Prototype design of automatic plant watering equipment with soil moisture detection system based on arduino uno microcontroller: case study of chili plant

Abstract. Indonesia is an agrarian country, and most of the population's livelihood is in the
agricultural sector. One of the results of agricultural commodities is chilli. The chili is a vegetable
commodity that cannot be separated from the daily needs of the community. In the process of
planting chili plants, water requirements greatly affect the growth of chili plants. However, along
it was with the occurrence of delays in watering, especially in the dry or hot season. Watering
chili plants based on soil moisture was one way to treat chili plants properly. Using the Arduino
Uno microcontroller was as the main controller for the automatic chilli watering program. The
program received input from the sensor soil moisture. The soil moistures were a sensor that
worked to determine soil moisture, so when the soil was under certain humidity conditions it can
water the chilli plants automatically.
