Introduction
The KSSTI 600/80 FG3LK-IBS is a capacitive level sensor that allows to control when a label is passing through it. This sensor is digital and normally must be handled with interrupts. In this case example is showed how to use this sensor using external interrupts.
Requirements
Ethernet PLC or 20 I/Os PLC: Ethernet PLC 20 I/Os PLC
KSSTI 600/80 FG3LK-IBS: KSSTI 600/80 FG3LK-IBS sensor
Industrial Power supply: Industrial Shields Accessories
Industrial Shields boards: Install Industrial Shields boards

Software
This simple sketch allows us to perform digital reading counting of the KSSTI 600/80 FG3LK-IBS label sensor every 1 sec. For this, we have used the input I0.5 of our M-Duino 21+. I0.5 allows external interrupt functionality, so we must add the attachInterrupt() function to set the interrupt functionality.
As a test, we will check the result monitored by the serial port, open the serial monitor to see the counting levels.
