Presence sensing is an X-band presence sensing radar module working at 5.8GHz. Based on the Doppler effect,
It is composed of a fixed-frequency, directional high-gain microstrip antenna and signal processing circuit and algorithm. The module size is: 24mm×18mm×1.6mm. Onboard integrated IF demodulation, spectrum energy analysis, signal amplification and digital processing technologies, this module can detects large movement signals such as walking, running, etc. of the human body in normal life, as well as small movement signals such as turning pages, typing, and swinging arms. It also detects
It can detect human breathing and other vital signs signals in resting states such as sleeping and sitting still, that is, detecting the presence of the human body, and can be used in various applications.
Used in many fields such as smart hotels, smart elderly care, smart lighting, smart security, smart homes, etc.
