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.
