IOT-BASED HOME APPLIANCES CONTROL SYSTEM USING NODEMCU AND BLYNK SERVER

Abstract: The fundamental purpose of monitoring electronics appliances in the modern world by using Internet of Things (IoT) is to control them based on situational demands. With the advancement of technology, the need for efficient controlling is more as it optimizes performance and saves unnecessary wastage of power.The basic home appliances are fan, light and water pump which consume maximum power.Unnecessary wastage of power and resources by turning on lightsduring daytimeor high speed fans in winter season or water pump during overflow of water from tank can be avoided in this way. A system has been proposed to control home appliances anytime from anywhere in the world and efficiently utilize power by controlling appliances properly.Blynk app has been used to read data from sensors located in home environment and user controls home appliances based on these data. Being busy in hectic schedule of daily life user may not be able to read sensor data continuously to take some action through app. So the designed system sends an emergency notification in user's mobile app.
