SISTEM IRIGASI BIG GUN SPRINKLER PORTABLE PERIODIK DENGAN MIKROKONTROLER ARDUINO

Abstract

Barren land can have a social impact on people living in the surrounding area. Land that should
be used as dry land is caused by the condition of the land lacking water, so technology is needed that
can improve the efficiency and effectiveness of water use, namely sprinkler irrigation. This sprinkler
irrigation is supported by a big gun sprinkler that is capable of spraying water into the air as far as 20-
30 meters, the water distributed can be uniform as rain so that production can be uniform and optimal.
This method can take place if the sprinkler big gun that presses 2 to 6 bars is supplied with a water
pump that can provide that much pressure too. This system consists of a DHT22 sensor as an input to
read the temperature and humidity values of the air. Arduino microcontroller as input processing from
temperature and humidity sensors (DHT22) as well as main processing. The output is a water pump
and sprinkler that is used to spray water into the air. There are 3 main modes, namely auto, timer,
manual, auto to run the tool automatically and periodically. Timer to run the system with time mode in
minutes with a 10 minute increment in stages, manually to run the tool manually which needs to turn
on and turn off the pump with the help of human power. The temperature changes carried out by the
tool are the fastest with a duration of 3 minutes 42 seconds when the temperature of 33 degrees drops
to 32 degrees Celsius and the longest with a duration of 5 minutes 45 seconds. The most rapid change
in humidity is 1 minute 35 seconds when 51 percent humidity rises to 52 percent and the longest with a
duration of 3 minutes 1 second when 49 percent humidity rises to 50 percent. In testing the entire tool
by running the auto mode the system will automatically turn on when the temperature <value is set
and humidity> value is set and will automatically turn off.
