The mic in the system constantly monitors sound level in environment. As soon as a spike in sound levels is detected in the environment this signal is monitored by the controller and it triggers an action. The DC motor is powered which rotates and so does the entire arm mechanism |

Flappingmechanism is used to move the Scarecrow arm in upward and downward direction. Their is a system that produces the sounds which scare the birds and other animals,With battery it will works and has camera to monitor the field. |
Scarecrow is normally used by farmers to save the crops from the bird |

This system senses the birds by PIR sensor and start to rotate the wings then iron stick hits iron plate and start to make the sound and it will stop automatically |
It is used to scare away the birds |
