Automatic Home Appliances Controller Using Arduino

Abstract

Arduino plays a very vital role in the development and implementation of automation technology. Automation is the process of controlling system and information to decrease the need of human participation. Home automation represents the idea of controlling of home appliances in an integrated system. It may include the control of lighting, heating, ventilation, air-conditioning, security, and other appliances. Several sensors i.e. detector for temperature, smoke, fire, gas, PIR, light, etc. are used for smart home. These sensors use the input signal to control home appliances. But implementation of a unified connectivity between devices and the main controller in cost effective way is very decisive this works includes the control of switching of lights and fan as per the attendance of person, speed control of DC motor (fan) according to the variation of temperature. Thus, the speed of DC motor is controlled through duty/PWM signal. In this synopsis, we present a flexible and reliable control scheme for controlling the DC motor and light control. Pulse width modulation (PWM) or pulse duration modulation are commonly used technique for controlling power to the internal electrical devices, made practical by modern electronic power switches.
