GREEN BEE PROJECT DEVELOPMENT

i have gone through the GREEN BEE projects and i really feel we should have an extension , so everyone please give in your ideas and suggestions for making a really practical application !!!

sir, i wnt to ask that, can i add water level indicator in the well in this project?
using same microcontroller will it be possible or not?
as i m new in microcontroller i dont have much information regarding this...
so the green house owner can see the water level in the tank on the lcd..
please tell me will it be possible to add this in in house green house project ?

f i want to add this circuit in my project.. then please provide the circuit diagram and necessary additional code for it..
thank you....!!

@ vicky222
yes water level can be indicated using a micro controller or using any general ic

@ majoka; sir i want to add this in in house green house project..
can i do this on same circuit? along with all other sensors.. that is i am asking...

I am sure you will get some idea from this.

i use this once its work

@ajay and majoka:
thank you sir..:-)
i will try to add one more sensor in in house green house project.. i.e. Water level detector in tank..
From which water is given to crops..
Thank you.. Will try it..
And let u know..

finally some R&D on in house green house , good to see , if this doesnt work tell me , i will give u my circuit

@ph: thank you..!
Is ur circuit different?
Plz tell me..
Can you attach ur circuit here..?
