Hello there,
I am sure this matter has been covered here before, but can't find it =
and would like your comments about the following:
I need to build a device that alarms when a seism takes places, prefer=
ably in an early state, let's say, for being used in public buildings or sc=
hools. It is not intended to measure and record the magnitud of the earth m=
ovement at all, just detect once it reaches certain level in any of the 3 a=
xis and activate a sound/visual indication.
As a first aproximation, I was taking a look to this IC: AIS326DQ http://www.st.com/stonline/products/literature/ds/14956/ais326dq.pdf,=
but honestly I have no practical criteria to determine in advance if =
it sensitive enough for my purpose. The manufacturer web page mention=
s it is for automotive applications, but my feeling is that the acceleratio=
ns changes in such environments are far beyond the ones I need to deal with=
..
In case you consider it not suittable for this application, could any =
of you, please, recommend some other chip?
I am located in Mexico City.
Thanks in advance,
Alexander
