Wireless Pressure Sensing During Florida 2004 Hurricanes

Abstract eng:
A wireless multi-point sensor remote sensing system designed and developed for monitoring windstorm pressures on coastal residential structures was deployed during the 2004 hurricane season. Twenty four sensors (23 pressure units plus an anemometer) were installed in an hour on a house roof top to gather the data and sent it to a 10 m distant base collector continuously for up to 48 hours during the hurricane events. After a brief description of the wireless sensor system, results of time series variations of wind speed, direction, roof pressures, as well as the pressure and velocity auto- and cross-correlations, and gust structure for these hurricanes are described here. The 3-s gust factors are for found to be slightly higher than the ASCE prescribed values
