I have recently seen one of very interesting concepts and it's circuit diagram is present in the page: Electronic Plant Watering System. I felt that it is very useful in our real life also when we go for any tours.
Coming to my problem, I have a small in-house garden of size 130squre feet with lot of plants. I felt that this circuit is suitable for small place but not for large space like my garden. And also I think it takes lot of time to arrange this for my garden.
So, Can anybody suggest me is it suitable for 130 square feet size garden? And also, I would like to use LM555 timer instead of IC555 timer. What are the modifications to be done to this circuit to set up it to my garden? Are there any other circuits which is simple and suitable for my garden?
Kindly let me know your suggestions. Thanks in advance.
