SUMMARY

The discussion centers on selecting an appropriate sensor to measure the distance between hands for a project in music production. The user seeks a solution that avoids interference from ambient noise and suggests using audio or ultrasonic sensors, such as a speaker and microphone setup. The Sharp GP2D15 IR distance measuring sensor is mentioned as a potential option, although concerns about its effectiveness in a noisy environment are raised. The user aims for a 3D measurement capability without relying solely on a transmit/receive system.

PREREQUISITES
  • Understanding of sensor types, specifically ultrasonic and infrared sensors
  • Basic knowledge of electrical engineering principles
  • Familiarity with audio signal processing
  • Experience with 3D spatial measurement techniques
NEXT STEPS
  • Research the capabilities and limitations of the Sharp GP2D15 IR distance measuring sensor
  • Explore ultrasonic distance measurement techniques and their applications
  • Learn about audio signal processing for distance measurement in noisy environments
  • Investigate 3D positioning systems and their integration in music production
USEFUL FOR

Electrical engineering students, audio engineers, and developers working on interactive music production projects that require precise hand distance measurement.

I am beginning a new project in which I plan on using the distance between my hands as a measurement. Being new to electrical engineering, I am not quite sure of what type of sensor to use to accomplish this. I would the sensor in one hand to only pick up the receiver in the other hand, not just pick up my other hand i.e. IR sensor. Please be descriptive and if possible suggest some further reading I could do on this subject.

Thank you

If you insist on having a transmit/receive sort of sensor maybe you could use audio or ultra-sonic pings: a speaker in one hand and a mic in the other?

Otherwise I would have recommended something like the Sharp GP2D15 IR distance measuring sensor...
 
I was thinking using audio to accomplish this but I would like to use this project for music production, hence there would be a lot of sound already in the room. I would like to be able to move my hands in a 3D fashion and be able to know the distance between them at all times.

It wouldn't have to be a transmit/receive system, I just thought it would be easiest. Any suggestions welcomed.

I should have included that in my first post, Sorry

Thanks for the quick response schip666,

Cheers
 
why not the IR system?
