Multible load sensors on one dummy

Projects General Guidance

Hi

Im a total nub so im hoping some nice person can help me with this.

Im thinking of building a strike and kick dummy to be able to measure the impacts power of strikes and kicks when doing combinations. I like it to use 10-20 sensors for diffrent parts of the boddy. Be able to display the data on a wall mounted screen, the data i like to se is the kg the strike have, say the last 5-10 hits for every sensor, the time between strikes on diffrent sensors. A bonus would be to be able to have lights next to the sensors for reaction training.

The sensors im thinging of is this one

Or this one

Or is a better option for this? Mabe a sensor that also can be used to se how the hit is made (if thay hit with fot or the bone in the legg and so on)

What do i need to get to be able to do this? Sensors,controllers, pcb, amplifier and so on, program to get the data displayed.

//regards

Study the output of the sensor You think about. Likely it shows with how much they are pressed momentarily. A kick would likely look like a soft mountain topp, an increasing value following some shape, reaching a maximum and the fading out. All is happening during less then a second.
Get Yourself one sensor and start testing. It will not be easy to evaluate such a signal.
Force is measured in Newton, not kilo.

Hmm the the sensors like this are used in project similar projekt but with one sensor,absolut power should be shown in N, but this shows in kg, and the strikebords we have today also shows it in kg.

The more important question is, is one better than the other for this project? And how to connect 10 or 20 sensors?

Likely made from some soft "ish" material that would absorb the impact.
Won't work, at least with any strain sensor.

The force of one kilo resting is 1 Kg times the gravity on the place used....

A lot depends on the mechanical aspect I'll say.

How do you mean? Is it the sensors that wont work?

But no one knows how to use multiple sensors of this type? or rather knows how to connect 10-20 off this sensors to a controller that can show the info on one screen?
