Sprinkler/Help

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. Weight 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
