Prerequisites
or if you'd like to build the Sprinkler software yourself:
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
- with the amount of water the sprinkler applied in 30 minutes
- empty
- the container full to a set level e.g. 10 cm
In our example we got the results:
- 83 g for the container with amount of water the sprinkler applied in 30 minutes
- 37 g for the empty container
- 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 22.8 mm per hour. Given the size of the lawn to be 100 square meters this is equivalent to 2280 l of Water per hour.
