Temperature Probe

Contents

What is this?

Here is a simple easy to make temperature probe using easy to obtain components you may already have around. ^_^ It is perfect for interfacing with microcontrollers to provide temperature measuring ability.

  • no hard to find pieces
  • cheap and small sensor too
  • circuit is simple
  • mostly self explanitory, easy for beginners

For the diode probe use a piece of shrink wrap tubing for waterproofing

The results for my probe are plotted on the next graph
