Tingkat Intensitas Cahaya di dalam Ruangan dengan Menggunakan Sensor LDR Berbasis Arduino UNO R-3

Abstract

Has designed a measure of light intensity levels using LDR sensor. The working principle of a series of light sensors on sebenarya very simple. Voltage division between VR1 and LDR is at the core of the light above the sensor circuit. The increase in the voltage at VR1 will reduce the voltage falls on LDR, vice versa rise in LDR voltage will reduce the voltage drop on the VR1. Voltage division in accordance with the formula that applies a voltage divider in a series circuit, the voltage supply 9 volt is equal to the amount of voltage on R1, VR1 and LDR. Arduino is an electronic circuit that is open source, and have the hardware and software that is easy to use. Arduino can recognize the surrounding environment through a variety of sensors and can control lights, motors, and various other types of actuators.
