Design 2D wind flow sensor with electronic field

This pattern is an innovate instrument for measuring 2D little weaker wind. The principle of the 2D little weaker wind measurement is based on creating a negative high voltage about -4KV in between four charged electrodes. When little weaker wind passes through the electric field, it will be shift and bias to some electrodes caused by the difference of electricity field. The circuit use SMD in order to reduce the size of the instrument for easy carrying. The experimental results shown that the instrument can measure little weaker wind to 0.1m/sec. The instrument is high effective, sensitive, precision and tiny, portable. The instrument can be used for sensing little air leaking. The respective fields such as air flight, energy industries, hospital separate room, and nuclear reaction laboratory, tunnel mining etc.
