Copper PAD as Cap Sensor
I need to install three input switches corresponding to which there are three LEDs that show the status of the switches.
I was certain to use macanical switches. But just got to know a bit more about the CAP SENSE capability of PSoc chips.
So m thinking to give a try to the CAPSENSE version.
There's a PCB containing three LEDs
Above the LED is 1mm thick diffusing epoxy
Above the epoxy is 1mm transparent glass. The user will touch this glass.
I want to make the capsense pads just below the LED. Size of pad is approx 4mmx2mm
A 3D photo is attached for better understanding.
Am I thinking in the correct direction or am I incorrect in the approch?
I have zero experience with cap sense.
