PROTOTYPE OF AUTOMATIC WATERING USING RTC (REAL TIME CLOCK)

BASED ON ARDUINO MEGA 2560 MICROCONTROLLER

AT HARUM MANIS MANGO BULELENG BALI

Increasing market demand, demanding the harum manis mango farmers of Buleleng Bali to go the extra mile in maintenance to maintain the quality and increase the amount of production of sweet fragrant mango harvest. This will result in increased operational costs as well as daily laborers' wages.

Based on this, one efficient way to assist the work of farmers is to utilize appropriate technology. One example of the use of appropriate technology in agriculture is to implement an automated system. The automated system can work independently so that it can improve the efficiency of farmers' working time.

Based on this, the researcher designed an automatic watering system based on scheduling that can be set according to the user's wishes. This system utilizes RTC (Real Time Clock) as a time indicator and Arduino Mega 2560 microcontroller as the main control. Watering time setting is done by using a keypad that is composed of several push buttons. There are 3 watering time sessions that can be used, each session can be set according to the user's desires. LCD is used to display information in the form of time, date, month and year.

In the test that has been done, there are 3 watering sessions that are used namely morning watering session conducted at 09:15. Daytime watering session conducted at 13:05. On afternoon watering session conducted at 16:10. The three watering sessions are time settings conducted by using a keypad on the automatic watering device. The watering process will be active, when the clock displayed on the LCD is the same as the given time setting. The pump will be activated, indicated by the indicator LED on the relay module not lit, and vice versa. The watering process will stop when the clock displayed on the LCD is more than the given time setting, so that the watering will automatically stop. Based on the test results obtained, automatic flowing equipment using RTC (Real Time Clock) can work well, so it is expected to simplify the work of the farmers.
