This module describes the necessary steps for the construction of a low-cost photogate
that coupled to the PC or mobile device, the latter through the sound card, will allow
the measurement of time intervals with very high accuracy, precision and with appreciation
of the order of milliseconds and less.
Understand the physical foundations of photogate operation of the PhysicsSensor platform.
Explain how to use the PhysicsSensor platform photogate to measure time intervals using mobile devices (cell phone or tablet).
Describe the procedure to follow for the construction of the photogate of the PhysicsSensor platform.
There are two versions of the photogate to build. In version 1.0 it is constructed from PVC pipe cuttings. In version 2.0 it is built with 3D printing. You can choose either one and they work perfectly.In the following image on the left is version 1.0 and on the right is version 2.0.
