Data Logging With a Thermocouple

The project described here is a data recording program for the Phidget Temperature Sensors. We play with the program and record data to learn things about our environment.

Practical concepts covered are (click on links to see other projects on that topic): Data Logging Writing to a text file Adding timestamps to your data Using Phidgets with C/C++ Using Phidgets with Python Using Phidgets with Java Analyzing your Phidget Data

As with any of our described projects, Phidgets takes care of the electrical component design. Here, we also provide some simple code so you can play around with your Temperature Sensor and thermocouple, and save the data to plot later.

Time: About two hours

Special Needed Tools: A Phidget Temperature Sensor (1048 or 1051), a Thermocouple, a USB cord, and your computer.

• You should have already worked through our Phidget Temperature Sensor Getting Started Guide for your Temperature Sensor - this will show you how to get the the Phidget Libraries installed for your operating system.
• Your computer should have at least one of:
  • A a C compiler we support (including gcc, MinGW, Borland, Visual Studio, and many more)
  • A version of Python 2.6 or later, set up with the Python Phidget Libraries
  • A version of Java, set up with the Java Phidget Libraries
• If you would like to follow along with the graphing examples, you can install the R Statistical package, which is free and available for Windows, Mac, and Linux.
