Tilt/Vibration Sensor

[pedja089]

Most of car alarms use coil and magnet on spring, signal from coil is goes to comparator, output to monostable.
This way you can set trigger level, and you can define duration of output signal.
In stand of coil, magnet and spring you can use piezo.

No in my case. PIC must be in sleep mode until a clear TTL level trigger wakes it up.

So, anything like a switch can be used. Not analog senors.

Thanks for the input.

I am waiting for the new spring sensors and also trying ways with the ball sensor.
