signals. The 24GHz millimeter-wave radar module realizes all-round human presence monitoring such as movement, micro-movement, breathing, and heartbeat.

Actual measurements in office scenarios show that the 24GHz radar module has sensitive detection, strong stability, and accurate status output.
