1. A micro-motion warning device for a vehicle comprising:

  • a sensing portion comprising a housing which includes a tilt sensing ball which has a normal resting state at 22°

    with respect to horizontal axis, metal tilt switch contacts having contact resistance very close to zero and which remain open during normal operation, and a cover,wherein the housing and cover are made of polyamide and glass fiber, the ball is made of alloy plated over nickel and wherein the material used are ROHS (Restriction of Use of Hazardous Substances) compliant;

    a detection portion comprising a PNP transistor, a direct current source;

    a warning portion to alert people in vicinity and to call 911;

    false alarm preventing portion at least comprising a resistor, a diode, and a capacitor;

    a manually operated switch which controls operation of the false alarm preventing portion;

    the sensing portion, the detection portion, the warning portion and the false alarm preventing portion are in electrical communication with each other,wherein upon sensing external forces, caused by carjacking or occasional driving mistakes, by the sensing portion, an electrical signal is passed to a capacitor, then to the detection portion which detects and amplifies the electrical signal and finally passed to the warning device,upon receiving the electrical signal, an alarm can be generated by the warning portion,wherein if the manually operated switch is turned ON, the false alarm preventing portion takes over after a predetermined time of half a second, after the generation of the alarm, and shuts off the alarm,wherein if the external forces exist a predetermined time after the shut off, the alarm starts over again, the process is repeated until the external forces are stopped or the vehicle stops moving.
