Wasnt sure where to place this, so hope I have chosen the correct area.
I am trying to create a simple production counter that I can use in a VS2005 VB.Net project that I have.
What I would like is to have a sensor that can count the components that pass it, the components can either be Metal (Aluminium mostly), Cardboard or wood.
Now I would like the Sensor to be either USB or Ethernet, the count from the sensor to the VB.Net program must be in realtime because I also want to be able to have the program signal if the sensor has not seen a product after say 60 seconds.
If possible I would like the sensor to be able to be powered from the controller as I dont want to have sperate PSUs.
Can you recommend a set of components that will do what I need?
