Automated Sprinkler System
With sprinkler systems, they can control when they come on and go off. But, they don't know about the temperature, the rain, or the wind. I created a controler, built off a Basic stamp one controller, this controls the sprinkler system based on temp. If the temp is below 36 degrees farenhiet the controller will drain the system and shut off the main valve. Below is a pic of the complete micro controller.
