title: How to read temperature using arduino uno board with PT100 RTD sensor?
body: <p>I am new to arduino programming. And almost inexperienced.</p>
  
  <p>I am looking to program my arduino Uno board to read 2/3/4 wire configuration of PT100 RTD sensor (in accuracy levels of atleast 0.5°C). The temperature range is 0 to 400°C and -50 to 100°C.</p>
  
  <p>Since I am totally new to this field I would appreciate a rather descriptive information with circuits and images and code.</p>
  
  <p>I have researched a lot on the subject, but couldn't get anything useful or substantial to solve my problem.</p>
  
  <p>Moreover, I cannot use thermistor or any IC to read the temperatures as the machine on which the RTD is installed has PIDs, but I would like to create a datalogger that can fetch temperatures on computer itself.</p>
