If you want to avoid birds from your farm then this circuit helps to scare the birds and makes them to avoid the farm.
Circuit diagram
This circuit uses 6V/300mA solar panel and Timer IC555, this circuit continuously produce sound using buzzer at the KHz range so this sound scares birds. The SLA battery charges during day time using the power out from solar panel and during night time this battery reacts as power source for the circuit.

Can i use a sensor? so that sound is produced only when motion of bird is sensed. If yes then how can i include in this circuit? Also can i use an mp3 and loud speaker instead of buzzer? Please reply
Thank you for your interest!
Yes Ofcourse, you can use PIR motion sensor in this circuit, If you do make trigger pin2 of timer ic as a input(that is pir output pin to trigger pin2) and you can bias output as key by adding switching transistor or relay to connect mp3.

If i use a pir Sensor then it require 9volts and Solar Panel providng 6volts then What should i do
I think +5V is good enough to PIR sensor, in case you need more voltage you can use voltage booster circuit.
Can you explain me the whole working and design of the circuit because I’ve considered implementing this as my next project for my internal laboratory exam ?
Would you please help me by uploading the working and design ?
Can I know what is the value of frequency being release by this ckt?
Can i use tweeter instead of buzzer?
Plz reply…
buzzer gives loud sound, you can try tweeter also.
