From time to time, readers will reach out to us for help on a specific project. Sometimes we know the answer. Sometimes it’s better put to the community. Jim B. wrote to ask about measuring high-speed collisions for his science class:

I am a junior high science and health teacher working on a project where the students would like to measure the velocity of impact on a pipe and see the rate of collision in real time, with triaxial data points in kilometers per hour. We want to collect data on the effects of high-speed collisions and transmit it wirelessly, including the dynamic behavior of the projectile bouncing off a stationary pipe (or other metal surface). I was wondering which effective tools existed to measure and record such impacts and responses.

We’re not sure what are the best accelerometers or sensors are to measure it, or the best way to simulate this project with a wireless components feature. These are the items or subject matter the class is researching on the computer for help with project.

  • Power sources, including voltage
  • Data, and 3-axis sensing data
  • Plug-n-play would be great
  • Telemetric using a high sensitivity ISM Datum wireless network, enabling long distance network wireless sports and hardwired sensors
  • Data acquisition
  • Logic/relay interface
  • Large data displays
  • A unique embedded 32 bit identification code

The students and I want to deeply thank you for your advice and efforts to propel our project forward as each of them strive to reach their accolades in the STEM program.

Best wishes and continued success in all your future endeavors!

Cheers,
Jim
