Battery low voltage indicator 5v to 12v

This is simple battery low voltage indicator circuit which can be used in raspberry pi based battery powered projects where accidental shutdown of raspberry pi due to dicharging of battery below normal operating range can lead to corruption of data of raspberry pi computer, so by adding this circuit to your project you can avoid failure of your raspberry pi data by safely shutting down the pi when there is low voltage indication, so this circuit can be built with minimal component and very cheap but can save your expensive devices which are battery powered.By removing buzzer and adding a relay in it's place with a flyback diode one can switch heavier loads with it if they want to..
