Design and development of wind tracker

This work presents the attempt to design and develop a wind direction sensor base on temperature change by wind. Array of LM 35 temperature sensor with H/W has been used to indicate the wind direction. The proposed array is used on robot vehicle as the initial stage of plume tracking activity. The robot uses casting movement in form of zigzag motion to reach the wind source. In addition to tracking, the array can be used for metrological applications and environmental studies. This paper first describes the wind sensor array and the second part describes the experiments carried examine the stability and accuracy of design. Results obtained with various source distances and orientations are also reported.
