Irrigation

Wendy and I are making a effort to get our mornings back. After

planting fruits and vegetables all over our yard we realized we were

giving up a hour every other day to water our crops. We started to

look at commercial irrigation systems, but they are incredibly lame.

They cost hundreds of dollars for what is basically a few solenoid

valves and a $3 microcontroller. I said forget that. We can roll our

own that is much smarter! Tonight I did some conductivity tests and

found that I can use the analog digital converter on my own $3

microcontroller and measure how wet the ground is. This means our

water system will not be based on timers. It will just water the

trees and plants when it gets a dry reading from the soil. In other

words you will not see our drip system flooding the yard during a

rain storm.
