Abstract

There were several alternatives that can be used to generate electrical energy, one of the ways is by using solar cells, to fulfill the needs of electrical energy. This solar cells utilization very fit with indonesia climate because indonesia has tropical climate, where the sun shines all year round. Not only that, this energy is renewable, clean and environmentally friendly. In other words this energy inexhaustible and safe as long as the sun can shine. The generator that can be used to produce electrical energy called PV, as it is known, PV itself is a generator that produces DC electricity. In this situation, an inverter is needed to be able to convert DC to AC, because all properties used at home require AC power. In this research the researcher use a PV generator source with 90 Watt-Peak power, therefore the inverter is made to adjust the capacity of the PV generator, where the switching process uses the IRF44n type mosfet, with the mosfet driver using IC type IR2110, where the switching process is itself controlled by Arduino with the SPWM method. so that the output of the inverter is an AC voltage with a frequency of 50HzKeywords : PV, Arduino, Switching, Inverter

Abstract

Along with technological advances in modern times, and the development of science, human needs are also growing. In order to facilitate human work, many technologies have been created using automatic systems. One of them is in the case of automatic plant watering for farmers or garden owners. For this reason, the authors carried out a design of automatic plant sprinklers based on the YL-38 type soil moisture sensor which will be controlled by Arduino. Which later will send a duty cycle to the buck converter to change the voltage automatically according to soil conditions which have been grouped into four parts, namely very dry, dry, humid, and wet. Changes in voltage will affect the rotational speed of the motor according to the needs of the ground. With real time watering, the RTC DS1302 type is used so that this watering will be more scheduled. This watering uses a supply from a 12 volt DC battery with a 12 volt water pump motor load. Keywords : duty cycle, buck converter, arduino, soil moisture sensor.
