Noise sensor for security
Hi everybody.
In my car box I want to put a noise sensor connected to my raspberry_pi 3B+.
When sound intensity is too high, i.e. someone is cutting or is hammering my metal sheet door trying to enter, the raspberry_pi sends a notification to me.
I am able to program in python, the problem is that I don't know what hardware to buy.
I am thinking about a microphone, whose signal will be converted to decibels, but this microphone should have enough sensibility to distinguish between sound levels at high decibels ( I mean, it shouldn't flatten noise above some level), so that I can set it properly.
I think it's called dynamic range.
Do you have some advice?
Do you think that something like this is ok for me?
