Implementation of wireless smart home using IOT

One of the major emerging sectors that has the potential to alter how people live is the smart home. A typical wireless smart home automation system enables one to operate household appliances from a wirelessly connected to a central control unit. For these appliances to work properly together and with the control unit, they typically need to be specially built. One can wirelessly control air conditioners, lights, fans, television sets, security cameras, computer systems, audio/visual equipment, electronic doors, etc. withthe developed system, which can be integrated into a single small unit. One can also turn ON or OFF any appliance that is plugged into an electrical outlet., find out the state of various sensors and make a judgementbased on it. The system is designed to be simple to install, setup, use, and maintain. Soon, voicewill be the main point of contact between people and technology. The issue is the state of the elderly or disabled, who frequently need outside aid to move around and are unable to help themselves. Those who live alone could also want assistance around the house. As a result, a system for voice-controlled wireless control of household appliances is created so that users can carry out specific operations using voice commands. In our present day to day life in smart home devices can be controlled using a single platform like google assistant or Alexa. This paper mainly focuses on developing one product which can be controlledusing multiple devices. This paper is based on the integration of various sensors like LDR sensor, temperature sensor, IR sensor and humidity sensor which collect the information and process the output based on the user commands. It also focuses on developing a universal remote using IR sensor to control multiple devices using a smartphone.
