Tractor Beam
Newbie level 4
I am new here.
I am in need of a circuit to detect and warn me when 2 sheets of paper board (about 2 credit card thickness) and only 1 sheet is present.
I know a piezo transducer and receiver at 40 kHz is the correct frequency so I ordered the TCT40-16R/T piezo tranducer receiver pair.
The separation distance between the transducer and receiver will be 2 to 5 inches approx.
I have some electronics experience. I am familiar with the 555 timer, and the 2N2222 transistor, but not very good at designing circuits.
There are some devices out there but they want almost $600 for them which is beyond my budget.
