    i want to implement a vibration sensor that has a amgnet attached ona spring and a coil that gets the magnetic flux change converted to current. and then the current is amplified and a relay is switched... but i cant find the coil and the magnet piar anywhere from internet... i dont know what is this components special name etc.. but i have some oics that i would share if some one knows the name or some supplier plz tell me its name or from where can i buy this, the blue one is a coil .[​IMG]

    Welcome to CE dmsherazi,
    Can you state your points clearly so that other CEans can help you? Meanwhile have you tried attaching some links which would be useful in your explanation of your question?

    sorry for the bad quality of snaps, i will post new here
    this is for alarm systems, its used to check if someone try to hit the door or try to open it forcefully... the spring is the same as described by Steve

    the blue thing is a two terminal package for a coil, i had tried to tear open one and its just a coil wound on a plastic core. the concept is that the spring has a permanent magnet on it, when there are vibrations the spring makes the magnetic field to vibrate that induces some current in the coil, the signal is then amplified and through comparator fed to relay....

    this is marked L1 that means its an inductor, but i am just wondering if there is a pair for magnet value and the inductance value for optimum results, or is it just a separate inductor,

    how can i get optimum results?

    I don't know whats the function of this thing but you can use Accelerometer for vibration measurement.
