Design and implementation of a small-size wireless data acquisition system

A small-size wireless data acquisition system is developed for the application where the common cable-necessary data acquisition system is inapplicable. The paper describes the design Issues and implementation of the system, especially on how to improve reliability and reduce the system volume. Questions on the noise and interference restraint are also discussed. The application of the system in practical experiments has shown that it satisfies the signal acquisition from rapidly revolving object. Besides, the small volume makes it ideal for space-critical measurement applications.
