Probeware is the combination of sensors and software connected to a computer or handheld device. At the heart of probeware is a digital sensor that measures a particular physical parameter. One or more sensors are plugged into an interface, a calculator, and a handheld device. With the click of a button, probeware collects and graphs data in real time—a graph forms or a table is populated with measurements as the data is collected. When students use digital sensors, they not only learn science content more efficiently, but also better learn the processes of science.
