if you want to bring it up to kaitoke to do some destructive testing up to 200m I am happy to help. can shoot at it with 22LR, 223, 708 and 270

how does the sensor attach to the back of the plate ?

I have tested the radios on their own and got just under 10km out of them. When the transmit radio is mounted behind the steel plate, the signal get attenuated so I am hoping that more than 1000m will be possible. Will do some more range testing.

Yip, will definitely bring it to kaitoke - just need to do a bit more testing on it first, then I will build a couple more and we can shoot them till they give up

The sensor is mounted directly on the pcb. I’ve drilled two holes into the plate (bought off trademe) and threaded them. So the pcb is fixed inside the plastic enclosure, and the enclosure is bolted onto the plate. Enough of a shockwave gets transferred for the sensor to trigger with a lightish hit with a hammer against the plate.
