Automated tank filler project....

Hello friend I am hobbyist and I want to make a automated tank filler ... to fit in my tank.. because I don't have enough time to keep watch every time on my tank.. so I thought to make this project.... so that I can do freely my other work.. without worrying about tank...

I have attach the working of this project in the Flo-chart in my attachment...

And I want to make this using PIC micro-controller....

so please help... thanks in advance..

all you need is a level sensor and electronic valve thats all...

Good Morning...
Thanks Ajay Sir for reply.....

I want this complete project done by PIC MICRO-CONTROLLER because it's small and need less power and space.... i have got a link which is little bit related to this project.. :

And I hope it can done by some modification in circuit and code of this Christmas tree watering controller....

yusuf can you attach images here coz I am not able to see the circuit on that website. As I said important is to sense the level of water you have in your tank that will control whether its needed to turn pump on or off. If you can attach images here I can take a look then.

OK sir....

I have attach the circuit...

Please have a look...

It looks okay.
Why is the detector circuit for "pump running" different to "Pump off" and "Pump start " ?
Most 5 volt relays are low power so you may need to change to a 12/24 volt to switch a mains pump.

you might want to find another way to detect whether water is being pumped or not
the current method will not detect a loss of water after filling to the "pump running" level.

How about a temperature sensor on the pump as well in case it overheats ?
