Need an impact sensor for project
Hi Scotty The mass of the target is definitely fixed, but the user can vary their "seen" mass by using their whole body or just their arm, wrist, whatever, which is why I was thinking about another sensor. Punching technique varies by quite a lot, so I need to get an total force reading. It...- masamune

I agree that the target can still be hit incorrectly from a technical point of view, but as long as the total displacement of air can be related to the force generated, then that is ok. I know some people will not be able to strike properly that the way they strike will have an effect on how...- masamune

IRtuff - I think a pressure mat may be an expensive way to go? as I will need several of them. I am not up to speed on all of the available mats, but aren't they more juston/off type detector pads rather than proportional transducers? Warpspeed - I know what you mean now. It sounds similar to a...- masamune

Need an impact sensor for project
That's a very good idea. I was thinking along similar lines, as I don't think acceleration is very representative of how much "power" is actually in the punch i.e. how much resistance is needed to stop it. I would need a transducer that can handle, with accuracy, low power to very hard...- masamune

Interesting, Thanks for the reply. The ADXL 190/3 seem to be new additions to last years. I picked up an ADXL150 and didn't get around to using it as I didn't like it's max g rating. I might grab a few ADXL190/3s... Any tips on interfacing, reducing noise, effects of vibration, powering, A/D...- masamune

Need an impact sensor for project
Hi everyone, I am looking for a device to provide a signal output to a microcontroller (or maybe a PIC16f876/ etc) to get a useful reading to evaluate force exerted on a pad mounted on a stand. The idea is that a martial arts practicioner can strike this pad (and several others mounted at...- masamune
