Optimize garden water use for savings and plants

Is your lawn or garden on a timer? Do you manually water? Do you research the weather to see how much it is going to rain before watering? Finally, do you know the right amount of water to give each plant in your garden to make it thrive?

All of these questions can be easily resolved by the technology being developed to integrate and automate gardening.  How it works:

  • Base Station: A networked base station in the house connects to your home WiFi network and also the low power garden network.
  • Distributed Sensors: Sensor modules which run on batteries and are charged by solar power are placed throughout the garden in strategic locations to collect information on ground moisture, temperature, humidity, and other information in real-time.
  • Watering: You install a watering system to disperse water appropriately. There are many options for how to do this, with varying expense.
  • Valves: Install wireless controlled water gates which can controlled manually from any internet enabled device, or, can be connected to a base station for automatic (smart) operation.
  • Learning: By monitoring the level of moisture achieved by various amounts of water, the system learns your drainage and soil type to optimize when to water, and how much.
  • Tuning/Zones: Not every plant requires the same amount of water. Configure your base station with information on what plants are near each sensor, and the base station will use this information to control the amount of water delivered.

The prototype of a sensor node is shown below.  The screen is only to show the status of the system.  Visible directly above the screen is the ultra low-power wireless module.  The zig-zag wire is the antenna.  To the left of the antenna, you can see the CPU.
