How are smart sensors different from normal sensors? What are the advancements in this field? How to design and implement a proximity sensor for industrial applications?
I'm in search of a proximity sensor that can work efficiently in a range of 10 cm or more, with high response speed. Most important requirement is- it should detect the presence of human body through metal casing.
Is this a project for an industrial setting that has been assigned to you or a hypothetical assignment in school? If the former, what is your experience level?
What is your budget? Are there any other constraints (experience here says there often are)?
