working as a comparator and the other IC 555 is working as a delay circuit below thworking as a comparator and the other IC 555 is working as a delay circuit. A relay switch is connected at the output of the circuit, which will get activated when any vibration is received by the PZT. The PZT is a peizo electric sensor which generates a very small abount of current when any vibration is received. The sensitivity of the circuit can be increase or decrease by increasing or decreasing the number of 10M variable resistors.

Here is a project of an ultra sensitive vibration sensor using CA3140 and a 555 timer IC.
The circuit can be used for variety of purposes for example vibration sensor, knock sensor etc. 
The circuit is using two ICs, both the ICs are performing different task in the circuit. The IC1 is
