Sistem Penerangan Rumah Cerdas Menggunakan Solar Cell Berbasis Mikrokontroller Atmega32

Abstract

Along with the rapid development of technology, the higher the human need for electricity. Because almost all of the tools - an electronic device needs electricity in use. However, limited natural resources (SDA) that is making the power supply is not comparable with the needs of the community. Utilization of solar cell as a power source, is among the utilization of renewable energy, because solar cell is connected with the flow of energy derived from "natural processes are sustainable". The design tool intelligent home lighting system comprises two solar cell, 2 batteries, the minimum system, and 6 super LED lamps. The working principle of this smart house is the work of a microcontroller system operation as set battery charging time of solar cell at 06.00 am to 19.00 night automatically, and the operation of the battery turns from 19.00 pm to 06.00 am automatically. With the location of the position lights, the users of these tools put two super LED lights in parks, 2 super LED lights in the kitchen, 1 super LED lamp in the garage and 1 super LED lamp on the porch as testing. Based on the results of the design tool, this intelligent home lighting system that use battery as a source of reference voltage to enable the microcontroller that will move the entire control system can be run properly. Although the test results either from the battery charging and discharging is unstable. Dependence battery charging area based on the location of the light that strategy, the weather was nice and rotation time as well as battery consumption due to daily usage of the user at night.
