 | | For any sensing application
various properties within the target area will change while the target event
occurs. | |
The choice of sensing technique to detect or measure the event will be one
that gives sufficient percentage change in response to the event yet whose
sensitivity, stability and clarity is least corrupted or compromised by other
influences in the environment.
Further requirements may include the need not to interfere with other
systems or sensors, or be detected by, or interfere with, other sensing systems
operating in the same environment. Levels of accuracy required and budget may
also play a part in determining optimum solutions.
