iOlab
Siamo rivenditori ufficiali di iOlab un carrellino per eseguire diversi esperimenti di fisica prodotto da MacMillan Learning, che coprono diversi argomenti affrontati alle scuole secondarie di II grado.
Discover the innovative technology of iOlab, a built in sensors measure force, acceleration, velocity, displacement, magnetic field, rotation, light, sound, temperature, pressure, and voltages down to a few μV. Expansion connectors provide access to over a dozen user controllable digital and analog inputs and outputs. Free software controls the device, acquires and displays data in real time, and provides a suite of analysis and data manipulation features.
iOLab system overview
