Conclusion

This proximity sensor guideline gives some indications of which parameters to consider

when developing a proximity application.

The deal is to find the best compromise between sensitivity, stability, and immunity to noise.

Depending on the application constraints, environmental change, board design constraints,

and power supply, many considerations should be take into account, including:

•

Define electrode design.

•

Evaluate environmental constraints

•

Use a shielding to bring detection directivity.

•

Determine device internal parameters to optimize system performance and stability.

The best practice is to develop a prototyping device as similar as possible to the final design

in order to be able to already integrate all system constraints during engineering phase.
