atmega32-intelligent irrigation system

help me to write avr project for opening electrically controlled valve when the moisture content of the soil becomes less than the entered value??????????

As I tell everyone... You start by writing something... When you have some code we will help....

Exactly. This sounds like a very interesting little project, but you need to have something designed already. I've heard that these kind of home irrigation projects are very popular nowadays so you should find something using google.

How are you planning to measure the moisture?
What kind of valve do you have? How many valves do you have?
Is this your first microcontroller project? How skilled/experienced you are with electronics in general?

This is one of the projects a ways down on my list. There is at least one place on the net that show you how to make the blocks for measuring soil moisture.

Code should not be hard. Are you using c ?

hey, i got some sample code for that. compile this in win avr and add the AT commands you want to recognize in the

unsigned char test_text[20]={'C','m'};//enter here the text reply from the modem

here (see the program)

here's the sample dsn file (proteus)

if you mail me @

i will give you the code.

can u tell me....ur idea regarding this project.....what u want to do

I think the cats meow here would be to have the controller serve web pages. That way you could program it from your PC or smart phone. Make it faceless and maybe wifi. You could program or inspect a system with several of these controllers from one place.
