In fluid dynamics research, pressure measurements are of great importance to define
the flow field acting on aerodynamic surfaces. In fact the experimental approach is
fundamental to avoid the complexity of the mathematical models for predicting the
fluid phenomena.
It’s important to note that, using in-situ sensor to monitor pressure on large domains
with highly unsteady flows, several problems are encountered working with the
classical techniques due to the transducer cost, the intrusiveness, the time response
and the operating range.
An interesting approach for satisfying the previously reported sensor requirements is
to implement a sensor network capable of acquiring pressure data on aerodynamic
surface using a wireless communication system able to collect the pressure data with
the lowest environmental–invasion level possible.
In this thesis a wireless sensor network for fluid fields pressure has been designed,
built and tested.
To develop the system, a capacitive pressure sensor, based on polymeric membrane,
and read out circuitry, based on microcontroller, have been designed, built and
tested. The wireless communication has been performed using the Zensys Z-WAVE
platform, and network and data management have been implemented. Finally, the
full embedded system with antenna has been created.
As a proof of concept, the monitoring of pressure on the top of the mainsail in a sailboat
has been chosen as working example.
