Internet of Things (IoT) conceptualizes the idea of remotely connecting and monitoring real-world objects (things) through the internet. When it comes to our house, this concept can be aptly incorporated to make it smarter, safer and automated. This project presents the overall design of Home Automation System (HAS) with low cost and wireless system. The smart home concept in the system improves the standard of living at home. Whenever a person comes in front of the house the PIR motion detector sensor detects the person and a message will send to the house owner and he can see the person through the camera in front of the house. The camera is accessed to the webpage and also the light, fan, door lock, an alarm can be controlled with the webpage. The system intended to control electrical appliances and devices in a house with relatively low-cost design, user-friendly interface, and ease of installation. According to the priority of the person, the owner can control the electrical appliances. Those who get the authentication can unlock the door by entering a password on the keypad and use the home appliances depending on the priority set by the owner.
