Abstract

A working model for a thermal anemometry system compatible with the TSI brand probe and control box that provides a digital readout of both wind speed and direction was constructed. The design was intended to (1) eliminate the need for multi-axis readings by maintaining the probe always perpendicular to the wind direction, (2) eliminate some friction by incorporating optoelectronics to determine the wind direction within 45 degrees, (3) provide direct readout of wind speed in units of 1 mph on a bar graph display. Testing in a indoor environment yielded successful results with regard to directional measurements, and also made evident a need for further research into improved brush design to supply the probe with constant current through 360 degrees of rotation.
