We are excited to announce a new sensor for physics—Go Direct Photogate. With our first-ever wireless photogate, you get better-than-stopwatch timing accuracy of a cart traveling eight or more meters without having to run wires between the gates. And that is not even its best feature.
Go Direct® Photogate is actually three photogates in one. The interior arms of the photogate include two photodiodes. This double-gate design measures velocity more accurately in comparison to single-gate photogates. The known separation of the gates makes it possible to measure speed without concern for the object’s geometry or knowing its dimensions. The direction of motion is indicated by positive or negative velocities determined by the order in which the internal gates are blocked. For objects that have two or more flags, the acceleration of the object through the gate can be reported as well. You can also use the internal gates independently for experiments that utilize traditional photogate modes, such as motion and pendulum timing.
The third photogate is a laser gate that you can use with a laser pointer (not included) to make a single gate that is any width. This is useful when dealing with larger objects that cannot pass between the interior arms of the photogate.
There are two optional accessory cables for the Go Direct Photogate, each sold separately. Use a Go Direct Photogate Timing Cable to daisy-chain two Go Direct Photogates together. This configuration makes the two Go Direct Photogates work using a single clock, which can improve timing accuracy by up to 10 ms. Use the Go Direct Time of Flight Pad Cable to connect a Time of Flight Pad to a Go Direct Photogate for use in projectile motion experiments.
Collect sound data wirelessly with the snap of your fingers. With sound-triggered data collection, Go Direct® Sound provides students with an easy way to capture and evaluate waveforms. Measure wave amplitude and sound intensity level at the same time to investigate the decibel scale, or take the sensor outside the classroom to discover sounds in their natural environment.
We’re very excited about this release as it includes support for photogates in the most common modes of motion, gate, and pulse timing. It is also the first release of the Android version, which adds support for Go Direct® sensors!
