Arduino Based Automatic Curtains and Light Dependent Resistor (LDR) Sensors

English

Abstract

Today's technological developments provide very real changes in human life. There are many tools made to facilitate human work. With advances in science and technology, innovations are developed that are better. Automatic control systems in the field of science and technology lately also growing rapidly. This can be seen from the range of applications ranging from household to sophisticated equipment. Automatic curtains using Arduino-based light sensors are an idea that arose to meet the needs of home automation systems. Automatic curtains work based on the intensity of light that is captured by the light sensor and is real to be processed by Arduino and gives the task of the driving motor to carry out orders to go up or down the curtain according to the light intensity settings that have been set to the system. Simply put, when the light intensity is 271 - 1000 lux then the curtain goes up, then if the light intensity is 1001 lux the curtain will go down, and if the light intensity is 270 lux then the curtain stays down or closed.
