    hello guys,
    what is the best sensor to monitor a movement? for example if something moves then a buzzer sounds if it stops then silent.
    i was thinking a tilt sensor like SW-520D but under specific situations then it doesnt work.
    is an accelerometer sensor good for this work?

    thanks a lot!

    What kind of movement do you want to detect?
    Would a vibration sensor work?

    i want to use it as pet tracker so if my pet moves then a buzzer will ring so i know where it is going...
    the idea was to use a vibration sensor but in some angles that sensor wouldnt work thats why im searching for something more accurate

    A vibration sensor should work better than a tilt switch.
    Are you trying to track it or just want to be aware of the movement?

    Is this for in the house, a specific room that you want to protect?
    Will the pet wear the buzzer and the sensor?
    Can you use a motion sensor?
    If the pet licks or chews to satisfy an itch the alarm could be going off almost continually.

    it would be in the garden so i a have made an waterproof case and the buzzer together with the board is inside it. thats why the sw520 for example is not good for the work because if the animal make that box go for example upside down then the sensor will not work

    I think what you want is a proximity alarm.

    a vibration is only going to tell you of movement ... to detect where the pet is or which direction its moving
    is going to require a lot more technology

    Hi Dave;
    I think what he wants to do is detect a pet that is trying to access his garden.
    There are still some unknown variables such as what the pet is and how confined the access is to the garden.
    If it's a dog then a buried dog fence would work, I don't know how well they work on a cat and I don't know if a goat would catch on to the idea.
    A motion detector or a beam might work.

    Kevin.
