I'm in the early process of trying to make an impact sensor for steel targets used in long range shooting competition.
At the moment I'm messing with what I hope is the easy route by using an Automotive Impact sensor. In fact it's This One. It not too expensive, and it's a simple mechanical sensor. That operates by having a "V" shaped cup mounted on a spring with a post that you can adjust in or out for sensitivity.
The way it works is that it has a + and a - line in and a sensor line out. The sensor line simply grounds the circuit when an impact is felt.
What I'm trying to figure out is the best way to make use of this information.
What I get is a very quick jump to the voltage I have applied. It's so quick that it doesn't allways show up on my multimeter, but if I hook it up to my digital O-Scope set for TTL input it picks it up every time.
So what would be your ideas on making use of this information. All I really want to do with it is to operate a relay that activates a camera flash.
As I said. I'm at the very beginning of working this out, so any and all ideas will be appreciated, including different sensor ideas. I have also considered using Piezo Vibration Sensor like THIS, but I think that might really complicate things.
Thanks for any ideas.
