Car theif

Mar 14, 2008 8 Replies

Hi All,



I need to design a wireless car theif detection device.


Purpose: When theif crack the car window, the device can detect it and then send out a SMS, or any other indication.



I know there are some kind of this devices, however, it is easy to use a frequency transmitter to disturbe the frequency.



So, I need to use GSM... and Bluetooth, I can handle bluetooth device easily.



What I need now is a sensor, do you have any easy/cheap/low power/ suggestion for me to connect phone and the connector ( because I can also program code in phone for send out SMS )


Thanks.



Best regards, Boki.


This sort of thing?

Isn't that a Toyota Corona?

Thanks, Fred.

Ultrasonics is how it is done....detecting change in inside air pressure.

No, it has too much spark for that boring old thing.

Proof positive that national loyalties mean more than real taste parameters.

It is one of the shittyest beers I have ever drank.

Here, in SoCal, it is popular among the latinos,and no, they do not know how to discuss taste or ingredient differences. They just want to shove a lime wedge into it and drink it.

The really sad thing is that since this Mexican produced piss water beer is an import, it gets priced like the premium beers here.

So funny. I have seen it back east far cheaper.

I wouldn't drink it if you paid me, however.

And i thought Corona was a nasty overpriced Mexican beer.

The problem is far worse than that. The immigrants could, for about the same price, drink Dos Equis, Negra Modelo, Bohemia or other decent products from the homeland. But no, it is popular with college kids, yuppie puppies, and other ignorant youths. They are just trying to "fit in".
