Hi evry1
I am trying to make a parallel plate capacitor , which am using to make a capacitive proximity sensor.
Question 1
I thought of making 2 plexiglass plates of dimension ( 90 X 50 X2.5 mm). An aluminium mesh is sandwiched between them. Now a positive voltage is supplied to aluminum mesh and the plexiglass plates is surrounded by another aluminium mesh such that the mesh between the plexiglass and this mesh is perpendicular to each other. This surrounded mesh is connected to ground.
Will such a combination work??
Question 2
Another option was to join 2 aluminium plates together with a piece of plexiglass as dilectric in between them.
How can i find the value of capacitance in both cases??
Thanks for any ideas
