Material Sensors

[Siddhant Chawla]

I'd like to know which would be the best sensors to use to detect materials (plastic. glass metal and paper) and where can I get it? My research says capacitive and/or ultra sound sensors are good, but I cannot find anything conclusive.

A lot depends on how you use the sensors - you could use light-based sensors to detect plastic (of the clear/translucent variety) and magnetic for 'some' metals.

Define the method you want to use first - then find the sensors to fit.

Differentiating between the metals is the easiest . . . .but the ABSOLUTE subtle variants in the last three , will probably be best served by CHEEEEEEEEEEEP labor with the eye evaluation . . . brain processing and final manual separation.
