Otomatisasi Pencahayaan Ruangan Menggunakan Sensor Pir Berbasis Aruino Uno
ABSTRACT
The use of room lighting that stays on when the lights are not needed can cause
less efficient use of electrical energy. This study aims to create a device that can
turn on and off the room lights automatically based on the Arduino Uno which is
triggered by human body movements, and produces a warning signal when there
is or is not a person in the room. This tool uses a motion sensor (PIR) sensor, a
RYG LED module, a relay module and a 220 VAC lamp. When the body
movement is detected through the PIR sensor, the sensor will read HIGH logic
then, Arduino will turn on the room light via a relay and activate the 220 VAC
lamp, which in the original state of the lamp contact is in a NC state (normally
closed ) changes to open where this change in position causes The room lights
are on. From the test results, it can be concluded that the room light automation
system based on Arduino Uno has been successfully implemented according to the
design.
