    So I want to detect the height of an object using sensors.

    My thinking would be:

    Have a wall with 12 proximity sensors placed vertically over 12 inches.

    Place a cup next to the sensors. 8 Sensors are overlapped.

    Next I think that I would need a processor or cpu of some type to recognize the sensor detections and also know that 8 detections = 8 inches of height.

    Do I use a multiplexer to transmit the data to the CPU under one signal? Do I then use a demultiplexor to separate the signals for the CPU to process?

    Or is there another way?

    also, what is the generic symbol for a sensor?
