Also I have messed around with the Arduino over the years and thought it would be a great tool for reporting the temperature, water use and closing the doors at night. I hope to use Zigbee to transmit the data back to a pc in the house, then display the data on a web page for remote viewing. The general dimensions are 4 feet by 3 feet with a height of 5 feet on the high side and 4 on the low. It will be raised 2 feet off the ground to keep the critters away and have less impact on the grass.
