Design and implementation of GSM-based home automation

Abstract

Home automation systems are growing in popularity because they can increase convenience, comfort, and energy efficiency. Automating curtain control is a crucial component of home automation because it maximizes the use of natural light, which can lower energy costs by reducing the need for artificial lighting and increase indoor comfort. Hand-operated curtains frequently result in inefficiencies, like daytime exposure to excessive sunlight or underuse of natural light, which raises the cost of energy for lighting, heating, and cooling. Furthermore, regular manual adjustments might be cumbersome, especially for windows that are difficult to reach or for people who are elderly or disabled. I suggest an Arduino Uno-based automatic curtain opening and shutting system as a solution to this problem. Light Dependent Resistor (LDR) sensors are used by this system to sense the amount of ambient light and modify the curtain position accordingly. The curtains open to let daylight into the room when there is enough natural light detected, which lessens the need for artificial illumination. On the other hand, to preserve comfort and privacy, the curtains close when light levels drop or become too strong. The curtains are physically moved by a motor (a DC motor), which is controlled by the Arduino Uno microcontroller once it has processed the data from the LDR sensors. In addition, the system has physical switches for manual control, enabling users to override automatic processes as needed. This straightforward yet efficient method provides an economical means of incorporating smart technology into homes, offering advantages in terms of reduced energy use and improved user comfort. This project shows how accessible technologies like Arduino and sensors can be used to improve everyday living circumstances in a sustainable and intelligent way by automating curtain control.
