Temperature sensor handbook

The temperature sensor is the first of the wireless networked sensor nodes in a series. They contrast with the actuators, of which the heat stick is the first.

If the history of technology can be characterized by increasing energy use, the invention of glass blowing and the alcohol thermometer would have been a good means both by which to economize the use of that energy as well as to investigate how to apply it to maximum effect.

A jeenode-agnostic tour of the principles can be found here.

As for applications to jeenodes, understanding the ports library and what it is will begin the process of understanding the jeenode (http://arduino.cc upon which its based is more foundational reading).

More foundations from jeelabs.

The idea in outline.

All of these plug into a JeeNode, thus making your very own analog electronic submersible temperature sensor!

Notebook

The notebook section provides a way for you to store and share information with your group members. With the book feature you can:

  • Add book pages and organize them hierarchically into different books.
  • Attach files to pages to share them with others.
  • Track changes that others have made and revert changes as necessary.
  • Archive books that are no longer of interest to the group. Archived books can be reactivated later if needed.
