One of our newest products is the Vernier EasyTemp. EasyTemp is a rugged, general-purpose temperature sensor that you can plug directly to the USB port of a TI-84 Plus or TI-84 Plus Silver Edition calculator. You can then take temperature measurements directly with the calculator. Its durability and temperature range (-20°C to 110°C) make it perfect for a variety of activities in science and math. Typical uses include monitoring temperature in

• weather studies
• chemical reactions
• cooling curves

• insulation studies
• specific heat experiments
• heat of fusion experiments

EasyTemp has a mini-A USB connector that allows you to attach the temperature probe directly to the USB port of a TI-84 Plus or TI-84 Plus Silver Edition calculator. You can then take temperature measurements directly with the calculator. EasyTemp comes with two labs, but more free labs can be downloaded from our web site at www.vernier.com/easy/easytemp.html.

While we were designing EasyTemp, we developed a new data collection program called Vernier EasyData™, which is compatible with the TI-83 Plus and TI-84 Plus families of calculators. EasyData was primarily developed to support data collection with sensors that connect to the USB port of the TI-84 Plus and TI-84 Plus Silver Edition calculators. Those sensors include EasyTemp and the CBR 2™, TI’s calculator-based USB motion detector. The EasyData application can also be used with LabPro or CBL 2 and a wide range of sensors, e.g., pH, Oxygen Gas, Dual-Range Force, etc. EasyData brings a new level of simplicity to calculator-based data collection. Program navigation is performed using the five graph keys, located directly below the graph screen, making data collection simple and fast. Program options are displayed in pop-up dialog boxes or simple wizards. Below are sample screen shots from the program.

When you use EasyData with EasyTemp, data collection couldn’t be easier. All you have to do is turn on the calculator, plug in the EasyTemp, and EasyData will automatically launch, preparing you to collect data. It’s that easy!

EasyData comes preloaded on TI-84 Plus and TI-84 Plus Silver Edition calculators manufactured after January, 2005. If you have a TI-84 Plus manufactured before then or if you have a TI-83 Plus calculator, EasyData is a free download from our web site at www.vernier.com/easy. Give it a try!
