Rancang Bangun Sistem Pengendali Lampu Rumah Mobile Smartphone Dengan Arduino

Abstract

In people's daily lives, one of the important factors that is very supportive is the existence of lighting, this electronic device is very useful in low-light places, especially at night. To get lighting, the lights are turned on and off manually. For some people, that is not a problem, but for people whose daily activities are often done outside the home and often traveling in, turning the lights on and off becomes a big obstacle. It also causes waste of electrical energy, and can lead to electrical shocks because this study designed an android and hardware application that is equipped with a light sensor to turn on and turn off the lights automatically based on the Atmega328 microcontroller and can be controlled remotely via a smartphone. Arduino Uno microcontroller as the main controller module. Messages or data sent from the smartphone will be received by GSM 800L to be forwarded to the ATMega328p microcontroller on the Arduino. The data received by the microcontroller will be processed and executed to control the relay circuit. The relay serves as an electromechanical switch to turn on and extinguish the lights then the notification is forwarded in the form of SMS to the mobile phone via the GSM SIM800L module as a feedback system report (feedback) which serves to determine the position of the lamp is turned on or off.
