Hello. I'm an undergraduate working on a project to build a home
security system using DSP and NI's Speedy-33 board. My question is :
1) how can I detect breaking glass sound
using LabView?
2) how to connect external hardware(e.g
siren, lights) to the Speedy-33 board
that will be activated if breaking
glass is detected.
Thank you.
Update:
Hi guys. Thanks a lot for the excellent replies. This is actually a
Senior Design class and I'm assigned a project that uses DSP. Since
we have National Instrument's Speedy-33 board, it would be easier to
interface with it with Labview. What we're trying to build here is a
home security system that monitors(through microphones) a glass panel
to see if a break-in occurs.
I guess what I wanted to know is if there is a specific pattern for the
input that i will be getting off the microphone. because i think the
generated waveform really depends on how hard i hit it or even the
position on the glass where the contact occured.
More specifically, how can I use Labview to achieve this? Or what type
of signal processing methods would I have to undertake? I would say the
timeline that I have is about 2 months.
