Controlling Electrical Bulb Through Mobile Based on Light Intensity

Abstract

Home automation is one of the most important emerging sectors that has the potential to change the way people live. Some of these home automation systems are aimed at individuals looking for elegant and complex household automation structures, while others have been concentrated at those with specific requirements, such as the elderly and handicapped. A typical wireless domestic automation device allows one to regulate home preservation appliances from a wireless centralized control unit. For the most available commercially domestic automation systems, those household appliances must be designed in a certain way to be well-matched with one another and with the manipulation unit. The innovative machine may be used as a standalone portable unit to control lights, air conditioners, television sets, security cameras, electronic doors, computer structures, audio/visual equipment and other devices remotely. And you can switch ON or OFF any device that is hooked into a power socket, as well as obtain the status of different sensors and make choices based on that information. The device is portable and designed to be easy to set up, configure, use and maintain. However, the ideal consumer interface does not yet exist, and creating one needs the experience of experts from each sociology and period subject. We can know the state of the light from anywhere in the globe with this technology. The proposed work is to know the status of the light intensity and operate the bulb accordingly from the mobile. The status of the light will be shown on the Blynk app. Here, a mobile application is created, and the NodeMCU gets intensity of light data from the sensor and sends them to the smartphone application. Using the mobile application, we can switch ON or OFF the bulbs using the relay.
