Title: Smart Predictive Sprinkler

Description:
BACKGROUND 
     With worldwide freshwater resources getting depleted at an alarming rate a disproportionate amount of water is wasted with timer-based sprinklers. Energy is wasted adding to global warming. The ASPSS device addresses this problem. 
     SUMMARY 
     ASPSS is a smart electronic sprinkler valve controller. It works to make sure that a sprinkler system operates efficiently only when needed to keep the turf green while eliminating wastage of precious sweet water. ASPSS has built-in intelligence to capture soil-moisture data from strategically placed capacitive moisture sensors in the area to be watered. It connects to an internet cloud service to gather weather forecast data through any existing WiFi network. Based on the data collected ASPSS decides on when to switch on or switch off sprinkler solenoid valves. It has embedded artificial intelligence to wait in case of upcoming precipitation.

     DETAILED DESCRIPTION 
     ASPSS is a smart controller device that:
           1 . Can be programmed to operate at certain times of the day (similar to existing timer-based sprinkler controllers),   2. Measures many factors such as soil humidity of a sprinkler zone, surface temperature of that zone, atmospheric humidity,   3. Has an active built-in LCD display. However, the said device&#39;s primary interface is through a mobile/web application,
           a. The mobile/web application will be able to set parameters such as current date and time, operating times of the device.   b. The user of the device will also be able to fine tune parameters such as threshold humidity, threshold temperature etc. for operation.   
           4. Integrates directly with weather data providers. Therefore, if there is a prediction of precipitation it waits to make sure that the precipitation indeed happens before deciding to operate.   5. Has an internal algorithm, that determines operation of solenoid-valves that switch on or off to provide water to sprinkler-heads.   6. Decides if there is any requirement for additional moisture at a zone and whether operating the sprinkler-heads of that zone will not end up with most of it evaporating.
