There is a need for more dynamic control over residential irrigation to conserve our precious water resource. This paper looks at developing a design for an Internet based “Smart Controller” for use in a residential sprinkler system to solve some problems that traditional controllers inherit. With the introduction of Web based dynamic control brings new expense to the overall system however, this project yields a controller that would be very competitively priced among the current residential market for irrigation controllers while opening a new window of opportunity into water management and conservation.
