ABSTRACT:
A shock and vibration detecting device comprising a sensor enclosed in an electromagnetic shielded and dust-proof case to send out a signal to an amplifying circuit constituted mainly by an operational amplifier once it picks up a shock and/or vibration signal. The output of the amplifying circuit is connected to a driving circuit to provide an output signal. A delaying circuit is used to lengthen the active period of the output signal. A voltage regulation circuit provides a regulated and filtered voltage to the above-mentioned circuits.
