The Go Direct Rotary Motion Sensor measures angular motion. It connects wirelessly via Bluetooth® or wired via USB to your device.

Description

Monitor angular motion easily and precisely with the Go Direct Rotary Motion Sensor, which connects wirelessly via Bluetooth® or wired via USB to your device. The wireless connection eliminates the cables that can get caught and tangled during rotational investigations.

  • Determine position, velocity, and acceleration of objects in angular motion.
  • Measure angle increments as small as 0.25°.
  • Investigate rotational dynamics, conservation of angular momentum, pendulum motion, polarization of light, and more.

Rechargeable Battery—Ready When You Are

The Go Direct robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from our free Graphical Analysis 4 app. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wired or Wireless—The Flexibility to Choose

Our Go Direct sensors connect directly to your mobile device, Chromebook, or computer using our free Graphical Analysis 4 app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth, allowing you to choose the solution best for your classroom or laboratory.
