Perancangan Catu Daya Hybrid Sebagai Sumber Energi Pada Lampu Lalu Lintas Pintar

ABSTRACT

The need for energy in the world continues to increase while the source of fossil energy used continues to run low. So that an alternative energy is needed to replace this energy, namely a power supply in the form of a solar panel where the voltage of the solar panel is controlled through the SCR and then the relay is used as an infrastructure to store the voltage to the battery via solar cells or through a PLN source where Arduino Uno is the brain in the running of the system when If a problem occurs, Arduino Uno will work to the relay to change the voltage source to the PLN source. If in normal circumstances, Arduino Uno will control the relay via solar panels to turn on traffic lights.

Keywords : Solar Panel, SCR, Battery, PLN Source and Arduino Uno
