#$%^&*AU2020101978A420201001.pdf#####Abstract of Description This invention discloses a compass based on the bionic polarization principle, which belongs to the design field of sensor used for navigation and direction finding. It is characterized in that the compass mainly includes the polarized light receiving module, photoelectric conversion and conditioning module, signal acquisition module, real-time clock module, signal processing module, communication interface and display module. The polarized light receiving module is used to receive the polarized light information in nature, and the photoelectric conversion and conditioning module converts the received polarized light signal into analog voltage signal; the signal processing module controls the signal acquisition module to collect the analog voltage signal output by the photoelectric conversion and conditioning module, calculates the azimuth information in combination with the time information provided by the real-time clock module, and outputs this azimuth information through the communication interface, which will be displayed on the LCD at the same time. This invention has the advantages of simple structure, reliable performance and high detection precision.Drawings of Description Polarized light Photoelectric conversion receiving module and conditioning module 110 120 Real-time clock module 140 Cmmnication teiiaceSignal acquisition intedface /.Signal processing unit sinlaqusto and display 150 module device- 130 EtMdcontrol module L160 Figure 1 +5V C3 6 IinI + 6 GND 3 Vout _F VOUT LOG104 8 8 Iin2 C18 _ _ C2 C4 -5V Figure 2 1/2
