IoT is also used to sense and control these devices remotely. With the help of sensors, IoT is used to connect the physical devices, called as things, with the cloud server. Now with that cloud server user can be able to control the device and send their commands. After the cloud receives the command from user, it sends the signal to the physical device and device then perform the intended action. Various types of microcontroller are used for mapping command to signals such as Arduino Board, Raspberry pi card, Hardware interface module and lot more. For connection of device to internet we IoT uses various wireless radios such as: Wi-Fi, low-energy Bluetooth, NFC, RFID, Zig Bee, Z-wave etc. In this paper, the implementation of IoT for home automation system, and comparison of various technologies used for home automation system considered on their cost, performance, security, reliability, power consumption etc. were discussed. Keywords: Arduino, Raspberry, IoT, RFID, sensors. 1. Introduction IoT is a rapidly emerging technology which is actually a network of physical devices vehicles, buildings and other items that are embedded with electronics, software, actuators, sensors, and network connectivity that enable these objects to collect and exchange data. About a decade ago if we ask how many objects did we have connected to internet then answer probably would have 1 or 2 but today we have a lot of devices connected to the internet such tablet, smart phone, personal computer, work computer, video game console, media player, smart television, smart refrigerator and many more. It is estimated that by 2020 there will be 50 billion objects connected to internet which means there will be billions of sensors blanketed around the world. These sensors will be taking the information from
