The design of an efficient wind direction measurement using digital positioning method for smart house

摘要

The main purpose of this wind direction design is to produce the low price efficient wind direction measurement by using waste conductive material for smart house. We found that the input and output bit size is not necessary to equal the number of directions and it is able to be minimized and use simple electric circuit instead of integrated circuit. It is also reliable and easy maintenance. This paper shows the design of eight-direction design of measuring the wind direction by using 4-bit input and output which is consists of two plates, one is at the top plate and another one is at the bottom plate. The results are shown that 8 directions get different 8 values from 4-bit input which indicate different directions.
