Introduction: Water Tank Alarm

About: hobbyist in DIY electronics
hi all of you it is my another project called water tank alarm that will sounds like birds when water tank is full and it will stops automatically when the pump is set off .it will reduce the over flow of water tanks in our homes.



components

transistor  BC 547      *2
                   BC  557      *1
resister      1 k              *2
                    10k             *2
                     56k            *1
capacitor    473  (.047)       *2
                     330/16v           *1
                     10/16v              *1

speaker       8ohms,5watt
10-15 inch of strong copper or iron wire
9 volt battery
copper winding wire (to make a audio transformer )
plastic box.

let's begin

    How to make audio transformer ?

    Can use 5 volt transformer

    like your projects, but they lack detailed instructions... you mentioned copper winding wire (to make a audio transformer ) but how to make it and what gauge of wire required?

    you can take a transformer from mosquito bat or CFL lamp

    circuit with the same Gage of copper wire and wind primary 400 turns and secondary 40 turns following 10 turns
    refer to the circuit diagram

    When simple ideas are combined it makes a better idea ! Thanks Instructables !

    I'd like your comments on my new submission.

    Your Idea is great and the circuit details provided are enough to make the electronics part.

    I would suggest a different scheme for the initiating contacts as keeping your suggested J-wire nodes in water for a long time would lead to corrosion and faulty operation.

    I built a similar system some time back and would like you to comment on this float based level sensor (water level switch)

    I am sure your circuit with this switch would be a great combination.

    hi sir i am very glad to meet you in instructables.com
    thanks for your comment and suggestion
    i like your water level switch really it will very helpful to me

    thank u

    your bird speaker is really quite adorable. is there anyway you can include details as to how to open your water heater, and comment on what the nodes are doing? I like the idea of this project, but i don't really understand how i could replicate it.

    thank you!

    nodes means two connecting poits that can act as a swicth to activate an electronic device. this are two points of a wire of continuty
    i made it with a strog sleved wire (called as J-wire ).
    soon i will post the procedure and other details

    i love u all. bye
