Capacitive and Inductive sensors for arduino

Hi,

I want to make a project which will verify the existance of plus 80 manual tools in a carboard. What i have trouble to decide is what type of sensors i am going to use. For my search i couldn´t find any inductive or capacitive sensors modules for arduino. Can you please help me find the best solution (sensor) for this?

Many sensors (and electronic components in general) will work fine with Arduino even if they aren't specifically advertised as being for Arduino.
