DIY Arduino 6-channel temperature monitor

Johnathan Hottell wanted a way to monitor and display the temperature readings at various points around the engine on his LB7 Duramax diesel truck. He developed this project for a six channel temperature monitor employing a bank of thermistors to monitor various engine locations. They are read each second by the Arduino’s analog pins, with the values interpreted and temperatures displayed on a Nokia 3310 LCD screen.

He notes: “A commercial style temperature scanner can cost hundreds of dollars, this project minimizes that cost.” This is a good example of the cost savings that can be realized using a DIY open source solution.

The schematic, Arduino sketch and LCD library can be found on Johnathan’s website. Additional coverage and a BOM can be found on the Jameco project page.

  1. To save board space you can also use 1-wire bus and supporting sensors and just daisychain them. Of course installation can be trickier in certain places that way.

  2. Your devices develop a HACCP compliant survey each day. This particular survey is actually stored in an electronic form which often can and then end up being printed for the challenging duplicate reference. Reviews for just about any noted time might be made immediately on the base stop without notice.
