I got a slight issue. I had connected flow sensor to out microelectronic using the following circuit. The sensor was simply outputting a pulse. "Input 1" connects to the GPIO pin of my AVE and "Input_Control 1" is the output of the sensor.
The sensor has been removed, but the wire which about 1.5 meters is till connected to this circuit and then the GPIO.
We are detecting pulse on that GPIO. We are monitoring the pulse using a counter variable that is TX using the internet.
Is this normally behaviour?
