Whats the best method to give inputs to your logic circuits from long distance inputs like something over 30m length!! By use a transistor or opto or any other method??
Ex: I need to read a reed switch from a 5V logic circuit.The reed is place at 30m length.
What to use in the input circuit a transistor, opto etc....?
