Perancangan dan Implementasi Lampu Jalan Otomatis Serta Pendeteksi Pergerakan Manusia Untuk Mencegah Maling Berbasis Tenaga Surya

Abstract

Lights are electronic devices that work or can light up when given a current. This street light receives current from solar panel power. Where the solar panel functions to capture the energy of sunlight and convert it into electricity then the control charge will set it to charge the battery. The battery functions to store current from the solar panel so that when the solar panel is not working the current can still be flowed. Then from the battery, the current is changed from DC to AC voltage on the inverter which will later be supplied to the circuit using an adapter. Adapter or power supply serves to supply current from the inverter to other electronic circuits. Current is supplied to the Atmega328 which functions as the control center of the entire circuit so that the lamp can turn on automatically with the lamp working hours from 18.00-06.00 which is set by RTC DS3231. The RTC DS3231 functions as an RTC (Real Time Clock) or digital timing as well as the addition of a temperature measuring feature that is packaged into 1 module. And there is also a PIR sensor that functions to detect movement in humans around the lamp to prevent theft, for example when the lamp is about to be stolen, the PIR sensor will detect the presence of the lamp. infrared rays that approach and at that time the buzzer emits a sound output. As well as the LDR sensor which functions to detect if there is damage to the lamp.
