An electronic weather vane for field science

Abstract

This paper details the construction of a weather vane for the measurement of wind direction in field situations. The purpose of its construction was to analyse how wind direction affected the attractiveness of an insect pheromone in a dynamic outdoor environment, where wind could be a significant contributor to odour movement. The apparatus described provides a cheap and easy to construct alternative to commercial wind vanes, and was shown to provide accurate and continuous measurement of wind direction.
