interfacing a sensor

sir ,contactless linear position sensor based on magnetostriction or optical nature or inductive sensor, anything sir. I just need a general idea of cost of the existing contactless linear position sensor.
thankyou

Most industrial transducers are very expensive and the vendors tend not to put the prices on line. You have to ask them for a quote like this one

hello,
i need to program my arduino to store a look up table, and as and when it reads a value from the sensor, it needs to go through the table and display the value if it finds a match in the table. can anyone provide some suggestion?..
thankyou

Yes several.

  1. Start your own thread with this question.
  2. Learn about arrays.
  3. Learn how to access each element in an array using a for loop.
  4. Think if you need or can have an array entry for every possible input value. Think about interpolating between two entries.
