[IST, TU Graz, August 2018, Master Project by Peter Hohl] The goal of this project is to measure the pressure difference at certain points of interest in modern mainsails.
Therefore, small electronic devices were developed, which can be mounted on either side of the sail to measure the absolute barometric pressure difference.
The gathered values are transmitted via WLAN to a base station (e.g. a laptop or tablet) for further processing and direct feedback for the skipper.
