| Abstract: | This paper mainly introduces the principle, the design of hardware and software, and the entire application process of a kind of ultrosonic distance measureing system based on microcontroller AT89S52. It is mainly composed by the ultrosonic transmission circuit, the ultrosonic reception circuit and the display circuit. Precision is high and can clearly display the measuement result, so it is mainly applied in the automobile back-draft radar, the building construction work site, some industry scence position monitoring as well asavad able liquid position, well depth, pipeline length situation and so on. |
