Effective solutions in 

Often there will appear to be easy solutions to a sensing problem in that numerous devices exist for the type of measurement required. However making a choice can now, perversely, be more difficult. What accuracy, repeatability, power consumption, size, interface, packaging etc. are required, and at what cost ? Interpreting device specifications can be a black art, especially when different parameters are listed by different manufacturers.

Experience in this area is particularly crucial when specifying for medium/high volume applications, and also when an application is very demanding. Generation of a short list will enable a sensible test comparison to be made after acquiring examples of each sensor.
