A wireless multipoint pressure sensing system: design and operation

This paper describes the development of a remote-sensing and wireless data acquisition system. The system was developed as part of a research effort currently underway to instrument coastal homes in Florida to monitor roof wind pressures during hurricanes. However, the design of the wireless data acquisition is flexible enough to adapt to other multisensor, wind tunnel, or field-testing applications. This paper describes the details of the design, theory of operation, and the results of field performance tests of the system. The new system offers the advantages of ease of installation, capability for more than 48 h of continuous data acquisition from up to 60 sensors at variable sampling rate, and relatively easy maintenance.
