The BeeSpi v is a compact, battery powered photogate ready in one step!

Use the new BeeSpi v advanced self-contained photogate to measure free fall speeds, cars and projectile velocities. Two parallel photogates detect, measure, and display speeds of any objects that pass through, from zero to 99.99 km/h (measures in m/s too). Since it uses dual photogates, speed can be found with the object's front edge! No length measurement is needed. Try positioning BeeSpi v sensors at different points on an inclined plane, and calculate energy transformation from potential to kinetic. The gap is 40 mm x 30 mm, large enough to accommodate standard Hot Wheels cars and other small objects.

Additional settings measure lap time and cumulative lap time, so you can use BeeSpi to precisely measure the period of a pendulum. Requires two AAA batteries (not included). Single-button operation is a snap to learn, so your students will be collecting data in no time!
