Abstract
The automatic watering of plants with solar energy is an artifact science project type. Created to build
and develop automatic watering systems using solar energy. And to test the performance of the
automatic watering system using solar energy. In which the organizers can use solar cells as an energy
source for pumping water and using the Kidbright robot board, Sensor receiving board iKB-1 and Soil
Moisture Sensor to control watering plants. When the soil has less than 65 percent moisture, the
Kidbright board will put the Output 1 to On to order the relay switch board to work with a 12-volt water
supply circuit. The water pump will water it into the plot. Planted until the soil moisture is greater than
65 percent.
When the plot is over 65, the Kidbright board will work for Output 1 to be Off to order the relay switch
board to cut off the water supply. Stop watering the plants. While displaying data via the Blynk and
LINE applications. Results of the performance test of the automatic solar watering system It was found
that the total average time of watering the plants with solar energy was tested for 1 week is 27 minutes.
The time to water the plants automatically with solar energy in the morning is an average of 15 minutes
and the average evening is 12 minutes. Therefore, it is considered that the solar automatic watering
system can water and stop watering the plants automatically according to the humidity that determined.
It also has automatic watering systems with solar energy to help facilitate watering plants. And reduce
the burden of daily work
