Sprinkler/Help

This is the Manual/Help Page for the Sprinkler software.

Prerequisites

• Oracle Java Runtime 8

or if you'd like to build the Sprinkler software yourself:

• Oracle Java Development Kit 8
• Maven 3

Installation

Download the software for your platform from #Downloads or build the software yourself

Starting

Run the software with java -jar sprinkler.jar or sprinkler (If you built the software yourself: cd com.bitplan.sprinkler/release before this command)

Setup

Sprinkler performance

The system needs to know how much water your sprinkler will apply per hour. To test this you need:

• a cylindric container - any jar or utensil will do that has a uniform cylindric diameter
• a letter or household scale that can measure to grams
• a ruler

Put your container on the lawn and sprinkle for 1/2 hour.

You could now measure the water level directly with a ruler. The result will be more precise if you use the scale. Weigh the container 3 times

1. with the amount of water the sprinkler applied in 30 minutes
2. empty
3. the container full to a set level e.g. 10 cm

In our example we got the results:

1. 83 g for the container with amount of water the sprinkler applied in 30 minutes
2. 37 g for the empty container
3. 750 g for the container full to 10 cm (100 mm)

Now we are interested in what the equivalent of mm rain per hour of this sprinkler is. To calculate this we can use this excel sheet.

In our example the result is 12.6 mm per hour. Given the size of the lawn the sprinkler covers is 100 square meters this is equivalent to 1260 l of Water per hour.

Weather Forecast

The weather forecast screen shows the rain forecast for your location from the openweathermap.org as a block diagram with 3 h blocks for the next 5 days.

Location settings

You can lookup your location by name if you enter the name and Country code of your location and erase the id field. The id, longitude and lattitude will then be automatically looked up from the openweathermap.org location list.
